Electrical compressor connection diagram from air conditioning

A solid arrow of the scheme shows how the device works in cooling mode, dashed. in heating mode. In more complex air conditioners, in addition to the above mechanisms, the oil separators, pressure sensors, injection sensors in the compressor, separators of liquid freon and restarting lines.

Electric circuit of the external module

When you have a connection diagram of the air conditioner compressor, you can proceed to the procedure. But there is one more prerequisite: you can change the compressor only for the unit recommended by the manufacturer.

  • dismantling the old compressor from refrigerator and electrical circuits;
  • installation of a new unit;
  • replacing the filter-dryer;
  • sealing the unit using a vacuum pump and other equipment;
  • refueling the system by freon;
  • Testing climate technique in all modes.

It should have the necessary pressure. However, to replace the elements, it is not always possible that some modifications are no longer presented on sale to eliminate this kind of malfunction, you can use one of the ways: to clean the surface, which extends the service life of at least 3 months, or repair, replacing contacts in terminal clamps. For a single.phase engine, a relay is used on a volt, with two connections.

In the process of functioning, the indicators formed as a result of the elastic force of stretching or compression of the springs and the onslaught of the atmospheric. The membrane of the container is connected to the switch of the press. The contact of this relay supplies power to the electromagnetic computer valve, which opens the access of cooling water to the compressor’s foreign space. The author of the article describes the existing types of pneumatic relay in detail.

Below is a circuit for connecting automation to three phases. In accordance with the nominal value of the power line, the corresponding model of the relay unit is selected.

Remember that compressor depressurization should be made no earlier than 5 minutes before soldering. Share your own experience in the operation of the compressor with a pressure relay, ask questions, publish photos of working and launch capacitors for dummies.

Principle of operation

Sold up the tubes from the compressor and capacitor, Set the filter-dryer.

Since the air pressure regulator is connected to the receiver, the compressed air from it enters the membrane block of the relay.

Solder a new filter-dryer. In Fig. With a decrease in the compression level in the receiver, the membrane installed in the pressure regulator is bending down. Even having extensive experience, it is difficult to make a similar mechanism. Configure the parameters of the highest and smallest pressure in the system using adjusting screws. According to the factory standardized settings, the elastic coefficient is set to pressure in the AT pneumoceum, as reported in the instructions for the device. specifically. one phase will be constantly connected to the load after connecting to the power supply, it is necessary to deal with the additional capabilities presented in the air blocks for ejectors.

Be sure to disconnect the device from the mains and remove the cover from the press.steam. It should not be directed inside the pipes, since plastic elements of the nodes from heating can be deformed or completely melt. Large screw clamp and the spring are designed to control compression parameters. It is determined by the characteristic whistle and the feeling of a sharp cold draft near the case.

How to connect a compressor: Instructions

The mechanism works when it passes through certain elements of electric current. When the pressure changes, the spring mechanism turns on, and the relay closes or opens the electrical. However, manual adjustment of the range of two values ​​is also possible. maximum and minimal, but only towards the decrease. Connect the wires from the engine to the electrical connector of the device. Connect a pressure gauge, safety and unloading valves through the flange connectors. Caution should be taken so as not to bend the lamella. There may be several sources. Depending on which engine is installed in the compressor, on B or on B, there are different spacecraft connection schemes.

The press start for the compressor wears out, working in difficult conditions, and fails. The mechanism remains in the open position at the start of the engine during a given interval. After checking the resistance, it is necessary to measure the current strength. How to set up a compressor on an ON and off

Step.by.step instructions for connecting the air conditioner compressor

When you have a connection diagram of the air conditioner compressor, you can proceed to the procedure. But there is one more prerequisite: you can change the compressor only for the unit recommended by the manufacturer.

  • dismantling the old compressor from refrigerator and electrical circuits;
  • installation of a new unit;
  • replacing the filter-dryer;
  • sealing the unit using a vacuum pump and other equipment;
  • refueling the system by freon;
  • Testing climate technique in all modes.

Typical installation errors

The standard errors made by non.professional are the following:

  • Failure to comply with vacuumization or the procedure is wrong, the result of such actions will be: the presence of water vapors in the freon line, high condensation pressure, and then a breakdown in the insulation of the engine;
  • violation of installation rules, including pipe creases, non-compliance with slope angles, long routes and more, because of this, the compressor lubricant system fails;
  • poorly executed connection of the joints of the freon’s tracks;
  • entering foreign substances in the highway.

If you avoid these errors in the process of connection, you can count on the performance and effectiveness of the split system. But, if you are uncertain in your knowledge, it is better to entrust the work for professional masters of the service brand of climate technology.

DIY air conditioning connection. Working scheme step by step

Installation and connection of the air conditioner is a complex process, the implementation of which is better to entrust professionals. Nevertheless, if there is a fundamental desire to save money, you can perform such an operation with your own hands. But for this it is necessary to meticulously observe the safety rules, know the requirements for connection, as well as the procedure for its implementation. About all this. in this material.

When installing and connecting to the air conditioning electrical network, the safety rules should be followed. It is especially important to take them into account when choosing a socket and cable.

Important! The desire to save on the services of a specialist or materials may result in failure of equipment or fire.

Cable requirements

To understand which wire is needed to connect a split system, you need to contact the user management. It is very important to choose a cable recommended by the manufacturer himself. Typically, to connect domestic air conditioners, there are enough wires with a cross section of 1.5 to 2.5 mm2 and a current force up to 18 amperes. if the distance from the electrical panel is up to 10 meters, there is enough cable with a section of 1.5 mm2, otherwise the thickness of the wire must be increased.

To make the connection reliable and safe, the cable must be copper. If the connection is single.phase, you need a three.wire wire, and for a three.phase. in five cores.

Important! The wires should pass in a meter or more from heating or gas supply pipes.

Roset requirements

There are several mandatory requirements for the outlet.

  • A high-quality outlet should have a grounding or differentiated relay, as well as fully comply with the requirements compiled by the manufacturer and set forth in the operation manual for the split system.
  • The wiring suitable for the outlet should be copper. If an aluminum cable is summed up, it must be replaced with the required taking into account the correct section.
  • The outlet must be connected to the shield through a protective machine.
  • All work on the connection should be done by a specialist, otherwise the manufacturer may refuse warranty service. If the user does everything independently, it is necessary to act in accordance with the requirements and very carefully.

Methods of connecting to the existing electrolyte

To connect the air conditioner to the existing electrolyte, the wiring is laid along the wall (external) or inside the wall in the strobes (internal).

External wiring

When laying external wiring, it must be tightened every half.meters with plastic clamps and fixed with screws to the wall.

Advice! In order for a new electric fishing line for a trimmer to look aesthetically pleasing, it is allowed to be hidden in a cable channel, which is attached to the wall with self-tapping screws or glue.

Internal wiring

To lay a cable for connecting a split system inside the wall, the surface is pre-stroke to the desired depth. Next, the wire is cleaned in a plastic corrugated tube, placed in a prepared groove and fixed with clamps. In the event that the cable is hidden at a depth of two or more centimeters, the corrugated tube can not be used. Hubs are plastered with construction gypsum.

Important! It is forbidden to lay wires in bundles. The distance between them should be more than 3 mm.

Connecting air conditioner

Connecting the air conditioner must be carried out very carefully. incorrect or careless actions can lead to failure of equipment, and the price of the repair will be very high. If there are doubts that it will be possible to do the right job yourself, it is better to contact professionals.

Connection of inter.block cables

The cable from the outer block to the internal stretches through the hole in the wall along with the pipes for the circulation of the refrigerant and the drainage tube. Then it connects to the evaporator and compressor.

Connecting the evaporator

To connect the evaporator located in the internal unit of the air conditioner, you need:

  • remove the front panel;
  • Remove the protective casing;
  • Remove the cable lock from below;
  • remove protective insulation from the veins of the cable previously carried out through the wall, retreating from the edge of 2-3 cm;
  • insert the bare ends of the veins into the terminals, tighten with screws;
  • strengthen the wire with a fixer;
  • put on a protective casing;
  • Install a decorative panel in its former place.

Important! Similarly, the cable is connected to the external unit. Before included in the network, you need to carefully inspect the connections and make sure that the cable is connected correctly. in accordance with the electric circuit.

Now it is necessary to connect the equipment to the network through the outlet or directly to the shield.

Connection to the outlet

Home climatic equipment usually connects to the network through a socket. This method is suitable for ordinary or inverter split systems, window (for example, BC 1500) or mobile air conditioners having a low capacity up to 4 kW.

It must be remembered that the air conditioner requires an individual outlet, to which the connection of other equipment is excluded. It is not recommended to use the extension cable if the cable length is not enough to reach the outlet, you should completely replace it with a suitable.

Connection to the shield

A separate fishing line for a trimmer is used for electrics of industrial air conditioning systems or powerful household climate equipment, for example, Mitsubishi MU-GD80VB. This is necessary so that the device receives food on its own branch and does not load the working fishing line for the trimmer of the house, preventing the normal operation of other devices.

Important! The shield to which the fishing line for the trimmer is carried out must be groundlessly grounded.

The power cable during a direct connection to the shield is carried out in a strob or a cable channel directly to the internal block of the air conditioner. The cross section of the wire is selected in accordance with the distance from the device to the shield and the recommendations of the manufacturer. The technique will work without an outlet, and it will be possible to de.energize it using the installed machine, the power of which is also selected according to the instructions.

Pipe laying

In addition to connecting the wiring, an important stage of installation of the air conditioner is the gasket of pipes. They are used to circulate the refrigerant in a liquid and gaseous state from the internal to the external unit. The connection of the tubes for connecting is performed through a special hole in the wall, which breaks through a slight slope outward so that the liquid along the drainage hose moves by gravity. If the drainage is connected to the sewer of the house, this rule is not necessary.

Air conditioning: scheme and principle of operation

Despite the fact that the air conditioners are in almost every house, only a few users correctly imagine a diagram of such a device and how it works is connected. In this article we will try to unfold this topic.

General scheme of air conditioning

The entire system is built on the ability of substances to absorb heat during evaporation and secrete it during condensation. This air conditioning scheme is laid down in the work of a modern split system. The main substance inside the closed system of the device is freon. Having the opportunity to change its aggregate state by changing temperature and pressure, we will be able to cool the radiator and drive air through it from the street.

But first, we will get acquainted with the main elements of the split system. The scheme and principle of operation of the air conditioner suggest the use of two blocks: external and internal. What are they needed for?

External block

This block is installed on the street and mainly serves to cool the overheated freon (it does not take the air from the street, the air conditioner serves to cool air in the room. Ventustinations are used for street air. It consists of the following nodes:

  • Fan.
  • Capacitor. In this part, Freon is cooling and its condensation. The air that passes through the capacitor is heated and diverted to the street.
  • Compressor. The main element of the air conditioner, which compresses Freon and ensures its circulation along the entire contour.
  • Control block. It is usually used in external blocks of inverter systems. In ordinary air conditioners, all electronics are most often in the inner block.
  • 4-lane valve. It is used in models that can work for heating (most modern air conditioners). This element when activating the heating function changes the direction of the refrigerant. As a result, the external and internal blocks change places: the internal works for heating, the outer. for cooling.
  • Various studio compounds through which copper pipes between the internal and external blocks are connected.
  • Reflash filter. It is installed in front of the compressor in order to protect the latter from dirt, which during installation can get into the system.

Inner block

  • The front panel through which air enters. It is easily removed so that the user can get to the filters.
  • Crushing filter is an ordinary plastic grid that delays large dust (for example, animal hair, fluff, etc. D.). This grid needs to be cleaned once a month.
  • Filter system consisting of coal, antibacterial, electrostatic filters. Depending on the model of the air conditioner, some filters may not be at all.
  • Fan for the circulation of clean air in the room. cold or heated.
  • Evaporator. Is a radiator where the ice refrigerant enters. This radiator is very cooled by freon, and the fan drives the air through it, which instantly becomes cold.
  • Blinds of air flow adjustment.
  • The indicator panel shows in which mode the air conditioner works.
  • Management payment. It has a central processor and an electronics unit.
  • Steper compounds. the pipes of the connection of internal and outdoor units are connected to them.

The air conditioning scheme is simple and logical, but some users do not understand why two blocks are needed? After all, you can take warm air from the room and drive it through the air conditioning, cooling it. But not everything is so simple: you cannot produce cold without making heat. And heat needs to be taken outward. For this purpose, a two.block system is ideal. There are also other systems, such as single.block. There, heat is driven out along a special duct led outside the apartment.

Now that you know the main elements, you can consider in more detail the scheme of this system. So, when activating the cooling mode from the control panel, the compressor is turned on in the system. He pumps pressure and drives gas through the radiator. Having passed the radiator (in the outer block), the gas becomes liquid and hot (if you remember, with condensation it releases heat).

Now the hot liquid freon (which was gas was gas) enters the thermoregulating valve, where the pressure of the freon decreases. As a result of this, Freon evaporates, and a gas.liquid cold mixture enters the evaporator (Freon becomes cold during evaporation). The evaporator is cooled and the fan blow off the cold from it into the room. Then the gaseous freon again enters the capacitor, and at this stage the circle closes.

This fundamental scheme of the air conditioner is fair for all types. Regardless of the model, power and functionality of the system, all air conditioners are built precisely on this principle, including automobile, industrial and household.

Connection of the blocks

After the external and internal blocks of the air conditioner were installed, they must be interconnected. This is done using a copper four.wire cable. The veins must have a section of at least 2.5 mm22. The connection scheme of the air conditioner, which goes along with the device itself, is to some extent instructions. Typically, the connecting cable is laid together with the freon highway, although it can also be laid in a separate plastic box.

connecting, compressor, conditioner, network

Dedicated line

After connecting two blocks, it is necessary to connect the internal block to the network.

You can use the nearest outlet, however, given the rather high installation power, experts recommend highlighting a separate fishing line for it for a power trimmer, which will go directly to the counter.

This will remove the large load from the general line of the apartment of the apartment. The cable laying to the shield can be made on a special stroke groove or in a plastic box. Do not leave the wire open.

The shield into which the fishing line for the air conditioner power will enter (and the total fishing line for the trimmer of the apartment of the apartment) should be grounded. In this case, the cable power should be connected through an automatic of a certain power. It is calculated according to the special formula: the power of the air conditioner divided into voltage (220 or 230 V). The resulting value must be added 30 % for the reserve by power.

How to connect a single.phase asynchronous engine through the capacitor?

At industrial facilities, special problems, how to connect an electric motor, do not experience, a three.phase network is brought up there. Asynchronous electric motors work with three connected windings located around the perimeter of a cylindrical stator. A separate phase is included on each winding of the connected engine, the electric motor connection diagram provides a shift in the phase of alternating current, creates a torque, and the engines are successfully rotated.

In the case of domestic conditions at residential facilities in private houses and apartments of three.phase electric lines, single.phase networks are laid, where a voltage of 220 volts are laid. Therefore, a single.phase asynchronous engine is connected according to another scheme, a device with a launch winding is required.

Design and principle of operation

Connect the electric motor through the capacitor due to the fact that one winding on the 220 V electric motor status creates a magnetic field that compensates for its impulses due to the change in polarity with a frequency of 50 Hz. In this case, the engine is buzzing, the rotor remains in place. To create a torque, make additional connection of launch windings, where an electric shift in phase will be 90 ° in relation to the working winding.

The design of an asynchronous single.phase electric motor

Do not confuse the geometric concepts of the angle of location with an electric phase shift. In the geometric measurement, the winding in the stature is placed opposite each other.

To implement this technically, the design of the electric motor provides a large number of mechanical parts and the components of the electrical circuit:

  • stator with the main and additional winding;
  • short.closed rotor;
  • Born with a group of contacts on the panel;
  • capacitors;
  • centrifugal switch and many other elements shown above in the figure.

Consider how to connect a single.phase engine. In order to display the phases, the capacitor is consistent in the start winding, when connecting a single.phase asynchronous electric motor, the circular magnetic field leads in the rotor of the current. The totality of the strength of fields and currents create a rotating impulse attached to the rotor, it begins to rotate.

Connection schemes

Model connection options via the capacitor:

  • a single.phase engine connection diagram using a starting capacitor;
  • connecting the electric motor using the capacitor in working mode;
  • Connecting a single.phase electric motor with launch and working capacitors.

All these schemes are successfully used in the operation of asynchronous single.phase engines. In each case there are advantages and disadvantages, consider each option in more detail.

Scheme with a start.up capacitor

The idea is that the capacitor is included in the circuit only when starting, a starting button is used that open the contacts after promoting the rotor, it begins to rotate by inertia. The magnetic field of the main winding supports rotation for a long time. As a short.term switch, buttons with a group of contacts or relay are placed.

Starting condenser connection diagram

Since the short.term connection of a single.phase engine through the capacitor provides a button on the spring, which when release open the contacts, this makes it possible to save, the wires of the starting winding are made thinner.

To exclude an interval short circuit, use the thermallane, which when a critical temperature is reached, it turns off an additional winding.

In some designs, a centrifugal switch is placed, which, when a certain speed of rotation is reached, opens the contacts.

Connections, centrifugal switch to the rotor shaft

Diagrams and design of the speed of rotation and preventing overload of the electric motor on the machine can be different. Sometimes a centrifugal switch is installed on the rotor shaft or on other elements rotating from it with a direct connection, or through a gearbox.

Under the influence of centrifugal forces, the load pulls the springs with the contact plate, when the installed rotation speed reaches the contacts, the relay switch de.energizes or gives a signal to another control mechanism.

There are options when a thermal relay and a centrifugal switch are installed in one structure. In this case, the thermal relay turns off the engine when exposed to a critical temperature or the efforts of the extending cargo of the centrifugal switch.

Options for condenser connection scheme

Due to the features of the characteristics of the asynchronous engine, the capacitor in a circuit of an additional coil distorts the magnetic field lines, from a round shape to elliptical, as a result of this, power loss increases, the efficiency is reduced. Starting characteristics remain good.

Scheme with a working capacitor

The difference between this scheme is that the capacitor after starting does not turn off, and the secondary winding throughout the work with the pulses of its magnetic field unwinds the rotor. The power of the electric motor in this case increases significantly, the shape of the electromagnetic field can be tried to bring closer from the elliptical shape to a round selection of capacitor capacitance. But in this case, the moment of starting is longer in time, and the starting currents are greater.

The complexity of the circuit is that the capacitance of the capacitor for aligning the magnetic field is selected taking into account current loads. If they change, then all the parameters will not be constant, for the stability of the shape of the magnetic field lines, several capacitors with various containers can be installed.

If you include the corresponding container when the load changes, this will improve the working characteristics, but significantly complicates the scheme and operation process.

Combined circuit with two capacitors

The best option for offering working characteristics is a scheme with two capacitors. launch and working.

The working capacitor is constantly connected in the circuit of the windings, the starting through the start switch is closed for a short time

Installation and selection of components

The capacitors have considerable dimensions, so they are not always placed in the inside of the boron (the camshaft on the electric motor body).

How to connect an electric motor with unknown characteristics?. Electroly help

Most often, a single.phase network of 220 V was brought to our homes, plots, garages. Therefore, equipment and all homemade do make so that they work from this power source. In this article, we will consider how to pashingly make a single.phase engine connection.

Asynchronous or collector: how to distinguish

In general, you can distinguish the type of engine by the plate. the nameplate. on which its data and type are written. But this is only if it was not repaired. After all, under the casing can be anything. So if you are not sure, it is better to determine the type yourself.

This is how the new single.phase condenser engine looks like

How collector engines are arranged

You can distinguish asynchronous and collector engines by structure. Collector has brushes. They are located near the collector. Another mandatory attribute of the engine of this type is the presence of a copper drum divided into the section.

Such engines are produced only single.phase, they are often installed in household appliances, as they allow you to get a large number of revolutions at the start and after acceleration.

They are also convenient in that they can easily change the direction of rotation. you only need to change the polarity. It is also easy to organize a change in the speed of rotation. a change in the amplitude of the supply voltage or the angle of its cutting off.

Therefore, such engines are used in most of the household and construction equipment.

Disadvantages of college engines. high noise at large speeds. Remember the drill, corner grinder, vacuum cleaner, washing machine, etc.D. Noise when they work is a decent. At low speeds, collector engines are not so noisy (washing machine), but not all tools work in this mode.

The second unpleasant moment. the presence of brushes and constant friction leads to the need for regular maintenance. If the toxicer is not cleaned, pollution by graphite (from erasing brushes) can lead to the neighboring sections in the drum will connect, the motor will simply stop working.

Asynchronous

The asynchronous engine has a starter and a rotor, it can be one and three phase. In this article we consider the connection of single.phase engines, therefore we will only talk about them.

Asynchronous engines are characterized by a low level of noise during operation, therefore they are installed in a technique whose noise is critical. These are air conditioners, split systems, refrigerators.

There are two types of single.phase asynchronous engines. bifiral (with launch winding) and condenser.

The whole difference is that in bifile single.phase engines, the launch winding works only until the engine is accelerated.

After it is turned off by a special device. a centrifugal switch or a start.up relay (in refrigerators). This is necessary, because after overclocking it only reduces the efficiency.

In condenser single.phase engines, the condenser winding works all the time. Two windings. the main and auxiliary. are shifted relative to each other by 90 °. Thanks to this, you can change the direction of rotation. The capacitor on such engines is usually attached to the case and on this basis it is easy to identify.

You can more accurately determine the bifolar or condenser engine in front of you by measuring windings.

If the resistance of the auxiliary winding is less than twice (the difference can be even more significant), most likely, it is a bifolar engine and this auxiliary winding is launching, which means that the circuit has a switch or a starting relay in the diagram.

In condenser engines, both windings are constantly in operation and connecting a single.phase engine is possible through a regular button, toggle switch, automatic machine.

With a launch winding

To connect the engine with the start winding, you need a button in which one of the contacts after turning on is opened. These opening contacts will need to be connected to the launch winding. There is such a button in stores. this is PNVS. Her average contact closes at the time of retention, and two extreme ones remain in a closed state.

The appearance of the PNVS button and the state of contacts after the “Start” button is released “

First, using measurements, we determine what kind of working winding, which is the starting. Typically, the output from the motor has three or four wires.

If there are four conclusions, they call in pairs. Find two pairs. The one in which the resistance is less. the working one, in which there is more. starting. After that, connect one wire from the starting and working winding, display the general wire. Total three wires remain (as in the first version):

With these three wires and we work further. we are executed to connect a single.phase engine.

We connect all three wires to the button. It also has three contacts. Be sure to “put the starting wire“ put on average contact (which is closed only for the time of starting), the other two. to the extreme (arbitrarily).

We connect the power cable (from 220 V) to the extreme input contacts of the PNVS, connect the average contact with a jumper with the worker (pay attention! not with the general). That’s the whole circuit of turning on a single.phase engine with a launch winding (bifolar) through the button.

Condenser

When connecting a single.phase condenser engine, there are options: there are three connection schemes and all with capacitors. Without them, the motor is buzzing, but does not start (if you connect it according to the scheme described above).

Single condenser engine connection diagrams

The first scheme. with a capacitor in the supply circuit of the starting winding. are well launched, but during operation the power is far from nominal, but much lower.

The switching circuit with the capacitor in the connection circuit of the working winding gives the opposite effect: not very good indicators when starting, but good working characteristics.

Accordingly, the first scheme is used in devices with heavy starting (concrete mixers, for example), and with a working condenser. if good working characteristics are needed.

Two condenser circuit

There is another option for connecting a single.phase engine (asynchronous). install both capacitors. It turns out something between the options described above. This scheme is most often implemented.

Electrician in residential premises

Having determined where the connection point should be and by choosing the model, you can proceed to the installation. First. make sure that the power grid is de.energized. This requires an indicator. The cross section of the wire is at least 2 mm. Do not use aluminum wiring, with high power it heats up, cannot be directly connected to the metal elements of electrical circuits. This will lead to the oxidation of contacts. Use copper electrical wires. For wooden walls, it is allowed to install only overhead or external models.

The actual height of the outlet must comply with the accepted norms. You need to correctly measure the distance from the floor, ceiling and windows. As a reference point, use the center, not the boundaries of the circuit. When stroobiting, the depth and width should be larger than the dimensions of the cable per 1-2 mm.

For work, you need a trobores, a drill-poorator, a nozzle for the formation of a niche in the wall, isolet, and heat-assigned tape. During the processing of concrete or brick surfaces, there will be a lot of dust, it is recommended to close the furniture with a film or temporarily remove from the installation zone.

Installation procedure

  • Make strokes and hole.
  • Install the wiring.
  • Clean the ends of the wires by 0.5-1 cm.
  • For hidden models, weaken the fixation screws in the mounting opening of the wall, for overhead and external ones. remove the back cover.
  • Fix the cleaned wires (phase, zero, grounding) in the corresponding terminals.
  • Check the reliability of the connection.
  • Install the body in the wall, fix.

By the way, we recommend a useful article about home plants that must be grown at home to clean the air.

Using an indicator screwdriver, check the presence of an electric circuit. The case should be reliably attached to the wall, with possible sharp jerks of the fork, it remains in place.

Drainage

Pay attention. the drainage hose should be located below the freonomagistral

Fix the internal block on the mounting plate.

Connect the drainage hoses of the air conditioner.

To increase, many use the usual metal-plastic pipe D-16mm. The factory drainage tube is broken off and metal.plastic is inserted into it, to sealing from above the compound with electrical tape.

2002 Chevy Silverado AC Relay & Fuse, Circuit Explained

However, inside the metal.plastic, after time, a fungus may form, which will not allow water to leave quickly enough.

Therefore, other installers use only corrugated pipes as drainage.

In addition, it is corrugated drainage that allows you to connect directly to the bath without additional compounds.

How to connect air conditioning correctly

When users ask this question, then two different meanings can imply:

You need to know that there is an “inter.block” connection of the wires and the connection of the “power” of the device. In this article we will analyze both of these issues.

In addition to the fact that the blocks must be correctly placed and fixed, it is also necessary to correctly connect them among themselves. In general terms, so that the split system works:

  • Display drainage where it is required (most often on the street, very rarely in the sewer). The internal block has a drainage conclusion that needs to be “built up” and removed along with the main communications;
  • Connect power to the desired block (this will be the answer to the second question);
  • Connect two blocks with communications. Below we consider this in more detail.

What communications are meant, and what exactly needs to be connected:

  • thin copper tube (in thermoflex);
  • thick copper tube (in thermoflex);
  • Interlock cable. Most often this is a five.core cable. The essence of its connection is that the wires are connected to the external block to the same terminals as the internal block. Typically, the instructions for the air conditioner have a detailed description. The figure below shows the connection of the wires of one air conditioner;
  • Rarely in the kit with the air conditioner is an additional interblock (two.core) wire. It will also need to be connected, too.

There are two main ways to connect the air conditioner to the mains

Inverter air conditioners most often have a network connection to the external unit. On/OFF air conditioners (non.inverter) are most often connected to the network through the internal unit. In this case, the inner block may have a wire with a fork or without it. The wire has three veins-yellow-green (“earth”), blue (“zero”), brown (“phase”).

The figure shows the connection of the external unit. The left block is an “interblock” connection (4 wires in this case). A three.phase air conditioner power supply is connected to the right block (Power Supply.

It is important for all air conditioners: if the interior unit of the split system does not have a wire with a fork, then when connecting the power (to the desired block), you must follow the phasing. The zero wire must be connected to the terminal “N”, and the phase to the terminal “l” or “p”.

you must follow the phasing. The zero wire must be connected to the terminal “N”, and the phase to the terminal “l” or “p”. I work as a ship electrician. Maintenance and repair of any refrigerator equipment, my direct responsibilities. Repeatedly I had to install household air conditioners on ships, including modern inverter. All air conditioners I have set without problems for several years. In this regard, I am embarrassed to ask what phasing we are talking about? There is usually no zero on ships, and the network is 220 or 110 volts of two.phase.And what to observe?

Hello! Unfortunately, we have no experience on ships. And when connected in domestic conditions, we adhere to modern standards (GOST R 50462-2009 (IEC 60446: 2007) and the manufacturer’s recommendations. But now we will know that the air conditioner works without problems from a two.phase network.

A network for household needs, 220 or 110 volts, as a rule, not two phase, but single.phase. Just at ship power plants, as well as on mobile, there is no grounded zero.Therefore, there is no need to follow the phasing.

Here, everyone uses GOSTs without understanding why they are needed. Why are they and do not know what to do when it is impossible to follow them. And here everything is simple, there is a regular alternating current on the network. Both wires are absolutely the same and equivalent, and they would not differ in anything If one of them would not be grounded. This is zero. In the second wire in this case, the full voltage of the network will be relative to the earth. It is this wire that is called the phase. And if we mount switches, bags, they must turn off the phase wire to relieve voltage relative to the ground. In this case, when you take your hands for a slightly breaking through the disabled device, you will not hit the current. And if you remove zero, then on the device there will be voltage relative to the ground. On the ship, the concept of phase and zero cannot be, unless, of course, connect one of the wires to the ship’s hull. What will be the voltage between each of the wires and the body who knows it depends on the leakage currents on the case on each of the devices. It can be imagined that two resistors were turned on between the network wires, and the middle was connected to the body. In terms of safety, if something can hit the current, turn off both wires with bags and switches. And in the air conditioning itself, the power supply and off will be carried out through the wire marked as phase.

Hello, I studied for an ordinary bottle.off convictor there is one cable of Shol from the interior to the external unit and right now I pay attention that two cables come out of the second cable of the second cable from Chevo ?! And where the guys go where?!

Hello! In most household split systems, power is suitable for the inner block-in this case, one inter-block cable is coming from the inner block to the external unit. In some models, the power system is connected to the external unit-in this case, from the external unit to the internal, one inter-block cable is the second cable to the external unit goes from the current source. In addition, there is an additional two.core cable between the blocks for the temperature sensor (for example, Panasonic air conditioners often have such a cable).

Greetings, my power should come to the external unit, but when the wiring was done, they brought it to the internal. Nothing if I feed me from the internal, the maples on the external are still swarm?

Good afternoon! If the terminals in the outer block are patented, then you can connect to the internal.

General Aug25uar air conditioning, what can happen to it if the three conductors (3F) of the Earth are connected and fed, but the zero is not connected. 2. What will happen if the phasing is broken?

Good afternoon! one. The air conditioner will not work. Nothing else will happen if you do not climb into it and do not turn on the remote control. 2. If the phasing is broken, the compressor may not turn on and give an error. Then you need to change any two phases to each other.

Help in the situation with connecting the air conditioner Artel 18. When moving, the cable labeling that goes to the outer block fell out. 2 cables for 2 gyms. One cable in the thickness of the color on the veins is brown and blue. And the other brown and blue lived thinner than the color. There is a scheme on the cover, but it shows internally a branching. The air conditioner is installed, vacuumed with a vacuum pump (the vacuum arrow did not change within 2 hours after turning off the pump), tested for tightness with a manometric station. The problem is to find out which cable and Zhili where to connect? Thanks in advance.

Good afternoon! It is necessary to find the wire connection diagram to the external unit on the case or on the lid of the external unit. According to it, you need to connect the wires coming from the inner block (the colors of the wires to the terminals of the internal block should approach the similar designations of the terminals of the external unit). If the scheme is not found, it will be more difficult to understand without minimal knowledge of electrical equipment. You need to remove the top cover of the outer block, look where the wires from the pads are suitable. Usually this: N from the inner block approaches the blue wire of the external, “Earth” of the inner unit approaches the yellow-green external, “1” of the internal one approaches the first terminal with a brown wire on the outside (but there are other colors. ). The remaining wires must be viewed visually on the blocks and circuit. often the “3” of the internal unit goes to control the fan of the external unit, and “4” the internal goes to control the four.way valve of the external unit.

How to connect air conditioning correctly

How to connect air conditioning

When users ask this question, then two different meanings can imply:

You need to know that there is an “inter.block” connection of the wires and the connection of the “power” of the device. In this article we will analyze both of these issues.

In addition to the fact that the blocks must be correctly placed and fixed, it is also necessary to correctly connect them among themselves. In general terms, so that the split system works:

  • Display drainage where it is required (most often on the street, very rarely in the sewer). The internal block has a drainage conclusion that needs to be “built up” and removed along with the main communications;
  • Connect power to the desired block (this will be the answer to the second question);
  • Connect two blocks with communications. Below we consider this in more detail.

What communications are meant, and what exactly needs to be connected:

  • thin copper tube (in thermoflex);
  • thick copper tube (in thermoflex);
  • Interlock cable. Most often this is a five.core cable. The essence of its connection is that the wires are connected to the external block to the same terminals as the internal block. Typically, the instructions for the air conditioner have a detailed description. The figure below shows the connection of the wires of one air conditioner;
  • Rarely in the kit with the air conditioner is an additional interblock (two.core) wire. It will also need to be connected, too.

There are two main ways to connect the air conditioner to the mains

  • A fork in a socket. In this way, small household conditioners are connected by cooling power up to 4 kW. Other electrical devices should not be included in the same outlet;
  • Through the machine. Cooling air conditioners more than 4 kW must be connected via an automatic. It is also advisable to connect all inverter air conditioners through the machine so that the phasing is observed.

Inverter air conditioners most often have a network connection to the external unit. On/OFF air conditioners (non.inverter) are most often connected to the network through the internal unit. In this case, the inner block may have a wire with a fork or without it. The wire has three veins-yellow-green (“earth”), blue (“zero”), brown (“phase”).

The figure shows the connection of the external unit. The left block is an “interblock” connection (4 wires in this case). A three.phase air conditioner power supply is connected to the right block (Power Supply.

It is important for all air conditioners: if the interior unit of the split system does not have a wire with a fork, then when connecting the power (to the desired block), you must follow the phasing. The zero wire must be connected to the terminal “N”, and the phase to the terminal “l” or “p”.

Connecting the air conditioner to the mains

Every air conditioner consists of two functionally dependent parts: a cooling line that provides the process of cooling the air and the electric system, which controls the elements of the contour. Thus, for the operation of the climatic device, you need to perform not only installation work, but also connecting the air conditioner to the electric line.

General recommendations

It must be borne in mind that the electrical circuit of the connecting split systems used for household devices is fundamentally different from the similar connection of industrial products mounted in stores and offices. Basically, household wall air conditioners have a single.phase electric system and connect them through a socket.

The connection of any air conditioning installation is carried out in several stages, while they must be adhered to without fail.

Reusing an air conditioner compressor

The main requirements regarding the connection of the split systems are as follows:

  • The use of only copper wires with a certain cross section;
  • Mandatory grounding in electrical panel;
  • Use from overloads in the network of special automatic devices;
  • Application of the apparatus leveling voltage (stabilizer).

Thanks to the use of copper wires and protective machines, an increased load provided on an electric fishing line for the air conditioner trimmer will not allow to fail the entire electrical wiring of the house. It must be borne in mind that when laying cables through the walls, they must be laid in a corrugated sleeve.

Air conditioning is a sensitive device. In this regard, it requires an appropriate electric line to ensure normal operation.

Self.connection of the air conditioning inter.block cables

After installing the external and indoor modules, they must be connected with each other with a cable, while the connection guide is a circuit for connecting the air conditioner to the mains.

Electric cables are allowed to be carried out in one train with a pipeline, so they can be laid and separately in the cable channels. When co.laid with the tubes, the wires must be laid in the corrugation. After the modules are connected to each other, you need to connect the indoor module to the electrolyte.

The planned connection of the device to the electric line provides for the acquisition of power from both from the outlet, near the located and from a separate line. Everything will depend on the power of the air conditioner, but in any case, the best solution is a separate power supply.

connecting, compressor, conditioner, network

Such a connection will not overload the existing home scheme and will allow you to separately connect the internal module. When conducting a cable from the outer block along the wall, a large role from the closure of the wires is played by protecting them from the effects of external precipitation.

Connecting air conditioner to electrolyte

When installing climatic devices, two main methods are used, through which the air conditioner is connected:

The original option is good for most household appliances, and in this way they are usually introduced into the work.

With an outlet for air conditioning

With this connection method, it should be, however, to be aware that the air conditioner can only be included in the outlet if:

  • The climatic device has a fairly small performance;
  • A fishing line for a trimmer in the house is made of a copper wire with a cross section of at least 2.5 mm;
  • There are no other energy.intensive devices on one section with a split system;
  • The connected fishing line for a trimmer is equipped with a protective device at least 20 A.

If the outlet is located at a large distance from the apparatus, then it is better to make a stroke in the wall and lay a cable in a corrugated pipe in it, and then install an enhanced outlet in the right place.

The socket in any case must correspond to a certain current: if the power is 1 kW, then the outlet is installed on 8-10 A; from 1 to 2.5 kW-15-17 A; from 3 to 4.5 kW. 20 A; from 4.6 to 5.6 kW. at least 25 A.

Direct connection to the network

Experts recommend using a safer and tested method of connecting the air conditioner: individual line. This guarantees stable operation of the equipment. A separate cable makes it possible to place modules in convenient, in terms of creating coolness and interior, places.

Basic conditions for a separate network:

  • Independent ground circuit;
  • compliance of the cross section of the vein recommendations of the manufacturer;
  • The wire should be copper;
  • The network is protected by a machine or other protective shutdown device;

Connecting climate technology does not tolerate errors, so if there is no confidence in independent, competent connection of split systems, it is better and more reliable to entrust this matter to specialists.

What cable is needed to connect a split system

To be guaranteed to make a high.quality connection of the air conditioner, you must use the wire corresponding to the manufacturer’s conditions. As a rule, household appliances of this row in power are connected by a wire with a cross section from 1.4 to 2.5 mm. over, the current is allowed at the same time up to 17 A.

If the distance is less than 10 meters, then it is allowed to lay the wire with a section of 1.5 mm. At a greater distance, a cable is used for air conditioning with an increased diameter, and the use of wires with aluminum residential is prohibited.

There are two methods of laying wires for split systems:

  • The collected wires are laid in a plastic corrugation and then fixed with clamps in the strobes. Then the grooves are closed with gypsum. If necessary, gypsum can be easily opened.
  • The leaf of the wires is placed in a special corrugated sleeve, then laid in a plastic channel fixed on the wall.

For single.phase connection, a three.wire wire is used, and for a three.phase. a five.core cable. It is forbidden to install power wires near the heating pipes or a gas pipeline. The distance between them should be at least one meter.

Do I need a circuit breaker or RCD

To understand the essence of the issue, you need to understand in detail the purpose of these protective devices:

  • Regulations for design and construction, as well as PUE and GOST R 50571.8 reads: Connection of the RCD depends on the danger of electric shock and the type of the on the rosette on. It follows that not all sockets for air conditioning are turned on through the RCD.
  • These RCDs are placed to protect people from electric shock when poor isolation. But all the boxes of the split modules are made of plastic, that is, from a person’s direct touch to the body, he will not be able to suffer.
  • The peculiarity of protective shutdown devices is that they cannot protect a person from a short circuit: just an RCD will not have time to disconnect. Indeed, from the laws of physics it is known that the current rate in the conductor is 300 thousand. km/s, and the operation time of any protective device, including the RCD, is 0.02-0.03 seconds.
  • The circuit breaker is a protective device for wires, which are selected by equipment power. And in the case of an increased load on the network or short circuit, the machine operates and saves one or another device from overheating and failure.
