Today, many people are interested in circuit diagrams for split systems, for heating boilers of various brands and models, in this article we will not specify in detail in which cooling devices this or that circuit is used, but we will break them down by microchip manufacturers

As it turned out, the circuit diagrams for controlling air conditioners and heating boilers are almost identical, i.e. look like twins and brothers.

The basis of the so-called similarity is a microchip, or a microcircuit that sets the algorithm for one or another signal control process both on boilers and on splits ...

Why is it necessary? Having at hand a circuit diagram with detailing and voltages at control points, you can easily determine the faulty element of the control board not only of a split system, but of almost any gas, diesel or combined boiler of a heating and hot water supply system.

Boiler control board, split

I’ll tell you a secret that if you order the original boiler control board, split separately, you will get a very impressive amount of several thousand rubles, but ...

this is not the most important thing, money, the price of the issue of replacing the board today, few people are scared and stopped, in the end it is possible to completely replace the device ...

But, the time factor ... as a rule, split systems break down in the summer in the very heat and heat, and boilers and other heating devices of a private house break down, respectively, in the winter during intensive operation, this is called Shutdown.

And, if you have a circuit diagram, you can in one day determine the malfunctions of one or another algorithm, repair the control board and restore the device to working capacity.

This is especially true for boiler equipment, in order not to freeze the heating system at home, it is necessary to act quickly and efficiently.

Is it possible to make the connection yourself (at home) without involving specialists and how to do everything right?

The main difficulties, in my opinion, arise when connecting the outdoor and indoor units copper pipes(purchase of these tubes (I have not seen them anywhere in the markets. maybe I did not look carefully) and their flaring).

Maybe I missed the main points, I think in the process of discussion with the whole world, we will figure out what's what and help install the air conditioner.

By the way, I forgot to say that the LG G07LH air conditioner will be installed in a living room with an area of ​​15m2, the outdoor unit will be placed only on the loggia (because it is on the 2nd floor and there is a possibility of its theft).

That seems to be all where to start, probably with the purchase of the necessary additional components:

1. Wire El. section 1.5mm2;

2. Copper tube 3.8v (for refrigerant connection) (diameter 9.52) - never seen on the market;

3. Copper tube 1.4v - (for connecting condensate) (diameter 6.35) - never met in the markets;

4. Rubber pipes for the room copper pipes ok (used as insulators);

5. Vinyl electrical tape;

6. Branch pipe with a tube (for installation in a wall);

11. Plug for connecting to El. socket.

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

General scheme of the air conditioner

The whole system is built on the ability of substances to absorb heat during evaporation and release it during condensation. Such an air conditioner scheme is incorporated into the operation of a modern split system. The main substance inside the closed system of the device is freon. Being able to change it state of aggregation by changing the temperature and pressure, we can cool the radiator and drive air from the street through it.

But first, let's get acquainted with the main elements of the split system. The scheme and principle of operation of the air conditioner involve the use of two blocks: outdoor and indoor. What are they needed for?

outdoor unit

This unit is installed outdoors and mainly serves to cool superheated freon (it does not take air from the street, the air conditioner is used to cool the air in the room. Ventilation units are used to take in street air). It consists of the following nodes:

• Fan.
• Capacitor. In this part, freon is cooled and condensed. The air that passes through the condenser is heated and vented outside.
• Compressor. The main element of the air conditioner, which compresses freon and circulates it throughout the circuit.
• Control block. It is usually used in outdoor units of inverter systems. In conventional air conditioners, all electronics are most often located in the indoor unit.

• 4 way valve. It is used in models that can work for heating (most modern air conditioners). This element, when the heating function is activated, changes the direction of the refrigerant flow. As a result, the outdoor and indoor units change places: the internal one works for heating, the external one - for cooling.
• Various fitting connections, through which copper pipes are connected between the indoor and outdoor units.
• Coolant filter. Installed in front of the compressor in order to protect the latter from dirt, which during installation can enter the system.

indoor unit

It includes elements:

• Front panel through which air enters. It is easily removed so that the user can get to the filters.
• The coarse filter is a common plastic mesh, which traps coarse dust (for example, animal hair, fluff, etc.). This mesh should be cleaned once a month.
• Filter system consisting of carbon, antibacterial, electrostatic filters. Depending on the model of the air conditioner, some filters may not be available at all.

• The fan for circulation of pure air in the room - cold or warmed up.
• Evaporator. It is a radiator where ice coolant enters. This radiator is heavily cooled by freon, and the fan drives air through it, which instantly becomes cold.
• Blinds for adjusting the direction of air flow.
• The indicator panel shows in which mode the air conditioner is operating.
• Control fee. It contains the central processing unit and the electronics unit.
• Fitting connections - pipes connecting the indoor and outdoor units are connected to them.

The air conditioner circuit is simple and logical, but some users do not understand why two units are needed? After all, you can take warm air from the room and drive it through the air conditioner, cooling it. But not everything is so simple: you cannot produce cold without producing heat. The heat needs to be vented out. For this purpose, a two-block system is ideal. There are also other systems, such as single-block. There, the heat is removed to the outside through a special air duct, brought outside the apartment.

Detailed scheme of the air conditioner

Now that you know the basic elements, you can consider in more detail the scheme of operation of this system. So, when the cooling mode is activated from the control panel, the compressor turns on in the system. It pressurizes and drives the gas through the radiator. Having passed the radiator (in the outdoor unit), the gas becomes liquid and hot (if you remember, it releases heat during condensation).

Now the hot liquid freon (which was gas before the radiator) enters where the freon pressure drops. 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 blows the cold out of it into the room. Then the gaseous freon enters the condenser again, and at this stage the circle closes.

This circuit diagram air conditioner is valid for all types. Regardless of the model, power and functionality of the system, all air conditioners are built exactly on this principle, including automotive, industrial and household ones.

Connecting an air conditioner

The installation scheme of the air conditioner is simple, but the installation itself is quite complicated. Only specialists who have the appropriate equipment can produce it. The whole difficulty lies in the installation of the outdoor unit and the pumping of freon inside. It is also required to make a huge hole in the wall, and if the house is panel, then the complexity of the work increases.

As for the connection to the mains, it is enough just to connect the indoor unit of the device to the outlet, nothing more. But the power conditioner connection diagram is a document that shows the location various components and information for service centers. He is in more interested in engineers who are engaged in the repair and connection of equipment. In the context of this article, it is impossible to give a single scheme for connecting an air conditioner, since it is for various models may be different.

Connecting blocks

After the external and internal units of the air conditioner have been installed, they must be connected to each other. This is done using a four-core copper cable. The cores must have a cross section of at least 2.5 mm 2. The air conditioner connection diagram that comes with the device itself is to some extent an instruction. Typically, the connecting cable is laid along with the freon line, although it can also be laid in a separate plastic box.

Leased line connection

After connecting the two units to each other, you need to connect the indoor unit to the network. You can use the nearest outlet, however, given the rather high power installation, experts recommend allocating a separate power line for it, which will go directly to the meter. This will remove a large load from the common line of the electrical system of the apartment. Cable laying to the shield can be made through a special groove or in a plastic box. Don't leave the wire open.

The shield into which the power line of the air conditioner (and the general line of the electrical system of the apartment) will enter must be grounded. In this case, the power supply of the cable must be connected through the automatic certain power. It is calculated using a special formula: the power of the air conditioner divided by the voltage (220 or 230 V). To the value obtained, you need to add 30% for the power margin.

Connection to the general power supply system of the apartment

Connecting the device to a conventional outlet that belongs to a common power line is possible only if your air conditioner is not powerful and will not create a large load on the network. When the power consumption of the air conditioner is 1 kW or less, it can be connected to a conventional outlet. Typically, models designed for cooling 20 square meters have such a capacity.

The device and principle of operation of the split system air conditioner

Many of us use air conditioners at home or at work to cool the air in our rooms. But not everyone knows how they function. The purpose of this article is to explain the device and principle of operation of a split system, which are most often found in our Everyday life.

Household air conditioner device

Modern split-system is divided into two parts - outdoor and indoor units. Each of them performs its function and contains a set of appropriate equipment. Inside the case of the outdoor unit there is a heat exchanger - a condenser, a fan designed to drive air through it, and a compressor - a pressure supercharger. Of the smaller, but no less important functional elements, a dehumidifier, an expansion valve and copper connecting pipes should be distinguished. In addition, the device of this node provides for power supply from the mains, for which it has the necessary electrical elements, as well as automation tools.

Note. In the case when the design provides for the operation of a split system for heating, a four-way valve with an electric drive, a compressor heater and a condensing pressure regulator are additionally installed in the outdoor unit.

Inner part the air conditioner, in addition to the housing, contains a heat exchanger - an evaporator with a centrifugal fan, filter elements, louvers for directing the air flow and a condensate collection tray. Between the indoor and outdoor units, 2 lines for the refrigerant are laid, it moves through a pipe with a large diameter in the form of a gas, with a smaller one - in a liquid state. The figure below shows the device of a split system with an indication of the main elements:

1 - compressor; 2 - four-way valve for switching between winter and summer modes; 3 - electronic block; four - axial fan; 5 - heat exchanger - condenser; 6 - lines for the refrigerant; 7- centrifugal fan; 8 - heat exchanger - evaporator; 9 - coarse filter; 10 - fine filter.

Principle of operation

Split - system, like any refrigeration machine, is very different high efficiency. For example, a chiller that consumes 1 kW of electrical power has a cooling capacity of approximately 3 kW. At the same time, no laws of conservation of energy are violated and the efficiency of the installation is not at all 300%, as you might think.

It should be understood that the principle of operation of the air conditioner is not in the production of cold, but in the transfer of thermal energy from one place to another through a refrigerant called the working fluid.

Freon acts as a working fluid, whose boiling point is almost 100 ºС lower than that of water. The trick is that for vaporization, any liquid must receive a large number of thermal energy, its working fluid and takes away from room air in the evaporator. In physics, this energy is called specific heat vaporization.

Freon evaporated in the indoor unit through a large-diameter tube enters the compressor, which creates pressure in the split system and further, into the heat exchanger-condenser. The working fluid under pressure condenses intensively in it upon contact with the outside air, releasing previously absorbed heat into the atmosphere. Only now it is called the specific heat of condensation, with a constant amount of freon in the system, its value is equal to the expended energy of vaporization. How the described process takes place is shown by the diagram of the split system air conditioner:

After entering the liquid phase, the refrigerant passes through the dryer to separate moisture and enters the expansion valve. Here at the expense sharp increase the size of the channel (nozzle), the pressure decreases and the working fluid returns to the evaporator again for the next portion of heat.

From electrical equipment that consumes significant power, you can see two fans and a compressor in the diagram, other sources of energy consumption are negligible. That is, the 1 kW of electricity given in the example is spent only on the rotation of the axes of the fans and the compressor, freon does the rest of the work.

All other functions - for automation systems. Upon reaching set temperature in the room, the sensor sends a signal to the control unit, and it stops the compressor and fans, the process stops. Air environment the room has warmed up - and the sensor again initiates the start of the cooler, such a cyclic work in progress continuously. At the same time, inverter split systems, whose design is slightly different from conventional air conditioners, never stop the process. Such units are characterized by a smooth temperature change and a quiet operation of the compressor.

Note. During intensive heat exchange processes, the moisture contained in the air falls on the fins of the evaporator and condenser; for its collection and removal, the design of the air conditioner provides for a bath and a system of pipes.

To switch the unit to the air heating mode, the direction of movement of the working fluid is switched, as a result of which the heat exchangers change functions, the external one becomes an evaporator and takes heat from environment, and the internal one acts as a capacitor, transferring this energy to the room. To redistribute flows, a four-way valve was introduced into the circuit so that you do not have to be tricky with the compressor.

ConclusionSplit - a system like others refrigeration machines, is very economical due to the efficiency of its work. It is for this reason that they have gained wide popularity for creating comfortable conditions in buildings for various purposes.

How to connect the air conditioner to the mains with your own hands: tips from the master

Any air conditioner consists of two parts of different functions: the refrigeration circuit, which performs the function of air cooling and the electrical part that controls the devices and elements of the circuit.

This article will discuss the electrical circuit of the air conditioner, the options for connecting it to the power supply and how to properly connect the air conditioner to the mains.

What is the electrical circuit of a split system

Wiring diagram air conditioner is a document that displays the location of electronic components, their connection, as well as information for service center engineers. Everyone who is involved is more interested in the electrical connection diagram of the air conditioner, which includes the location of the main devices of the evaporator and condenser unit, terminals for connecting the units to each other and connecting the power supply.

The main elements here are:

• Compressor, with CSR outputs. The arrow shows the protection installed on the compressor winding
• Compressorcapacitor - a capacitor, with two leads connected to the windings of the compressor unit. The third terminal of the capacitor is connected to its starting winding.
• In addition, the diagram shows a fan motor and a capacitor through which two motor windings are connected.
• The diagram shows an electromagnet that controls the operation of a four-way valve.

Terminal designations in the terminal block:

1(N) is zero.

3 - Power supply to the fan motor when it is running at low speeds.

4 - Power supply to the fan motor when it is running at high speeds.

Separate terminal - ground.
Main modules and blocks:

• Power filter through which voltage is supplied to the control board.
• Control board is a control unit to which all device modules are connected.
• The compressor power relay is connected to CN 12.
• A drain pump is connected to CN6.
• The CN 5 terminal block is responsible for controlling the split system fan.
• To the terminals of CN 10, a stepper motor for controlling the louvre is connected.
• The CN 7 terminals are responsible for connecting the heat exchanger temperature sensor.
• A room temperature sensor is connected to terminals 1 and 2 of the CN15 terminal block.
• A water level sensor in the sump is connected to terminals 1 and 3 of the CN15 terminal block.
• Terminal block CN 13 of the control unit is responsible for connecting the display unit of the device.

Terminal block (marked on the board as Terminal) for connecting the evaporator and condenser units with a cable. Terminals L and N - power supply of the air conditioner from the electric line. gears. You should know what exists with connecting the air conditioner to the mains through an external unit.

With this connection, you must follow the instructions. If air conditioning equipment with a power of up to 4.5 kW is connected, then a four-core copper cable with a cross section of 2.5 mm2 must be used. With a separate power branch, a 20 A automatic machine must be installed on the shield.

Connecting an air conditioner

After that, they must be interconnected with a four-core copper cable with a core cross-sectional area of ​​at least 2.5 mm2. The connection instruction is a circuit diagram, which was discussed in sufficient detail above. The connecting cable can be laid together with the freon line, or maybe in a separate plastic box.

When laying in one strobe together with copper pipes, use a corrugated plastic tube to insulate the cable.

After interblock electrical connection connect the indoor unit to the power supply. The scheme for connecting the air conditioner to the mains involves receiving power both from the nearest outlet and from a separate line.

An ideal option for connecting a sufficiently powerful climate equipment is a separate power line. This option will not load the already existing lines of the apartment electrical system and will allow you to supply power directly to the indoor unit of the split system. The laying of the power cable from the shield to the indoor unit can be done along a grooved groove in the wall material or in a special plastic box.

The shield from which a separate power line will be drawn must be grounded. Connecting the power cable to the terminal block of the shield should be carried out only through the machine, the power of which should be calculated according to the formula: the power of the device divided by the voltage. 30% of the margin should be added to the resulting value.

It should be understood that the power cable for climate control equipment can be connected to the outlet only if:

• The air conditioner has little power.
• The house electrical network is laid with a copper cable with a cross section of at least 2.5 mm2.
• There are no energy-intensive consumers on the same branch with air conditioning.
• Supposed to be temporary.
• This branch of power supply is equipped with an automatic device with an RCD of at least 20 A.

Options for connecting an air conditioner to an existing power line

This issue could not be considered, due to the presence of sockets in the room. But, some owners of low-power climate equipment are unhappy with the stretching wire from the outlet to the consumer, often through the entire wall.

If the outlet is far enough from the air conditioner, then there is an option to connect the air conditioner to the mains through a switch. We warn you right away: this option is only suitable for low-power climate control equipment, and here's why: the terminals of a conventional switch may simply not withstand the current passing through them. As a result, heating, sparking, failure of the switch (at best) or fire.

It is better to make a groove in the wall from the existing outlet and lay the power cable through it in the corrugated pipe to the split system unit, and then mount a special outlet with a decorative overlay into the wall. The socket must withstand a certain current: if the power is 1 kW, then the socket must withstand 9-10 A; from 1 to 3 kW - 16-18 A; from 3 to 4.6 kW - 20 A; from 4.6 to 5.5 - at least 25 A. Right choice best left to a qualified electrician.

If you decide to connect the air conditioner with your own hands, then do it in compliance with all safety regulations, and in order to be completely sure that the connection process went correctly and safely for the climate control equipment and the inhabitants of the home, it is best to seek help from professionals.

Schematic diagram of connecting the air conditioner

When both units of the air conditioner are installed, it is necessary to lay the electrical wires and connect them to the network, the electrical circuit diagram of the air conditioner serves as a guide for this.

Connecting indoor and outdoor units

First you need to connect the two units of the air conditioner together. And only after that the electric cable is mounted, connecting the indoor unit to common system apartments.

The air conditioning circuit is not the same for different models. Devices for apartments are most often connected to one phase. Three phases are required to connect high power devices.

Using existing wiring

It is allowed to connect the wires of the air conditioner to the wiring in the apartment if the electrical circuit allows it and:

• Low power device;
• Window or mobile;
• If the network is designed for high loads;
• As a temporary solution to the problem;
• A separate line has been allocated for the air conditioner, to which powerful appliances are not connected.

In this case, the connection diagram of the air conditioner is the main document that you should be guided by.

It is forbidden to connect to an already prepared electrical network if:

• The network is laid with aluminum wires;
• Wires of small section;
• There is no grounding and special protective systems;
• Wires are old or damaged.

If the device is connected to an already prepared network, it is necessary to install a differential machine and a mechanism emergency shutdown.

The schematic diagram provides for the installation of an automatic machine at least 20 A at the wire connection point.

Separate power line

This type of connection has many advantages.

The device is not subjected to power surges, overloading the network itself is impossible. A special wire to the device can be brought to any point in the room.

The connection diagrams of the outdoor and indoor units, as well as the electrical circuit diagram of the air conditioner are printed on the back side of one of the units of the device.

Power Line Options:

• The line must be equipped with an automatic machine;
• Be sure to have grounding;
• Only copper wires are laid;
• The cross section of the wire must be at least 3 by 2.5.

When connecting the air conditioner to the electrical network, you should definitely resort to the user manual, which has a diagram electrical connection this type of air conditioner.

If a separate wiring goes to the device, it is not necessary to mount a differential machine and an emergency shutdown mechanism for the indoor unit.

The scheme of the air conditioner - everything is very simple

Greetings to all visitors and readers of the Air Conditioner site! Today I will talk in detail about the process of "getting" cold from air conditioner - you will learn how the pressure and temperature of freon change.

The whole point is that when compressed, freon heats up very much, then it gives off heat - this happens during outdoor unit. After that, the refrigerant enters the indoor unit, where it expands and “takes” heat from the room.

The figure shows the freon temperature: in red - the hottest state (approximately 65˚C), in blue - the coldest state (approximately 2˚C).

The principle of operation of the split system

Only 4 elements are involved in heat transfer. For the starting point, we take the compressor, which circulates the refrigerant between the blocks:

The process is repeated cyclically.

In order for the air conditioner to work for heating, it is necessary, as it were, to swap the evaporator and condenser. This function in "splits" is performed by the so-called 4-way valve. It redirects the movement of freon in the considered chain.

For a better understanding of the split system device, read the corresponding article. And be sure to watch the video, which demonstrates the entire cooling process very well.

The device and principle of operation of the air conditioner

The device and principle of operation of various air conditioners are similar. These systems have a common structure and purpose. The difference between them is only in the location of the system in the house and the external form of the device.

Air conditioner device

All air conditioners consist of the following parts:

• fan;
• throttle;
• capacitor;
• compressor;
• evaporator.

The compressor compresses the freon and forces it to circulate in the system. The condenser is used to convert freon from gas to liquid. It is usually located in the outdoor unit. The evaporator, on the contrary, causes liquid freon to turn into gas. Its action is opposite to that of a capacitor. The throttle lowers the freon pressure, and the fans cool the system.

This is how every such device works. The principle of operation of a floor air conditioner does not differ from the principle of operation of a wall or ceiling air conditioner.

System operation

All parts of the air conditioner (with the exception of fans) are interconnected using thin copper tubes. In some devices, the tubes are made of aluminum. A coolant circulates through the tubes inside the air conditioner (most often it is freon). The coolant takes either gaseous or liquid form. Fans protect the system from overheating.

When freon vapor enters the compression hole, it has a temperature of about 10-15 degrees. Its pressure is 4-5 atmospheres. The compressor compresses the refrigerant, the pressure increases 5 times, and the freon temperature rises to 90 degrees.

Very hot freon enters the condenser. There it cools, releasing heat, and smoothly turns into a liquid state. Next, the freon passes the throttle and enters the evaporator. Here the liquid agent is mixed with the gaseous agent. Evaporating, it creates cooling. After that, the freon enters the compressor again, and the cycle closes. This is what it looks like simple circuit how the air conditioner works.

Varieties of air conditioners

There are several types of air conditioners, although the principles of operation are the same for all. According to the type of air intake, such systems can be conditionally divided into:

• supply;
• recirculation;
• air conditioners with recovery function.

Recirculation systems work with internal air, supply systems use external air masses, and systems with a recovery function use both of these methods.

In addition to this differentiation, there is another division of air conditioners:

1. Monoblock - systems consisting of one block, in which all functions are combined. They are very easy to operate, easy to repair and serve long time. Such air conditioners are unpretentious. Their only disadvantage is their high cost.
2. Split systems consist of two separated blocks. One of them is placed outside the building, and the second indoors. Both parts of the system are connected by a tube through which freon circulates. The fan and evaporator of such an air conditioner is located in the indoor unit, and the rest of the system is in the outdoor unit. Between themselves, split systems differ in shape: there are floor, ceiling, wall air conditioners of this type.
3. Multi-split systems are distinguished by the fact that they have several internal blocks, and the external one is still one. Such air conditioners can also be floor, wall or ceiling.

Possible system malfunctions

Today, in order to install and successfully configure such a system at home or in the office, it is not necessary to know how the air conditioning compressor works. But it is necessary to understand some possible failures of air conditioning devices.

most common cause violations in split systems becomes water hammer. It occurs due to the fact that liquid freon enters the compressor. The agent does not have time to fully accept the gaseous state in the evaporator.

Water hammer occurs for several reasons.

Basically, this happens with cheap air conditioners that are not designed quite correctly. Therefore, at the slightest interruption in temperature, they can present unpleasant surprises. Water hammer can occur when starting the air conditioner in a room with negative temperatures. For an inexpensive system, a temperature of minus 10-12 degrees is enough to fail.

Dirty filters also cause water hammer. Air conditioners need to be taken care of. It is advisable to carry out regular preventive inspection of the system in order to avoid costly repairs.

Another malfunction of air conditioners is associated with a freon leak. This usually happens when incorrect installation tubes. Leaks sometimes occur in inexpensive, poorly designed systems. Among the very cheap models of air conditioners, you can find a factory defect, when the tubes are simply either poorly screwed on or initially leak. Freon leakage can be determined visually in a working system. It causes freezing on the back wall of the air conditioner.

If the air conditioner is installed incorrectly, air and moisture can enter the circuit. This will soon lead to a malfunction of the device. Air in the circuit often causes breakdowns in air conditioners.

Therefore, it is better to install a split system with the involvement of professionals who are not the first to install such units.

Benefits of an air conditioner

The conditioner creates optimal temperature conditions at home and office. AT recent times even appeared complex systems with the function of ionization and air humidification. It has a very beneficial effect on people, but on condition that the system is looked after. Because air conditioners, like any other devices, require cleaning and regular maintenance.

Dirty air conditioner filters are unlikely to make it work useful. There are cases when, due to neglected split systems, people had various ailments. If the owner of such a device wants to get the most out of it, then he must carefully monitor the condition of the air conditioner.

Air Conditioner Wiring Diagram - Regulatory Requirements

– The refrigerant pressure is above 3140 kPa (30.9 atmospheres) or below 196 kPa (1.93 atmospheres).

Why does the air conditioner turn on and off frequently?

I think in this case the reason, in principle, for the operation of the air conditioning system on Geely Emgrand. Freon entering the evaporator has low temperature and a liquid state, in the evaporator, freon is impaired and absorbs the heat of the surrounding air. When heat is absorbed, condensate is formed, which is discharged through a pipe under the hood or under the bottom of the car. So don't be scared when you see a puddle under your car.

To protect the evaporator from icing, it is equipped with a temperature sensor. At temperatures below +2 degrees, the compressor turns off and when the temperature rises to +4, it turns on again. It is this small temperature difference that causes the frequent switching on and off of the air conditioner.

But another reason may be a small amount of freon in the system lines.

You can indirectly check the amount of freon as follows:

Directly next to the refrigerant pressure sensor is a small viewing window. Through this window, you can evaluate the operation of the system, but only if the air conditioner is at least turned on.

At the moment the compressor clutch is turned on, foam or a large number of bubbles will be visible in this window. Some time after the start of the compressor, there should no longer be bubbles or there will be single rare bubbles. If bubbles or foam are constantly visible, then most likely there is not enough freon in the system. If the bubbles are not visible even when the clutch is turned on, then there is an excess amount of freon.

Electrical diagram of the air conditioner

When buying a room air conditioner, it is very important to choose the right technical characteristics and take a responsible attitude to the installation. According to statistics, most of the breakdowns of air conditioners occur due to their incorrect and unskilled installation. Correct sequence connecting the electrical circuit of the air conditioner is the key to its high-quality and long-term performance. If the air conditioner is still installed incorrectly, then the following negative characteristics may subsequently appear: condensate leakage into the room, freon leakage, etc.

There are two types of installation of air conditioners in the premises: standard and non-standard. The standard installation is the most common, installing the air conditioner near a window, since the compressor is located outside. It is possible to perform installation in rooms with completed repairs. Such installation is not expensive and does not take much time.

Non-standard installation of an air conditioner is quite expensive and painstaking work, which is recommended to be done only in the process of repairing a room, since it involves chasing the walls.

Regardless of which installation option you choose, in order to avoid all negative consequences, before starting the installation of the air conditioner and fixtures, it is worth finding out important points. For example, such as the external connection and wiring diagram, the electrical system of the device, the location of the input devices, the cross-section of the wires and the future cable routes, find out the characteristics of the walls involved in the wiring route. The electrical circuit of the air conditioner must comply with the rules for the installation of electrical installations and regulatory documents. The participation of a professional team of specialists with the necessary equipment is also important.
