The most complex air conditioning unit scheme for wall split systems. Therefore, they can be taken as an example.
Outdoor unit
The outdoor unit circuit of the air conditioner consists of the following components:
- Four way valve;
- Main board;
- Fan;
- Capacitor;
- Compressor;
- Cold circuit filter;
- Fitting fitting;
- Box.
The compressor increases the density of the refrigerant and starts it to move along the cold circuit. Scroll and reciprocating compressors are distinguished. The latter cost less, but they often break in frost. The layout of the air conditioning compressor varies depending on the type of compressor.
The four-way valve is a mandatory part of devices operating in two modes. When heated, it directs the refrigerant to another circuit. In this case, the outer part begins to produce cold, and the inner heat.
The block diagram of the heat-cold air conditioner also contains the main board. In models operating in one mode, the boards are mounted only in the room part, which is in more acceptable temperature conditions.
The circuit of the outdoor unit of the air conditioner necessarily contains a fan for air movement around the condenser.
The condenser reduces the temperature of the refrigerant and precipitates it.
The refrigerant system filter protects the inside of the compressor from clogging.
Mounting fittings are located at the mounting points of the copper tubes.
The box covers the entrances of the tubes and the place of attachment of the wires.
Indoor unit
The air conditioner control unit circuit includes the following components:
- Cap;
- Large filter;
- Radiator;
- Blinds are horizontal;
- Scoreboard;
- Fine filter;
- Fan;
- Blinds are vertical;
- Capacity for collecting condensate;
- Main board;
- Fitting fitting.
Each circuit of the air conditioning unit certainly includes a cover in the form of a lattice that passes air into the device.
A large filter is a plastic grille over which a nonwoven fabric is stretched. It is necessary to delay hair, dust lumps. Needs washing once every 2 weeks.
Radiator - the temperature of the refrigerant increases in it, as a result of which it evaporates.
Vertical and horizontal blinds are necessary to give the air flow the desired direction.
The panel displays the basic data required by the user.
Small filter - can be filled with various substances and have different effects (remove static electricity, remove odors). In simple models, it may not be at all.
The circuit of the air conditioning control unit may not contain a condensate collection tank, but in the device it is required and is located under the radiator, condensation drips into it, then it flows out of the apartment along the pipe.
The main control board for the entire air conditioner is located precisely in the indoor unit, it is in it that the circuit of the air conditioning control unit is located.
From below, copper tubes leading to the outdoor unit are connected to the mounts.
