The air conditioner is also known as the air conditioner host. Its function and value are self-evident, but few people know what the role of the air conditioner is. What is the structure of the air conditioner? The following decoration home decoration network Xiaobian will give you detailed answers, I hope to provide help for everyone.
What is the role of the air conditioner?
The high-pressure high-temperature gas discharged from the indoor unit is cooled outside by the fan (by the fan), and the condensed refrigerant liquid is sent to the evaporator of the indoor unit through the capillary to evaporate into a gas to absorb the heat in the room, so that the cycle is repeated. The temperature in the room will gradually decrease. Simply put, the refrigerant in the air conditioner plays a role in the circulation process - heat absorption in the room - heat dissipation in the outdoor - heat dissipation and then return to the indoor heat absorption.
Air conditioning outside machine structure Daquan:
1. Compressor: The heart called the air conditioner is a pump that circulates heat from the heat absorbing portion (evaporator) to the heat releasing portion (condenser). In order to prevent wear on the moving parts, the body must be filled with lubricating oil. A temperature relay is set at the head of the compressor, and the compressor automatically stops when the temperature is high.
2. Outdoor heat exchanger: A portion that exchanges heat with air according to the refrigerant circulating inside the piping. It is made of copper tube (U-tube) aluminum sheet.
3. Square valve: A valve that switches between cold and warm rooms.
4. Throttle decompression mechanism (capillary-expansion valve): The effect of decompression is achieved by refining the path. The capillary tube is a copper tube of 1.0 to 2.1 mm, and the expansion valve is opened and closed by a pulse motor valve for decompression.
5. Air filter: In order to adsorb foreign matter in the refrigerant lubricating oil, a metal mesh is provided in the refrigerant circuit. The filter is typically placed between the two-way valve and the pressure relief mechanism, as well as the reservoir of the compressor.
6. Silencer: A part that prevents the pulsation sound of the refrigerant emitted from the compressor discharge unit in order to expand the diameter of the refrigerant circuit. The silencer is usually mounted in a spit or connecting tube.
7. Dryer: The water inside the compression mechanism is frozen, and the refrigerant circuit will be blocked, so that the refrigerant circulation cannot be performed. When the compressor oil of the new refrigerant machine is decomposed by water, the performance of the lubricating oil will decrease.
8. Blowing out the wind (spiral fan-gathering ring): The propeller fan is used to improve the air supply efficiency of the outdoor unit. The direction in which the fan rotates is the same as the direction in which the screw is engaged.
9. Fan motor: AC motor and DC motor that function as indoor unit.
10. Isobutylene rubber sheet: The vibration of the piping is controlled to control the operation of the compressor, and the refrigerant sound emitted by the compression mechanism is blocked.
11. Sound absorbing material: to block the vibration sound and motor sound of the compressor. A fiber sheet made by sticking a resin sheet of a material such as polyethylene.
12. Water-blocking material: In order to prevent the intrusion of rainwater, it is attached to the sky board, electric goods box, terminal cover and so on. The air shower is made of waterproof, independent foamed sealing material.
13. Discharge pipe temperature sensor: Installed in the discharge pipe section of the compressor. When the compressor temperature changes, the number of revolutions of the compressor is controlled.
14. Outdoor heat exchange temperature sensor: installed in the copper tube part of the outdoor unit heat exchanger. When the heat exchange temperature changes, the action of the compressor is controlled.
15. External air temperature sensor: Installed in the aluminum part of the outdoor unit heat exchanger. In order to prevent the temperature of the control unit from rising due to the excessive outside air temperature, the electrical parts are damaged, and the number of revolutions of the compressor is controlled.
16, two, three-party valve: connected to the outdoor unit and piping parts. The valve part is made of rubber packing and the temperature is below 80 °C during welding.
The above is what Xiaobian brings to you. What is the role of the air conditioner?
