1、What are the usual components of a home air conditioner?
An air conditioner is mainly composed of an indoor unit, outdoor unit, adjacent to the (line), the controller (remote control).
2、How does the air conditioner achieve cooling?
The low-temperature liquid refrigerant evaporates into a gaseous state on the heat exchanger of the indoor unit and absorbs heat to cool the surrounding air, the gaseous refrigerant is compressed by the compressor into a high-temperature and high-pressure gas by the outdoor condenser to release heat into a liquid, and then the liquid refrigerant is saved and flows into the indoor unit to evaporate, thus reaching the purpose of refrigeration.
3、How does the air conditioner achieve heating?
The heating process of air conditioner is just the opposite of the cooling process. The high temperature and high pressure refrigerant is cooled in the indoor unit to release heat, which heats the air around the indoor unit, then the cooled refrigerant is saved and evaporated in the heat exchanger of the outdoor unit to absorb heat, and then compressed by the compressor into a high temperature and high pressure gas flowing into the indoor unit, so that the cycle reaches the purpose of heating.
4, how to achieve temperature control of air conditioning?
Refrigeration, when the temperature reaches the remote control set temperature, the compressor stops (or low frequency operation), when the temperature is higher than the remote control set temperature, the compressor restarts (or high frequency operation); heating, when the indoor temperature reaches the remote control set temperature, the compressor stops (or low frequency operation), when the temperature drops below the remote control set temperature, the compressor restarts (or high frequency operation) ).
5、What are the advantages of inverter air conditioners?
The main advantages of variable frequency air conditioners are:
①, the acceptance of low-frequency start, the start current is small nuisance to the grid, saving energy;
②, can quickly cooling, heating;
③, after the start of durable operation temperature control accuracy can reach ± 0.5 ℃.
6、Inverter type air conditioner why will save some electricity?
Inverter-type air conditioners accept the inverter compressor, inverter air conditioners can be based on the room cooling (heat) load shift automatically adjust the operating frequency of the compressor. When the load hour running frequency is low, when the compressor consumes less power, while preventing the frequent opening and closing, thus doubling the power saving.
7, what is the role of the compressor in the air conditioner?
In the operation of the air conditioner, the compressor low temperature, low pressure refrigerant compressed into high temperature, high pressure refrigerant, to promote the refrigerant in the refrigeration cycle system has been the cycle of flow, to reach the purpose of cooling (heating).
8、How does the refrigerant change from liquid state to gas state in the air conditioner?
The high temperature and high pressure gas refrigerant from the compressor is cooled by the heat exchanger and becomes a high pressure liquid. After the liquid refrigerant flows through the capillary tube or electromagnetic expansion valve, the pressure is greatly reduced, causing the refrigerant to evaporate (absorb heat) into a gaseous state.
9、What is the role of the circuit board in the air conditioner?
The circuit board of air conditioner is the control center of air conditioner, which is used to collect signals from remote control or sensors, etc., and issue instructions to compressor, fan motor and other parts after processing, so that they can operate in an appropriate way.
