Working principle of air conditioner
Principle of air conditioning refrigeration
After the air conditioner is electrified, the low-pressure steam of refrigerant in the refrigeration system is sucked by the compressor, compressed into high-pressure steam, and then discharged into the condenser. At the same time, the outdoor air sucked by the axial fan flows through the condenser, taking away the heat released by the refrigerant and condensing the high-pressure refrigerant vapor into high-pressure liquid. The high-pressure liquid is injected into the evaporator after passing through the filter and throttling mechanism, and evaporates at the corresponding low pressure to absorb the surrounding heat. At the same time, the cross-flow fan makes air continuously enter the fins of the evaporator for heat exchange, and sends the cooled air after heat release to the room. In this way, the indoor air continuously circulates and flows to achieve the purpose of cooling down.
Working principle of heating
Heat pump heating uses the compression condenser of refrigeration system to heat indoor air. When air-conditioning refrigeration, low-pressure refrigerant liquid evaporates and absorbs heat in the evaporator, and high-temperature and high-pressure refrigerant releases heat and condenses in the condenser. Heat pump heating is to switch the positions of suction and exhaust pipes of refrigeration system through electromagnetic commutation. The indoor coil of the original refrigeration evaporator becomes a condenser when heating, which makes the refrigeration system absorb heat outdoors and release heat indoors, thus achieving the purpose of heating.
