[ basic operation principle of air conditioner ]

The air conditioner performs a refrigeration cycle of the air conditioner by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

The low-temperature and low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas in a high-temperature and high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The air conditioner can adjust the temperature of the indoor space throughout the cycle.

The outdoor unit of the air conditioner refers to a portion of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the air conditioner includes an indoor heat exchanger, and an expansion valve may be provided in the indoor unit or the outdoor unit.

The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger serves as a condenser, the air conditioner performs a heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner performs a cooling mode.

The indoor heat exchanger and the outdoor heat exchanger are switched to be used as a condenser or an evaporator, a four-way valve is generally adopted, and specific reference is made to the arrangement of a conventional air conditioner, which is not described herein any more.

The refrigeration working principle of the air conditioner is as follows: the compressor works to enable the interior of the indoor heat exchanger (in the indoor unit, the evaporator at the moment) to be in an ultralow pressure state, liquid refrigerant in the indoor heat exchanger is rapidly evaporated to absorb heat, air blown out by the indoor fan is cooled by the coil pipe of the indoor heat exchanger to become cold air to be blown into a room, the evaporated and vaporized refrigerant is compressed by the compressor, is condensed into liquid in a high-pressure environment in the outdoor heat exchanger (in the outdoor unit, the condenser at the moment) to release heat, and the heat is dissipated into the atmosphere through the outdoor fan, so that the refrigeration effect is achieved by circulation.

The heating working principle of the air conditioner is as follows: the gaseous refrigerant is pressurized by the compressor to become high-temperature and high-pressure gas, and the high-temperature and high-pressure gas enters the indoor heat exchanger (the condenser at the moment), is condensed, liquefied and released heat to become liquid, and simultaneously heats indoor air, so that the aim of increasing the indoor temperature is fulfilled. The liquid refrigerant is decompressed by the throttling device, enters the outdoor heat exchanger (an evaporator at the moment), is evaporated, gasified and absorbs heat to form gas, absorbs heat of outdoor air (the outdoor air becomes cooler) to form gaseous refrigerant, and enters the compressor again to start the next cycle.
