Problems solved by technology

[0004] However, during the use of the above-mentioned high-power inverter air conditioner, when the temperature of the power module is low and does not need to be cooled, the refrigerant will still exchange heat with the power module through the radiator, resulting in the loss of effective cooling capacity in the main flow of the refrigerant circulation

Abstract

The invention discloses an air conditioner and a control method thereof, and relates to the technical field of air conditioners. The flow rate of a refrigerant in a radiator is controlled, the effective loss of refrigeration capacity of a main refrigerant circulation flow path is reduced, and the energy efficiency of the air conditioner is improved. The air conditioner includes a compressor, a first heat exchanger, a second heat exchanger, the radiator and a power module. The compressor, the first heat exchanger and the second heat exchanger sequentially communicate through a refrigerant pipeto form a main refrigerant circulation loop, and the radiator communicates with the refrigerant pipe through a heat dissipation pipe to form a branch refrigerant circulation loop, and performs heat exchange with the power module. An electronic expansion valve is arranged in the heat dissipation pipe, and the controller can control the flow rate of the refrigerant in the refrigerant pipe flowing into the heat dissipation pipe through the electronic expansion valve. The air conditioner is used for adjusting air parameters.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a control method thereof. Background technique [0002] The air conditioner is a kind of heat exchange equipment, including the indoor unit of the air conditioner, which is installed indoors, and the heat or cold generated by the heating or cooling of the internal system of the air conditioner is sent to the room through the fan, so as to achieve the purpose of adjusting the indoor temperature. [0003] Among them, for high-power inverter air conditioners, the air-cooled heat dissipation mode is adopted, which cannot effectively remove the heat from the power module, thereby limiting the frequency of the compressor and affecting the performance of the air conditioner. At present, high-power inverter air conditioners usually use refrigerant cooling to cool the power module, that is, extract a part of refrigerant from the main flow of refrigerant cir...
