Abstract

The invention provides a cooling device for cooling refrigerant of a vehicle air conditioner. The cooling device comprises a water storing device, a heat exchanging tube and a pump. The water storing device is used for collecting condensate of the vehicle air conditioner; the heat exchanging tube is sleeved on the exterior of an inlet tube of an expansion valve of the vehicle air conditioner to form a flowing channel of condensate; and the pump is used for pumping the condensate in the water storing device into the heat exchanging tube. The invention further provides a cooling method for cooling the refrigerant of the vehicle air conditioner. The cooling method includes firstly collecting the condensate of the air conditioner into the water storing device, and secondly cooling the condensate in the inlet tube of the expansion valve of the vehicle air conditioner by utilizing the condensate. According to the cooling device, the condensate produced during the operation of the vehicle air conditioner is collected and serves as cooling medium for the inlet tube of the expansion valve of the air conditioner. Thus, the heat exchanging efficiency of the air conditioner is improved.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a cooling device and a cooling method for cooling a refrigerant of a vehicle air conditioner. Background technique [0002] When the vehicle's air conditioner is running in a refrigeration cycle, the air flowing through the surface of the evaporator of the air conditioner will condense into condensed water when it is cold. Also, the higher the air humidity, the more condensed water will be produced. Under normal circumstances, the condensed water is directly discharged out of the car through the drain pipe. [0003] attached figure 1 Shown in is the pressure-enthalpy diagram of the refrigeration cycle of the air conditioner, where the abscissa shows the temperature change trend of the refrigerant, and the ordinate shows the pressure change trend of the refrigerant. In the figure, ①→② indicates the process of the compressor compressing the refrigerant; ②→③ indicates the heat exc...
