During refrigeration, the compressor clutch will be engaged, and the engine will drive the compressor to run at this time.
When the compressor is running, it can continuously compress the refrigerant and deliver it to the evaporation box.
The refrigerant continuously expands and absorbs heat in the evaporation box, so that the refrigerant cools the evaporation box.
The cooling evaporation box can cool the wind from the blower, so that the air outlet of the automobile air conditioner can blow out cold air.
The refrigerant used in automobile air conditioning is r 134a, which needs to be added regularly. If refrigerant is not added for a long time, it will affect the refrigeration effect of automobile air conditioner and slow down the refrigeration speed.
