Heating method
Many cars will turn on the air conditioner even if the warm air is turned on, and the compressor will work. At this time, it is ok to manually close it. When heating, the compressor does not need to run. When heating, the automobile air conditioner uses the heat of the engine. When heating, the high-temperature coolant in the engine will flow through the warm air groove, and the wind from the blower will also pass through the warm air groove, so that the air outlet of the automobile air conditioner will blow out warm air.
The warm air box of automobile air conditioner is a heat exchanger, which allows the cooling liquid to heat the wind blown by the blower. The refrigeration principle of automobile air conditioner is also relatively simple. When cooling, the compressor clutch will be combined and the engine will drive the compressor to run. When the compressor is running, it can continuously compress the refrigerant and deliver it to the evaporation box.
