How does Geely Borui air conditioner turn on warm air and how does Borui air conditioner turn on cold air?

Geely Borui air conditioner turns on the warm air and turns off the air conditioner switch. The hot water from the engine water tank reached the radiator in the heater and the blower came out. The hot air comes out after passing through the radiator to realize heating. The refrigeration of Geely Borui air conditioner is controlled by the AC switch on the air conditioner control panel. Turn on the air conditioner, turn on the AC switch, the electromagnetic clutch of the compressor is engaged, and the compressor starts to work. The refrigerant compressed by the compressor becomes high-temperature and high-pressure gas, radiates heat to the air in the condenser in front of the vehicle, condenses into high-pressure liquid, passes through the accumulator, filters and dries, reaches the expansion valve, throttles and depressurizes to become low-pressure liquid, and finally reaches the evaporator in the vehicle room to absorb heat by evaporation, thus realizing refrigeration.
