Is the AC in the car for cooling or heating?
1 Answers
The AC button in the car is the cooling switch. The AC button controls the air conditioning compressor. In summer, when using the air conditioning, you must turn on the AC button to activate the cold air. Below is an introduction to the air conditioning system: 1. Cooling system: The car air conditioning cooling is controlled by the AC switch on the air conditioning control panel. When the air conditioning is turned on, the AC switch is engaged, the compressor's electromagnetic clutch engages, and the compressor starts working. The compressor compresses the refrigerant, turning it into a high-temperature and high-pressure gas, which then dissipates heat to the air at the condenser in front of the car, condensing into a high-pressure liquid. After passing through the receiver and filter-drier, it reaches the expansion valve, where it is throttled and depressurized into a low-pressure liquid, finally reaching the evaporator inside the car. The refrigerant evaporates and absorbs heat in the evaporator, achieving cooling. 2. Heating system: The heating system simply utilizes the car's internal heat circulation and does not require the air conditioning compressor to be activated. Therefore, to turn on the heating, you only need to adjust the air conditioning temperature button without turning on the AC switch.
