What is the working principle of an automotive air conditioning system?

[LucyAnn]

The working principle of an automotive air conditioning system involves connecting various components through copper pipes and high-pressure rubber hoses to form a sealed system. During operation, the refrigerant circulates within this closed system in different states, with each cycle consisting of four fundamental processes: compression, heat dissipation, throttling, and heat absorption. Automotive air conditioning refers to the air conditioning unit installed in vehicles, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and enhancing driving safety. Typically, automotive air conditioning systems include cooling devices, heating devices, and ventilation devices. This integrated system efficiently utilizes the limited space inside the vehicle, featuring a simple structure and ease of operation.
