What is the function of an automotive air conditioning compressor?

The function of an automotive air conditioning compressor is to compress and transport refrigerant vapor. The automotive air conditioning compressor serves as the heart of the car's air conditioning refrigeration system, playing a crucial role in compressing and delivering refrigerant vapor. Compressors can be categorized into two types: fixed displacement and variable displacement. Based on their working principles, air conditioning compressors can be divided into fixed displacement compressors and variable displacement compressors. Safety precautions when handling refrigerants: 1. Do not handle refrigerants in enclosed spaces or near open flames; 2. Always wear protective goggles; 3. Avoid liquid refrigerant entering the eyes or splashing onto the skin; 4. Do not point the bottom of the refrigerant canister toward people, as some canisters have emergency venting devices at the bottom; 5. Do not place refrigerant canisters directly in hot water with temperatures exceeding 40 degrees Celsius.
I often ponder over the components of car air conditioning, and the role of the compressor is absolutely crucial. It's like the engine of the air conditioning system, compressing low-pressure refrigerant into high-pressure, high-temperature gas. This compressed refrigerant is then sent to the condenser to dissipate heat, turning into a liquid after releasing heat, and then flows into the evaporator to expand and absorb heat, cooling the air entering the car. The whole process cycles continuously, making the car interior cool. I also noticed that the compressor's operation relies entirely on the engine driving the belt to work. If the belt is loose or worn, the compressor's efficiency will be compromised. What's even cooler is that compressors come in different design types, such as fixed and variable displacement, with the latter being more fuel-efficient and energy-saving. In short, it's the core of the refrigeration cycle; without it, the air conditioning becomes useless, making summer driving unbearable.
