What is the working process of an automotive air conditioning system?
1 Answers
Automotive air conditioning system working process is: 1. Compression process: The compressor sucks in low-temperature and low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature and high-pressure gas, which is then discharged from the compressor. 2. Heat dissipation process: The high-temperature and high-pressure superheated refrigerant gas enters the condenser. Due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid and releases a large amount of heat. 3. Throttling process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, where its volume increases, and its pressure and temperature drop sharply, exiting the expansion device in a mist form. 4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During the evaporation process, it absorbs a significant amount of surrounding heat, and then the low-temperature and low-pressure refrigerant vapor re-enters the compressor. This working principle cycle repeats continuously, thereby reducing the temperature of the air around the evaporator.
