What is the general cooling capacity of a car air conditioner?
1 Answers
The cooling capacity of a car air conditioner is generally 5KW. Below is a detailed introduction to the working process of a car air conditioner: 1. Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas, and then discharges it 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 refrigerant liquid with higher temperature and pressure passes through the expansion device, causing its volume to increase, and the pressure and temperature drop sharply, discharging from the expansion device in a mist form (tiny liquid droplets). 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 large amount of surrounding heat, and then the low-temperature and low-pressure refrigerant vapor enters the compressor again.
