What is the lowest temperature of a car air conditioner?
1 Answers
The lowest temperature inside a car air conditioner is around 10 degrees Celsius, and it also depends on the effectiveness of the car's refrigerant. Below is a related introduction to the air conditioning system: 1. Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas from the evaporator outlet and compresses it into a 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 refrigerant liquid with higher temperature and pressure passes through the expansion device, causing its volume to increase, and its pressure and temperature to 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 re-enters the compressor.
