How Does an Automotive Air Conditioning Refrigeration System Work?

[LaJames]

Here is how an automotive air conditioning system works: The automotive air conditioning refrigeration system consists of a compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These components are connected by copper pipes and high-pressure rubber hoses to form a sealed system. When the refrigeration system operates, the refrigerant circulates in different states within this sealed system. Additional information: Below is the working process of an automotive air conditioning system: 1. Compression process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. 2. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser. Due to the reduction in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a significant amount of heat. 3. Throttling process: The high-temperature, high-pressure refrigerant liquid passes through the expansion device, causing its volume to expand, and its pressure and temperature drop sharply, exiting the expansion device in a mist form (fine 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 gas. During the evaporation process, it absorbs a large amount of heat from the surroundings, and the low-temperature, low-pressure refrigerant vapor then re-enters the compressor.
