What is an Automotive Air Conditioning Circuit Diagram?

[BeckettLynn]

Automotive air conditioning refrigeration systems consist of components such as the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These parts are connected by copper pipes and high-pressure rubber hoses to form a sealed system. During operation, the refrigerant circulates through this closed system in different states. Below is an introduction to the working process of automotive air conditioning: 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. 2. Heat Dissipation Process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a significant 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 as a mist (fine droplets).
