What Components Make Up an Automotive Refrigeration System?
1 Answers
The automotive air conditioning refrigeration system consists of components such as the compressor, condenser, receiver-drier, expansion valve, evaporator, and blower. These parts are connected into a sealed system using copper pipes (or aluminum pipes) and high-pressure rubber hoses. During operation, the refrigerant circulates through this closed system in different states. Below is relevant information: The refrigerant circulates through this sealed system in varying states, with each cycle comprising four fundamental processes: 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 before discharging it. 2. Heat Dissipation Process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where, due to the drop in pressure and temperature, it condenses into a liquid and releases a significant amount of heat. 3. Throttling Process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, causing its volume to increase while its pressure and temperature drop sharply, exiting the expansion device as a mist (fine droplets). 4. Heat Absorption Process: The mist-like refrigerant liquid enters the evaporator, where, because the refrigerant's boiling point is much lower than the temperature inside the evaporator, it evaporates into a gas. During the evaporation process, it absorbs a substantial amount of heat from the surroundings, after which the low-temperature, low-pressure refrigerant vapor re-enters the compressor.
