What is the normal temperature range for a car air conditioning condenser?

[McAnna]

Car air conditioning condenser temperatures are divided into three sections: 1. Temperature at the condenser inlet: typically between 70~90°C. 2. Temperature at the middle section of the condenser: usually around 50°C. 3. Temperature at the condenser outlet: generally between 42~50°C. The air conditioning system operates through four cyclical processes to lower the temperature of air around the evaporator. Below is a detailed explanation of these four 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 it condenses into liquid due to reduced pressure and temperature, releasing significant heat. (3) Throttling process: The higher-temperature and higher-pressure refrigerant liquid expands through the expansion device, causing its volume to increase while pressure and temperature drop sharply, exiting as a mist (fine droplets). (4) Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the refrigerant's boiling point is much lower than the evaporator's internal temperature, it evaporates into gas, absorbing substantial surrounding heat during this process. The resulting low-temperature, low-pressure refrigerant vapor then re-enters the compressor.
