What Causes the Abnormal Noise When the Sylphy's Air Conditioner is Turned On?
1 Answers
Possible causes include slippage of the air conditioning compressor clutch or a malfunctioning blower. Below are the four cyclic processes of a car's air conditioning system: 1. Compression Process: The compressor inhales 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, where, due to the decrease in pressure and temperature, the refrigerant gas condenses into a liquid, releasing a significant amount of heat. 3. Throttling Process: The higher-temperature and higher-pressure refrigerant liquid passes through the expansion device, increasing in volume while experiencing a sharp drop in pressure and temperature, exiting the expansion device as a mist (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 a gas. During the evaporation process, it absorbs a large amount of surrounding heat, after which the low-temperature, low-pressure refrigerant vapor re-enters the compressor. These processes repeat continuously to achieve the effect of lowering the temperature of the air around the evaporator.
