Why is the car's air conditioning not cooling properly?
1 Answers
There are 4 main reasons why a car's air conditioning may not cool properly: 1. The issue might be with the refrigerant in the car's air conditioning system. 2. Sometimes, excessive impurities in the refrigerant or frozen oil can clog the filter screen, increasing cooling resistance and reducing the flow of refrigerant to the expansion valve, leading to poor cooling. 3. The desiccant in the dryer may become saturated, preventing further moisture filtration. The car's air conditioning system has a dryer whose main function is to absorb moisture from the refrigerant and prevent excessive moisture from reducing cooling efficiency. When the desiccant is saturated, it can no longer filter out moisture. 4. The compressor's drive belt may be too loose, or the condenser's heat dissipation capacity may have decreased, both of which can reduce the air conditioning's cooling performance. Here are some air conditioning maintenance tips: 1. Avoid using the air conditioning's internal circulation mode for extended periods; 2. Do not frequently adjust the direction of the air conditioning vents.
