Why is the BMW 320 air conditioning not cooling?

[OGiselle]

BMW 320 air conditioning not cooling reasons are as follows: 1. Refrigerant issue: The reason why the car air conditioning is not cooling sometimes is due to problems with the refrigerant in the car air conditioning system. 2. Filter blockage: Sometimes, excessive impurities in the car air conditioning refrigerant and refrigeration oil can also cause the filter screen to become clogged, leading to reduced cooling effectiveness, increased resistance, and a decrease in the flow of refrigerant to the expansion valve, resulting in the car air conditioning not cooling. 3. Dryer saturation: There is a dryer in the car air conditioning refrigeration system, whose main task is to absorb moisture in the refrigerant and prevent excessive moisture in the refrigerant from causing a decrease in cooling capacity. When the desiccant in the dryer is saturated, moisture can no longer be filtered out. 4. Compressor drive belt too loose: Sometimes, the car air conditioning does not cool because the compressor drive belt is too loose, or it may be due to a decrease in the condenser's heat dissipation capacity, leading to a reduction in the air conditioning cooling capacity.
