Reasons for Golf's Air Conditioning Not Cooling
1 Answers
Reasons for Golf's air conditioning not cooling: 1. Insufficient or too little refrigerant. The main cause of insufficient refrigerant is usually minor leaks in the system. If there is not enough refrigerant in the air conditioning system, the amount of refrigerant sprayed into the evaporator from the expansion valve will inevitably decrease, leading to reduced heat absorption during evaporation in the evaporator, and consequently, reduced cooling capacity. 2. Too much refrigerant. The proportion of refrigerant in the air conditioning system has specific requirements. If the proportion is too high, it can affect heat dissipation, meaning more heat dissipation results in greater cooling capacity, and less heat dissipation results in lower cooling capacity. Similarly, adding too much cooling oil during maintenance can also reduce the heat dissipation of the refrigeration system. 3. Excessive impurities in the refrigerant and refrigeration oil, causing minor blockages and insufficient cooling capacity. If there are too many contaminants in the refrigerant and refrigeration oil throughout the air conditioning system, the filter screen of the filter will become clogged, reducing the flow capacity of the refrigerant, increasing resistance, and decreasing the amount of refrigerant flowing to the expansion valve, leading to insufficient cooling capacity. 4. Loose drive belt of the car's air conditioning compressor. A loose compressor drive belt can cause slippage during operation, reducing transmission efficiency, lowering the compressor's speed, and decreasing the delivery of compressed refrigerant, directly reducing the cooling capacity of the air conditioning system. 5. Moisture infiltration in the refrigeration system. There is a component in the refrigeration system called the dryer (or bottle), whose main task is to absorb moisture from the refrigerant to prevent excessive moisture in the refrigerant from reducing the cooling capacity.
