What are the reasons for the BYD Song Pro air conditioner not cooling?
1 Answers
The reasons for the BYD Song Pro air conditioner not cooling could be insufficient or too little refrigerant, excessive refrigerant, loose drive belt of the car air conditioner compressor, use of unqualified refrigerant and refrigeration oil, or moisture infiltration into the refrigeration system, among others. Causes and solutions for the air conditioner not cooling: 1. Insufficient or too little refrigerant: A common reason for the car air conditioner not cooling is insufficient or too little refrigerant, which is likely caused by minor refrigerant leakage. Solution: If obvious bubble flipping is observed, it indicates a severe shortage of refrigerant. If the refrigerant is insufficient or too little, the solution is to add refrigerant. 2. Excessive refrigerant: Too much refrigerant can also cause the air conditioner not to cool. There is a required proportion of refrigerant volume in the air conditioning system. If the proportion is too high, it will affect heat dissipation. Similarly, adding too much cooling oil during maintenance will also reduce the heat dissipation of the refrigeration system. Solution: If it is confirmed that there is too much refrigerant, some can be slowly released from the low-pressure side maintenance port of the air conditioning system. 3. Loose drive belt of the car air conditioner compressor: Car refrigeration relies on refrigerant, and refrigerant transmission depends on the air conditioner compressor, with the drive belt being an important moving part that drives the compressor. If tightening is ineffective or the drive belt has cracks, aging, or other damage, a new drive belt should be replaced. 4. Unqualified refrigerant and refrigeration oil: Excessive impurities in the refrigerant and refrigeration oil can also clog the car air conditioner's filter, leading to the air conditioner not cooling. The increased resistance reduces the flow of refrigerant to the expansion valve, resulting in insufficient cooling. In this case, qualified refrigerant must be selected for maintenance, as it plays a crucial role in the car air conditioner. 5. Moisture infiltration into the refrigeration system: If moisture infiltration into the car air conditioner refrigeration system causes insufficient cooling or no cooling, the desiccant or drying tank in the car air conditioner should be replaced. At the same time, the system should be evacuated again, and a new, appropriate amount of refrigerant should be injected.
