What are the reasons for a new car's air conditioning not cooling?
1 Answers
In general, the most likely reason for a new car's air conditioning not cooling is the lack of refrigerant in the vehicle. It could also be due to insufficient power supply voltage. Below is a detailed explanation of the reasons for a new car's air conditioning not cooling: 1. Insufficient refrigerant: Refrigerant, also known as coolant or freon, is the medium substance used in various thermal machines to complete energy conversion. It can absorb heat from the cooled object at low temperatures and then transfer it to cooling water or air at higher temperatures. A lack of refrigerant in the vehicle will cause the car's air conditioning not to cool. 2. Insufficient power supply voltage: The normal starting voltage for air conditioning is 220V ±10%. Almost all compressors can start at voltages above 200V. At voltages above 180V, 70-80% can start. At voltages above 160V, only a few machines can start. Insufficient power supply voltage will cause the car's air conditioning not to cool.
