What Causes Car Air Conditioning Not to Cool During Midday High Temperatures?
1 Answers
Car air conditioning not cooling during midday high temperatures may be due to reasons such as insufficient refrigerant, poor heat dissipation, or compressor failure. Detailed explanations are as follows: 1. Insufficient Refrigerant: This is a normal condition, not a malfunction. The air conditioning will not completely fail to cool but will have reduced efficiency. However, this situation should be relatively rare. Since refrigerant is not a consumable, unless the vehicle has been involved in a severe rear-end collision or had its air conditioning pipes or other components disassembled, affecting the sealing, the refrigerant generally does not deplete on its own. 2. Poor Heat Dissipation: The radiator and condenser are crucial heat dissipation components of the vehicle. If they are too dirty, it can lead to poor heat dissipation, which not only causes the engine to overheat but also directly affects the cooling efficiency of the air conditioning. Therefore, if the air conditioning performance is unsatisfactory during hot weather, the first consideration should be whether the vehicle's cooling system has been cleaned. 3. Compressor Failure: If the compressor malfunctions, the air conditioning will not operate. Damage or malfunction of the compressor capacitor can cause the compressor to stop working. Symptoms include both the indoor and outdoor units running, but the compressor not functioning, resulting in no cooling effect and the compressor becoming very hot.
