Must the Car Air Conditioning Be Turned On with the Engine Running?
1 Answers
Electric vehicles can turn on the air conditioning without starting the car, but conventional fuel-powered vehicles cannot. This is because the air conditioning in conventional fuel-powered cars is driven by the engine, so the air conditioning cannot be used if the car is not started. Additionally, turning on the air conditioning with only the power on but without starting the engine will not produce any cooling or heating effects. Below are some precautions for using car air conditioning: 1. Regularly add refrigerant: The refrigerant used in car air conditioning is R134a, and it needs to be replenished periodically. If refrigerant is not added for a long time, the cooling effect of the car air conditioning will deteriorate, and the cooling speed will slow down. 2. Regularly clean the car air conditioning: The air conditioning system can harbor many bacteria. When cleaning the air conditioning and adding refrigerant, it is essential to go to a professional institution and have experts use professional equipment to perform the operation.
