Is it harmful to the car if the engine is running and the air conditioner is on without moving?
1 Answers
In general, idling the car with the air conditioner on does not cause significant damage to the vehicle. However, running the air conditioner while the car is stationary after starting the engine can slightly affect the engine, leading to carbon buildup. This can result in carbon deposits accumulating at the exhaust pipe's tailpipe opening and increased fuel consumption. It is advisable to minimize such situations. Below is relevant information: Definition: The car air conditioner is a crucial comfort feature in a vehicle, capable of both cooling and heating. When the air conditioner is in cooling mode, the compressor clutch engages, and the engine drives the compressor to operate. During operation, the compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, thereby cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the car's air vents to emit cold air. Precautions: The car air conditioner requires periodic refrigerant replenishment. If refrigerant is not added for an extended period, it can slow down the cooling speed and reduce the cooling efficiency. Most car air conditioners use R134a refrigerant.
