What are the hazards of starting the car with the air conditioner on?
1 Answers
Starting the car with the air conditioner on has a slight impact on the engine, making it prone to carbon buildup, which can lead to carbon deposits accumulating at the exhaust pipe's tailpipe, and it also increases fuel consumption. Although idling the car with the air conditioner on does not cause significant harm, it is still recommended to minimize such situations. Here is some additional information: 1. Principle of car air conditioning cooling: The car air conditioner is a crucial comfort feature in a vehicle, capable of both cooling and heating. When cooling, the compressor clutch engages, and the engine drives the compressor to operate. 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 air conditioner to blow cold air from the vents. 2. Principle of car air conditioning heating: The heating principle of the car air conditioner is simpler. During heating, the high-temperature coolant from the engine enters the heater core, and the air blown by the blower passes through the heater core, allowing the car air conditioner to blow warm air from the vents.
