Can You Turn on the Air Conditioning When the Car is Parked?

[DelCarter]

It is best not to turn on the air conditioning when the car is stationary. This is because the air conditioning consumes fuel during operation, and prolonged use in this state can adversely affect the car's engine, leading to carbon buildup in the generator and even clogging the exhaust pipe's tailpipe. Additionally, running the air conditioning while stationary increases fuel consumption. Below is more information about car air conditioning: 1. Cooling Principle: When the car air conditioning is cooling, the compressor clutch engages, causing the engine to drive the compressor. The compressor continuously compresses the refrigerant and delivers it to the evaporator. The refrigerant expands inside the evaporator, absorbing heat, which cools the evaporator. The cooled evaporator then cools the air blown by the blower. 2. Heating Principle: When the car air conditioning is heating, the engine's high-temperature coolant flows through the heater core. At the same time, the air blown by the blower also passes through the heater core, allowing the air conditioning vents to blow warm air.
