What happens if you turn off the engine without turning off the air conditioner first?
1 Answers
Turning off the engine without turning off the air conditioner first will not cause any damage to the vehicle. Here is the relevant information: 1. Composition of the car air conditioning system: The car air conditioning system is basically composed of an air conditioning compressor, high-pressure pipes (some high-pressure pipes are equipped with a liquid-gas separator), a condenser, a dryer, a high-pressure sensor, an expansion valve, an evaporator, low-pressure pipes, compressor oil, and refrigerant. 2. Working principle: When the ignition switch is turned off, the engine will stop quickly, and the compressor will also stop working at the same time. The pressure difference of the refrigerant in the high and low pressure pipes will gradually equalize, and the entire air conditioning system will enter a balanced and static state. Therefore, there is absolutely no impact on the air conditioning system itself.
