Do You Need to Start the Engine to Turn on the Air Conditioner?

[DiDante]

To turn on the air conditioner, you must start the engine. Without starting the engine, you cannot use the air conditioner, whether for heating or cooling. Introduction to Vehicle Air Conditioning: Vehicle air conditioning consists of a compressor, condenser, throttle element, evaporator, fan, and necessary control components. It is an air conditioning system designed to regulate the temperature and humidity inside the vehicle, providing a comfortable environment for the driver. Working Principle of Vehicle Air Conditioning: When the compressor is operating, it sucks in low-temperature, low-pressure gaseous refrigerant from the evaporator. After compression, the temperature and pressure of the refrigerant increase, and it is sent to the condenser. Inside the condenser, the high-temperature, high-pressure gaseous refrigerant transfers heat to the outside air passing through the condenser and liquefies, turning into a liquid.
