How Your Car AC Keeps You Cool? Step-by-Step Explained

"The car AC system operates on the principles of thermodynamics and fluid mechanics. It consists of several key components working together to cool the air inside your vehicle. The basic function of your vehicle’s air conditioner is to cool and dehumidify the air inside the vehicle. Basically, your car's air conditioning is a heat exchanger moving the heat from the inside of your car to the outside.

And to do this, AC uses a substance called refrigerant. Refrigerants are special chemicals that can change from a gas to a liquid and back again, which is key to the whole process. The main parts of the air conditioning system are the compressor, condenser coil, receiver dryer, expansion valve, and evaporator coil.

In EVS the AC compressor is powered by an electric motor rather than a belt connected to the engine. This motor is driven by the vehicle's high voltage battery system.

Electric compressors have fewer moving parts and do not rely on belts which can reduce maintenance needs and improve reliability
In summary while both IC and Ev ac compressors achieve the same goal of cooling the vehicle's interior.

While the AC is essential for comfort, it does use power, and that can impact fuel efficiency. The engine's compressor, which runs the AC system, uses up energy, and on a hot day, it can reduce your car's fuel economy. This is one of the reasons electric vehicles (EVs) have a potential advantage—they don’t rely on the engine to run the AC system."
