Air conditioners in cars work by using a compressor to pressurize refrigerant gas, which is then cooled down by a condenser and passed through an expansion valve, which allows it to expand and cool even further. This cooled gas is then blown into the car's interior by a fan, providing cool air.
The presence of antifreeze in the radiator does not directly affect the operation of the air conditioner. Antifreeze is specifically used to regulate engine temperature and prevent it from freezing in cold weather. It does not circulate through the air conditioning system or interact with the refrigerant gas.
Therefore, while antifreeze is essential for the proper functioning of the car's engine, it is not necessary for the operation of the air conditioner. You can still use your car's air conditioner even without antifreeze in the radiator, as long as the air conditioning system is properly charged with refrigerant and in good working condition.
