What is Refrigerant in Car?
In a car’s air conditioning system, the refrigerant is a fluid that plays a crucial role in cooling down and dehumidifying the air. It absorbs the heat from the passenger compartment and releases it outside, resulting in a cooler and more comfortable environment inside the car.
Refrigerant in car systems usually undergoes a cycle of compression and expansion. When the refrigerant is compressed, it becomes a high-pressure gas and releases heat. This hot gas then flows to the condenser, where it cools down and condenses into a liquid. The liquid refrigerant passes through an expansion valve, which causes a pressure drop and allows the refrigerant to evaporate and absorb heat from the air inside the car.
The most commonly used refrigerants in car air conditioning systems are hydrofluorocarbons (HFCs) such as R-134a. These refrigerants are non-toxic, non-flammable, and have low ozone depletion potential. However, they are known to have high global warming potential, which has led to efforts to develop more environmentally friendly alternatives.
