Car air conditioning systems promote a comfortable cabin interior and help prevent driver fatigue. During normal vehicle operation, a substantial amount of heat is created by the engine and exterior contributors like the road and sun. Your vehicle’s AC system is responsible for cooling, purifying, and circulating air. Your air conditioning system works through a series of processes that involve refrigerant. In your vehicle, the refrigerant is responsible for removing heat from the cabin compartment. Refrigerant goes through a continuous cycle of air compression that is dependent on your compressor’s drive belt. The compressor pumps the refrigerant through the system where it is transformed from a hot gas into a liquid and then cooled. Through a number of other components, such as the condenser, compressor, and evaporator, the liquid is again processed into a gas, pressurized, and vaporized before being released into the cabin as cool air.
