Description: The air-conditioning condenser is located between the car's grille and the engine-cooling radiator in which the gaseous refrigerant sheds heat and returns to a liquid state. The liquid refrigerant flows to the evaporator inside the dashboard, where it cools the cabin. The condenser works as a car radiator by dissipating out heat but also cooling the high-pressure refrigerant gas so it forms into a high-pressure liquid, then gets streamed to the receiver-dryer until it continues to the expansion valve.
