  • Water Cooled Condenser in a Vehicle HVAC System
    Publication number: 20100307176
    Abstract: An HVAC system for use in a vehicle. The HVAC system comprises an evaporator, a refrigerant compressor that receives a refrigerant from the evaporator and compresses the refrigerant, a condenser that receives the refrigerant from the compressor and has fins with air flowing through the fins to remove heat from a refrigerant flowing through the condenser, and an expansion device that receives the refrigerant from the condenser and directs the refrigerant to the evaporator. The HVAC system also comprises a water tank that receives and stores water, a water spray pump that receives water from the water tank, and a nozzle that receives water from the water spray pump and is located adjacent to the condenser, with the nozzle selectively spraying water on the fins of the condenser.
