ABSTRACT:
A heat pump for a vehicle includes a compressor helically wound with two pairs of concentric tubes forming the condenser and evaporator. One of the tubes of each pair is in fluid communication with glycol solution used as a heat transfer medium, and the other communicates the refrigerant. The first pair of concentric tubes operates as the condenser and produces condensed refrigerant to an expansion device. The evaporator comprises the second pair of concentric tubes and receives the expanded refrigerant for evaporating same. The glycol solution is communicated to air coupled heat exchangers to heat or cool the passenger compartment, depending on the vehicle mode.
