Abstract
A vehicle climate control system having a separate control for first and second separate areas of the vehicle. The climate control system includes a three-fluid heat exchanger having a first path with a first inlet and first outlet, and a second path with a second inlet and second outlet. The first path communicates refrigerant between the first inlet and first outlet and the second path communicates coolant between the second inlet and second outlet without the refrigerant and the coolant being mixed. A primary refrigerant loop is interconnected by a refrigerant line with the refrigerant line being connected to the inlet and outlet of the first path. A secondary loop is connected to the inlet and the outlet of the second path such that the coolant flows through the three-fluid heat exchanger to selectively cool or heat the second area of the vehicle by heat transfer within the three-fluid heat exchanger. A heating loop is selectively connected to the secondary loop, three-fluid heat exchanger and the vehicle engine coolant supply for supplying heat to the first and second areas of the vehicle.
