Abstract
A vehicle having a heating and cooling system includes a refrigerant loop having first and second heat exchangers, a compressor, and an expansion device, and a coolant loop. The coolant loop is connected, in one embodiment, to allow a first flow of coolant to be directed through each of a plurality of heat exchangers and an auxiliary coolant loop and to allow a second flow of coolant to be directed through each of the plurality of heat exchangers and the auxiliary coolant loop dependent upon a mode of operation. A control module controls the first and second flows dependent upon the mode of operation. In one other embodiment, the coolant loop includes manifolds and reservoirs with regulating sending and receiving ports for directing the flows. The auxiliary coolant loop is for heating/cooling one or more components, such as a battery, dependent upon the mode of operation.
