Abstract
In a combustion engine driven refrigerant vapor compression heat pump system, an integrated heat exchanger is provided which recovers and uses waste heat from the combustion engine coolant and exhaust stream, further produces auxiliary heat when the heat pump system is operating in the heating mode of operation, and uses some of the same components to cool the combustion engine coolant when the heat pump system is operating in the cooling mode of operation. Additional features are integrated into the heat exchanger to provide engine oil cooling and heating.
