Abstract
A heat exchanger module includes a glycol coolant circuit adapted to function as a heat pump for the heating of the interior passenger compartment of the motor vehicle with a glycol/water mixture as the heat carrier, a refrigerant circuit, and a glycol/refrigerant heat exchanger positioned between and interconnecting the cooling circuit and the refrigerant circuit, wherein the glycol/refrigerant heat exchanger has integrated connection lines for heat transfer from the coolant circuit to the refrigerant circuit.
