Abstract
The invention is based on a climate control system for a vehicle that is driven by an internal combustion engine (), having a heating heat exchanger () which is connected to a coolant loop () of the engine () and is preceded upstream of a blower () by an evaporator (), and a compressor () in a refrigerant loop (), during a cooling mode, pumps a refrigerant via a gas cooler () and via an expansion valve () to the evaporator () and during a heating mode pumps it to the evaporator bypassing the gas cooler (), and between the coolant loop () and the refrigerant loop () a coupling heat exchanger () is provided. It is proposed that the coupling heat exchanger () is disposed upstream of the gas cooler () on the side of the refrigerant loop () on the compression side of the compressor (); that a bypass line () is connected parallel to the gas cooler (), and the flow through the gas cooler () and the bypass line () is controlled as a function of operating parameters via a switching valve () in the bypass line () and one switching valve () each at the inlet and outlet, respectively, of the gas cooler (); and that in the heating mode, the evaporator () serves as a heat source.
