Heating heat exchanger in motor vehicle coolant circuit has air to be heated in additional heating mode simultaneously heated by heat exchanger and gas cooler/condenser

摘要

The device (3) has a gas cooler/condenser (4) for refrigerant circuit additional heating mode, a functionally separate evaporator for cooling system mode, a coolant circuit containing the device and a refrigerant circuit with heat exchange surfaces. Gas cooler/condenser heat exchange surfaces for additional heating mode are integrated into the device. The air (5) to be heated in additional heating mode is simultaneously heated by the device and the gas cooler/condenser.
