An air conditioning system for a motor vehicle with heat pumps - and / or reheat - operating mode

摘要

An air conditioning system for a motor vehicle, which, for an air conditioning operation of the type and at least one further operating mode in the form of a heat pumps operation of the type and / or reheatbetriebsart is adapted to engage– a refrigerant circuit with a compressor (2), a refrigerant cooler (6) and a in an air supply duct (12) arranged, in the air conditioning operation type which functions as an evaporator inlet air / coolant - heat exchanger (4),– a coolant circuit for cooling a heat-generating vehicle component (1),– a the refrigerant circuit and the coolant circuit couples in a heat-transmitting manner refrigerant / coolant - heat exchanger (15) to which, in the coolant circuit of an internal combustion engine / coolant - heat exchanger (16) is connected upstream,– Means (19, 20) for the operation type dependent control of the refrigerant flow, whereby the latter in the air conditioning operation manner by the compressor via the refrigerant cooler to the feed air / coolant - heat exchanger is guided,– and a supply air delivery unit (13), the two operating modes with opposite supply air delivery directions,– the air conditioning system for carrying out a drying operation type is arranged, in which the supply air delivery device drying air for drying of the feed air / coolant - heat exchanger (4) in the direction perpendicular to the leading into the interior space of the supply air delivery direction opposite the air circulation direction via the feed air / coolant - heat exchanger (4), feeds, wherein the drying operation type of at least after switching off of the vehicle in a preceding klimatisierungs - or reheat is activated.
