DEVICE AND METHOD FOR DEICING A HEAT EXCHANGER IN EVAPORATOR OPERATION OF A COOLING SYSTEM AND VEHICLE HAVING SUCH A DEVICE

摘要

In order to deice a heat exchanger in evaporator operation of a cooling system (1), which heat exchanger was iced at low evaporation temperatures, wherein refrigerant (30) can flow or flows through the heat exchanger in evaporator operation (20), a device for deicing such a heat exchanger in evaporator operation (20) is a heat exchanger device (12, 55) which is situated in a second coolant circuit or a separate, connectable and disconnectable path of the at least one first coolant circuit (65) and can be provided or is provided in heat exchange with the heat exchanger in evaporator operation (20). In a vehicle (100), in particular a land vehicle, having at least one electric drive (50) and/or at least one traction battery (59) and having at least one cooling system (1) which can be or is operated in heat pump mode and which has at least one heat exchanger in evaporator operation (20) which, as part of a refrigerant circuit (66), can have or has refrigerant (30) flowing through it, and having at least one first coolant circuit (65), at least one heat exchanger device (12, 55), which is provided in a second coolant circuit or a separate, connectable and disconnectable path of the at least one first coolant circuit (65), is placed in heat-conducting contact with the heat exchanger in evaporator operation (20) for deicing the heat exchanger in evaporator operation.
