Device and method for deicing a heat exchanger in the evaporator operation of a refrigeration system and vehicle with such a device

摘要

In order to enable defrosting of a heat exchanger which is frozen at low evaporation temperatures in the evaporator operation of a refrigeration system (1), wherein the heat exchanger in the evaporator operation (20) can be flowed through or through with refrigerant (30), a device for defrosting such a heat exchanger in the evaporator operation (20) is provided. a heat exchanger device (12, 55) which is providable or provided in heat exchange with the heat exchanger in the evaporator operation (20). In a vehicle, in particular a land vehicle, with at least one electric drive (50) and / or at least one traction battery (59) and with at least one refrigeration system (1) having at least one heat exchanger in the evaporator operation (20), at least one heat exchanger device is necessary for defrosting the heat exchanger in evaporator operation (12, 55) provided in heat-conducting contact with the heat exchanger in the evaporator operation (20).
