Heat pump device, use of a pump with heatable pump chamber in a heat pump device and method for operating a heat pump device

摘要

The device (11) has a collector circuit (13) that comprises a collector pump (20) which is adapted to collect a collector fluid. The collector circuit is adapted to interact with an evaporator (22) to dissipate heat to a refrigerant (23) in a refrigerant circuit. A condenser (26) is adapted to interact with a heating circuit (30) to dissipate heat from the refrigerant. The collector pump or a heating pump (35) is provided with a heatable pump chamber for heating a heating fluid (32) delivered by the pump. An independent claim is included for a method of operating a heat pump device.
