APPARATUSES AND METHODS FOR USE OF A PUMP WITH A HEATABLE PUMP CHAMBER IN A HEAT-PUMP APPARATUS AND FOR OPERATING THE HEAT-PUMP APPARATUS

摘要

A heat-pump apparatus for heating purposes has a collector circuit for a heat source with a collector pump for a collector fluid, also has a refrigerant circuit with an evaporator and a condenser for a refrigerant in the refrigerant circuit and with a compressor and a pressure-relief valve, and additionally has a heating circuit with a heating pump for a heating fluid, with heating means for heating purposes. At least the collector pump and/or the heating pump are/is designed in the form of a pump with a heatable pump chamber for heating the fluid delivered by the pump.
