METHOD FOR OPERATING A HEAT PUMP ARRANGEMENT, AND HEAT PUMP ARRANGEMENT

摘要

The invention relates to a method for operating a heat pump arrangement (1), wherein a first fluid (26) flows through a first heat pump (2), a second fluid (27) flows through a second heat pump (3), and heat is transferred from the first fluid (26) to the second fluid (27) by means of a heat exchanger (19). A useful heat is drawn from the second fluid (27) at a fluid temperature (21) of at least 120 °C, and the useful heat of the second fluid (27) is dispensed at a volumetric heating power of the first fluid (26) and the second fluid (27) of at least 500 kJ/m3. The invention further relates to such a heat pump arrangement (1).
