One heat pump circuit (16-18) transmits its energy to water which, in a following heat pump circuit (30,32,34) is evaporated and compressed in two or more stages. The steam is then fed via a conduit (2) to the process requiring heat (1). The condensate water (3) received from the heat-requiring process is expanded in two or more stages, and the expanded steam obtained from the condensate water is fed via a conduit (36) to the steam compressed in several stages. It is then fed between two of the stages (32,34) of the first heat pump circuit. |
