The invention relates to a method for minimising the energy consumption of a heat circulating machine (1), wherein the heat circulating machine (1) comprises a first heat exchanger designed as an evaporator (2) and a second heat exchanger designed as a liquefier (3, 30). In the operating state, a heating medium (4) is delivered from the evaporator (2) to a compressor (5), compressed by the compressor (5) to a condensing pressure, delivered to the liquefier (3, 30) and liquefied. The heating medium is then returned to the evaporator (2) via a depressurisation means (6) and is vaporised again, absorbing heat from a process fluid (7) to be cooled, wherein a turbomachine (8, 18) is provided in order to transfer heat from the heating medium (4) to the cooling fluid (9). According to the invention, the turbomachine (8, 18) and the compressor (5) are controlled in such a way that, depending upon a predetermined thermal effective output of the heat circulating machine (1), a sum of the power consumption by the turbomachine (8, 18) and the compressor (5) is minimised. Furthermore the invention relates to a heat circulating machine (1) for carrying out the method according to the present invention.
