In the context of a method for generating steam and cold by supplying electrical energy to a compression refrigeration machine (2) and a high-temperature heat pump (3), it is intended to provide a solution by which it is possible to simultaneously provide steam and cold for application in industrial processes. This is achieved by, in at least one heat exchanger (6) arranged in the refrigerant circuit (4) in the compression refrigeration machine (2), cold being extracted from an inflowing refrigerant (11), preferably at a temperature of < 0°C, this cold being supplied to refrigerant circulating in the refrigerant circuit (4) and entering the at least one heat exchanger (6), the refrigerant in the refrigerant circuit (4) is then compressed and thus heated, and is fed, heated in this manner, in the refrigerant circuit (4) to the heat exchanger apparatus (8), where heat energy is extracted from the inflowing refrigerant and is supplied to the heat-transfer fluid circulating in the heat-transfer fluid circuit (13) of the high-temperature heat pump (3) so as to heat the heat-transfer fluid, this heated heat-transfer fluid then being heated in the heat-transfer fluid circuit (13) by compression such that the heat energy content of the compressed heat-transfer fluid is sufficient to then, in at least one further heat exchanger (17) arranged in the heat-transfer fluid circuit (13), using heat energy extracted from heat-transfer fluid fed to this further heat exchanger (17) and supplied to water (25), in particular feedwater, flowing through this at least one further heat exchanger (17), boil the water (25), in particular feedwater.
