FIELD: energy.SUBSTANCE: heat pump unit that is operated on low-temperature working medium - carbon dioxide on the cycle for Lorentz, comprising a compressor, a drive electric or gas turbine engine, heat exchangers to produce heat-carrying medium, an evaporator of the working medium and the low-grade heat source, at that the compressor performs multistage compression of the working element, which after each compression stage is partially removed from the compressor and by means of heat exchangers is used for independent heating heat-carrying mediums, and the working medium flows cooled in the heat exchangers, having different pressures, are incorporated into a joint flow entering the evaporator of the heat pump unit, which is provided by the pressure equalisation through the throttle valves.EFFECT: invention enables to perform the environmentally friendly production technology of heat in industry.6 cl, 3 dwg |
