摘要：The paper presents the thermodynamic analysis of an advanced heat pump and power plant which applies a modern heat engine of the gas turbine combined cycle for both heat and power production. This new technology ensures low cost of heat and a possibility to subsidise the sale of electricity. High efficiency of heat pump is conditioned by effective heat engine and high evaporating temperature of the heat pump working fluid in power plant condenser. The developed plant scheme provides for a possibility to regulate heat capacity during winter and summer regimes. The formula developed for the calculation of the powerfulness of the heat engine presents calculations for various heat capacities in any big city with a district heating and natural gas piping. The cold wave problem is proposed to be solved by adding a supplementary boiler instead of entering into the trans-critical cycle regime of the heat pump.
