The present invention pertains to combined power plant which comprises two independent systems—direct (Rankine) and reverse refrigerating cycles, which configured to produce electrical energy, heating and cooling, from waste or other heat sources, while both systems feed from the same heat sources with the temperature of 60° C. to 550° C. and more, with high coefficient of heat to electricity conversion effectiveness, up to 40% in direct cycle on behalf of placing evaporator of reverse cycle (i) into condenser (c) of direct cycle for receiving of preliminary programmed low temperature of condensation, for instance, minus 35° C. and according pressure, independently from temperature of ambient surroundings by means of use of pulse inflow method and appropriate control means, while the using up 80% and higher of waste heat, by usage of impact-foam vapor generators and condenser, while saving both cycles own energy by usage of pressure amplifiers (d, k) and instead of traditional hermetic compressor with electrical drive, usage of jet-flow compressor (f).
