Abstract: Heat exchange between an "intermediate substance" on the one side, and any "gas flow" and/or gases produced by hydrocarbon fuel combustion on the other, which is carried out directly in the "Completed multifunction element"  designed as a multifunction fan having additional elements and operational functions. Specific Features of such a heat exchange increase efficiency of heat exchange as at the expense of high speed of a "gas flow" organized as a vortex flow at a point of contact with heat exchanger coil and - additionally - because of temperature stratification of vortex onto hot and cold streams.   Sketch_1(A). The technological circuit of entering gas flow stratification into hot and cold streams: 1. Gas flow entering and vortex shaping; 2. Hot stream localization and heat exchange area;  3. Cold stream area; 4. Cold stream removing area.     Sketch_1(B). Basic concept of "Completed multifunction element":  1. Gas flow entrance; 5. Vortex shaper; 6. Heat exchanger coil; 4. Worked out gas removing stream.     The "completed multifunction element" consists of centrifugal fan body and/or one of internal parts of centrifugal fan working depending of selected mode either as a vaporizer or a condenser for "intermediate substance", and additionally it carries out temperature stratification of gas flow into hot and cold streams. Such stratification improves efficiency of heat exchange. Hydrocarbon-fuel burner is located in an air diffuser of the fan or combustion chamber is attached to the fan as an addition.     Sketch_1(C). Potential design of the "completed multifunction element" based on described above: 1. Input diffuser of gas flow;  12. Engine; 7. Fan-vortex shaper; 6. Heat Exchange coil of "intermediate substance";  9. Gas-flow stratification and heat exchange area;  8. Fan's body; 10. Hydrocarbon-fuel burner;  11. Diaphragm; 4. Exhausted gas flow.     "Heat pump" with the "Completed multifunction element" described above can work both as a classical heat pump in cooling or simple heating mode, and as heat recuperator carrying out heat exchange with environment and/or any gas flow including gases of hydrocarbon-fuel combustion in simple and in multifunctional mode. Such a design provides the ability to carry out hydrocarbon-fuel burning either directly into air diffuser of fan or an additional combustion chamber joined to diffuser.     Sketch_2(A). Potential heat pump design with the "completed multifunction element" and features described above: 1. Compressor; 2. The "completed multifunction element";  3. Reversing valve.     The present method and the heat pump based on it enables to carry out incineration of hydrocarbon-fuel outside of a consumer's premises, and to transmit heat to it by classical model of energy transmitting from heat pump to consumer's premises.     Sketch_2(B). Potential design of any premises artificial climate system with the heat pump described above.   A. The heat pump; 4. Indoor heat exchanger; 5. Air-returning inlet of air conditioning circulation's circuit; 6. Polluted or worked-out air-flow removing out off premises;  7. Fresh air exchange recuperating heat exchanger; 8. Connecting line set from heat pump to consumer's heat-exchanger;  9. Air-flow to hydrocarbon-fuel burner; 10. Artificial climate system air-distributor;  11. Hydrocarbon-fuel tank; 12. Hydrocarbon-fuel connecting line.     Using the heat pump described above enables to design artificial climate system most efficient for the purposes of energy-saving technology, to optimize heated floor space and to protect heated premises from impact hydrocarbon-fuel, flame and burning's products in case of hydrocarbon-fuel inflaming. Method of hydrocarbon-fuel usage described above and the heat pump carried out in accordance with this method increases efficiency of hydrocarbon-fuel usage, because temperature of exhausted gases may be reasonably lower than temperature of heated premises.
