FIELD: combined systems for heating and cooling.
SUBSTANCE: invention relates to a hybrid device, which includes a fuel element and a thermoacoustic refrigerator, which produces thermoacoustic energy using exhaust gas leaving the power unit. Hybrid system according to the present invention includes a device on fuel elements and thermoacoustic refrigerator (14), which comprises generating thermoacoustic energy section (20), wherein thermoacoustic energy is performed by a temperature gradient between a high-temperature and a low-temperature sides; and cooling section (21), wherein the cooling function is performed on the low-temperature side using a temperature gradient between the high-temperature and the low-temperature sides; a heat exchanger of the hybrid system, which performs heat exchange between exhaust gas leaving the device on fuel elements and a fluid medium and reduces the temperature of the exhaust gas after its passing through the high-temperature side of the thermoacoustic section; herewith the thermoacoustic refrigerator is installed on a circulating flow between heat exchanger (6) and the high-temperature side of the cooling section and is intended for cooling the fluid medium of the circulation flow, which passes through the outlet of heat exchanger (6).
EFFECT: higher total efficiency of generating energy devices of the hybrid system is technical result of the invention.
