METHOD OF COMBINED PRODUCTION OF COLD AND HEAT FOR ROOMS CONDITIONING AND PLANT FOR ITS REALIZATION Russian patent published in 1996 - IPC

FIELD: air-conditioning systems for rooms. SUBSTANCE: when plant operates for production of cold, main flow of air after expansion in turbine is directed for heating in course of regenerative heat exchange with circulating flow of air of room being conditioned. When plant operates for production of heat, main flow of air after secondary compression in compressor- turbine unit is directed to regenerative heat exchanger for cooling by circulating flow of room being conditioned; then it is fed to turbine for expansion and is evacuated to surrounding medium. Condensate formed due to cooling of circulating flow of air is discharged and is fed for mixing with air fed from room being conditioned before secondary cooling of main air flow. EFFECT: enhanced efficiency. 3 cl, 2 dwg
