FIELD: heating.
SUBSTANCE: method of heat pump heat supply provides for conversion of low-potential thermal energy with the help of heat pump equipment. Conversion of energy is carried out in heat pump equipment, adapted to temperature modes of generated thermal energy and a used source of low-potential thermal energy, due to realisation of a double-staged or single-staged thermodynamic cycle of energy conversion, depending on difference of temperatures of a source of low-potential thermal energy and generated thermal energy. Generation of thermal energy of increased temperature potential, for instance, for needs of hot water supply, is carried out in priority order in the double-staged mode, afterwards in the single-staged mode they generate thermal energy for other engineering systems of the building.
EFFECT: increased energy efficiency of heat pump heat supply.
