FIELD: heating.
SUBSTANCE: cycles of transformation of the spent thermal energy, systems and devices use some heat exchangers of the spent energy located in series in spent heat flow and several thermodynamic cycles, parallel to heat exchangers of spent heat, to provide maximum extraction of heat energy from spent heat flow by means of working fluid medium. Parallel cycles operate in various temperature ranges with lower temperature working yield which is used for actuating of the working fluid medium pump. The working fluid medium mass control system is integrated in cycles or joined with them.
EFFECT: invention allows to provide the maximum extraction of heat energy from spent heat flow by means of working fluid medium.
