HEAT AND COLD SUPPLY METHOD Russian patent published in 2013 - IPC F25B29/00 

FIELD: heating.

SUBSTANCE: coolant after condensation is divided in a vortex into steam and supercooled liquid phases due to difference of pressures of condensation and suction, at the same time steam is sent for compression jointly with vapours from an evaporator, a small portion of supercooled liquid phase is sprayed and supplied into the suction tract of the compressor in the amount providing for minimum reheating of vapours in the end of compression, and the main flow of supercooled coolant is supplied into the evaporator.

EFFECT: invention makes it possible to reduce specific costs of external energy for transfer of a heat unit compared to other reverse cycles and to increase coefficient of heat pump transformation.
