FIELD: refrigeration equipment.
SUBSTANCE: cryogenic heat pump (10) for a device of liquefied gas processing includes in a closed circuit compressor (12), expansion device (14), first cold reception circuit (16) passing between the specified compressor and the specified expansion device. Second cold transfer circuit (18) passes between the specified expansion device and the specified compressor. The specified closed circuit contains cryogenic fluid made with the possibility of being in a two-phase state in at least part of this circuit. The specified second cold transfer circuit is made with the possibility of having an outlet temperature below -40°C.
EFFECT: possibility of recovery of energy resulting from the change of a state between a two-phase state and steam during the passage of an evaporator.
