Title:
HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2022/152934
Kind Code:
A1
Abstract:
The invention relates to a heat pump that can be used for heating, cooling such as refrigeration and/or freezing, notably in applications involving large temperature differences, such as domestic or industrial refrigeration/freezing, domestic or industrial heating, or improving the efficiency of thermodynamic machines. The heat pump removes heat through a first exchanger 6 to a hot source and collects heat through a second exchanger 4 from a cold source. The working fluid is made to circulate by a compressor 2, and expansion is performed through a first motor 1 which decreases the energy needed for the operation of the compressor 2 A second motor 3 provides the energy needed for the operation of the compressor 2, decreased by the proportion of energy supplied by the first motor 1. A third exchanger 5 preheats and precools the working fluid through reciprocal heat exchange. Also provided is a heat-collecting circuit, and the first motor 1 further comprises a fourth exchanger having an inlet and an outlet allowing a working fluid that circulates in this hydraulic heat-collecting circuit to pass through this fourth exchanger.
