Abstract:
1. A reversible system for recovery by sampling and transfer of energy between at least two different media, or between an outside medium and a biotope or between a biotope and another biotope, by using as a vehicle a refrigerating fluid that passes successively from a gaseous state to a liquid state and vice versa by a succession of phases of compression and expansion, comprising: at least one primary compressor (CP a capillary CAPILLARY an exchanger E a bi-flow thermostatic expansion valve D a capillary CAPILLARY the fluid/fluid exchanger E said fluid/fluid exchanger E said refrigerating fluid reservoir R that contains a refrigerating fluid reserve, said nonreturn valve C a nonreturn valve C a motorized three-way valve V a motorized three-way valve V a solenoid valve VEM a solenoid valve VEM a simple-flow expansion valve D
