The present invention concerns a method of refrigerating a housing to a target temperature according to which: Characteristically, at least n&#x3e;1 other thermochemical reactors are provided;

Method for refrigerating an isothermal box to a target temperature and associated facility

Disclosed is an installation for generating electricity from a heat source, for disconnecting the production of electricity from the source of heat. The main characteristic of such installation is that it includes a thermochemical storage device coupled to a power cycle, the storage device consisting of a reactor in which produces a reversible sorption process and an evaporator and a condenser, at least one of the components of the thermochemical device being coupled mass and/or thermal to at least one element of the power cycle.

Electricity production facility including heat storage

A system for purifying a treated liquid, including:

System and method for purifying liquid by reverse osmosis

An installation for the production of cold and/or heat has a driving and a receiving machine. The driving machine has means for circulating a working fluid G, an evaporator E, at least one transfer cylinder CTthat contains a transfer liquid LT in a lower part and the working fluid Gliquid and/or vapor form above the transfer liquid, a condenser C, at least one device BSfor separating the liquid and vapor phases of the working fluid G, and a device for compressing the working fluid Gto the liquid state. The receiving machine has means for circulating a working fluid G, a condenser C, at least one device BSfor compressing or expanding and separating the liquid and vapor phases of the working fluid G, optionally a pressure reducer D, an evaporator E, and at least one transfer cylinder CTthat contains the transfer liquid LT in a lower portion and the working fluid Gin liquid and/or vapor form above the transfer liquid; the transfer cylinders CTand CTare connected by at least one pipe that can be blocked by actuators and in which only the transfer liquid LT can circulate.

Installation and method for the production of cold and/or heat

A plant for the producing of cold, heat and/or work. The plant includes at least one modified Carnot machine having a first assembly that includes an evaporator Evap combined with a heat source, a condenser Cond combined with a heat sink, a device DPD for pressurizing or expanding a working fluid GT, a means for transferring said working fluid GT between the condenser Cond and DPD, and between the evaporator Evap and DPD; a second assembly that includes two transfer vessels CT and CT' that contain a transfer liquid LT and the working fluid GT in the form of liquid and/or vapor; a means for selectively transferring the working fluid GT between the condenser Cond and each of the transfer vessels CT and CT&#x2032;, as well as between the evaporator Evap and each of the transfer enclosures CT and CT&#x2032;; and a means for selectively transferring the liquid LT between the transfer vessels CT and CT&#x2032; and the compression or expansion device DPD, said means including at eat hydraulic converter.

Plant for producing cold, heat and/or work

The invention relates to a thermochemical device and to a method for producing refrigeration at very low temperature. The device produces refrigeration at a temperature T&#x3c;&#x2212;20&#xb0; C., from an available heat source at a temperature Tof 60-80&#xb0; C. and a heat sink at the ambient temperature Tof 10&#xb0; C.-25&#xb0; C. It comprises two coupled dipoles, operating in phase opposition. The thermochemical phenomena in one of the dipoles are such that this dipole may produce refrigeration at Twith a heat sink at the ambient temperature T. The thermochemical phenomena in the other dipole are such that this dipole may be regenerated from the heat source Tand a heat sink at the temperature T.
