Thermo-chemical recuperation systems, devices, and methods are provided in accordance with various embodiments. Embodiments may generally relate to the field of refrigeration and/or heat pumping. Within that field, some embodiments apply to the recuperation or recapturing of both thermal and chemical potential in a freeze point suppression cycle. Some embodiments include a method and/or system of thermo-chemical recuperation that includes creating a flow of ice and flowing a brine against the flow of the ice. Some embodiments manage the thermal and chemical potentials by mixing a dilute brine stream exiting an ice mixing vessel with an ice stream before it enters the ice mixing vessel. By controlling this mixing in a counter-flow or step-wise cross flow manner with sufficient steps, both the thermal and chemical potential of the dilute bine stream may be recuperated.

The present invention discloses a hydrate energy-storage temperature-control material and a preparation method therefor. The material includes a refrigerant hydrate and a cross-linked polymer. The preparation method comprises the following steps: first, preparing a refrigerant hydrate by using a high-pressure reactor, and conducting grinding, crushing and sieving to obtain hydrate particles; then, uniformly spraying polytetrafluoroethylene suspended ultrafine powder onto the surface of the hydrate particles by using an electrostatic spraying device, and putting the hydrate particles into a plasma instrument to modify polytetrafluoroethylene so as to allow free radicals to be formed on the polytetrafluoroethylene powder surface; finally, subjecting monomers to graft polymerization with the free radicals on the polytetrafluoroethylene surface under the irradiation of a high-pressure mercury lamp of UV lighting system to stabilize the structure of the material, preparing a final product. According to the present invention, a hydrate energy-storage temperature-control material with good stability is prepared. A method capable of preparing various types of refrigerant hydrate materials is provided. The product can give full play to the advantages of hydrate energy storage and temperature control, can be periodically used, and can be used in various fields such as building, refrigeration, etc.

A preparation method of the microcapsules for low-temperature well cementation to be used to control cement hydration heat includes: (S1) a shell material, and added into deionized water, then the resultant mixture being stirred in a thermostat water bath so as to completely dissolve it into a homogeneous and stable shell material solution; (S2) a core material and an emulsifier being put into a three-necked flask and stirred in a thermostat water bath so as to uniformly emulsify and disperse them, forming a stable oil-in-water core material emulsion, while adjusting the pH value of the emulsion with a pH adjuster; (S3) the three-necked flask containing the core material emulsion being transferred to a water bath, and then the shell material solution being dropwise added into it with stirring, after reacting, a solid-liquid mixture being poured out so as to naturally cool it to room temperature.

The invention relates to a composition comprising 50-99 wt. % of Na.sub.2SO.sub.4.10H.sub.2O and 0.1-5.0 wt. % of an alginic acid salt. Such composition may advantageously be used as a phase change material since the composition (and a pouch comprising the composition) remains flexible during the phase change. This was also the case when subjected to a high number of subsequent cycles of heating and cooling.
