Disclosed is a refrigeration system, including: a generator having a liquid storage cavity for containing a liquid ammonia and sodium nitrate solution, a heat source being connected to the generator and an exhaust pipe being arranged at the upper end of the generator; a condenser having a condensation cavity, an inlet of the condensation cavity being communicated with the exhaust pipe; an evaporator having an evaporation cavity for containing hydrogen, an inlet of the evaporation cavity being communicated with an outlet of the condensation cavity through a liquid inlet pipe; an absorber located below the evaporation and having an absorption cavity for containing a sodium nitrate solution, an upper part of the absorption cavity being communicated with an outlet of the evaporation cavity through a mixed gas pipe, and the absorber being provided with a reflux pipeline which communicates the absorption cavity and the liquid storage cavity.

The present invention presents a thermochemical energy storage system. The system includes a membrane-based thermochemical reactor. The reactor includes a solution channel having an absorbent-containing solution flowing therethrough and a refrigerant channel having a refrigerant flowing therethrough along with first and second fluid channels. A porous membrane is positioned between the refrigerant channel and the solution channel; the porous membrane permits flow of vapor molecules therethrough while restricting flow of absorbent molecules. The system further includes a solution storage repository in fluid communication with the solution channel and a refrigerant repository in fluid communication with the refrigerant channel. The system can be used in high-density, high-efficiency, and low-temperature energy storage systems. The membrane-based reactor offers a large specific surface area and integrates solution/refrigerant flows, which enables formation of a highly compact reactor exhibiting strong heat/mass transfer. In some embodiments, direct diffusion of water molecules through the membrane makes it possible to lower the required charging temperatures.

A heating and cooling system powered by renewable energy and assisted with geothermal energy includes a solar cycling unit, a supercritical carbon dioxide (S—CO.sub.2) unit, and a refrigerant cycling unit. Solar energy obtained at the solar cycling unit may be used to power the S—CO.sub.2 cycling unit. To do so, the solar cycling unit utilizes a solar collector, a thermal energy storage, and a heat exchanger along with a first working fluid which is preferably molten salt or Therminol. Next, the energy generated at the S—CO.sub.2 cycling unit, which preferably circulates S—CO.sub.2 as a second working fluid, may be used to operate the refrigerant cycling unit. In the refrigerant cycling unit, Tetrafluroethene is preferably used as the third working fluid to produce required cooling effects. Additionally, geothermal heat exchangers may be integrated into the system for use during varying weather conditions.
