Disclosed is an adsorption-based heat pump useful for refrigeration and cooling/heating for applications such as HVACs and chillers. Adsorption is a surface phenomenon where a solid substance (adsorbent) attracts molecules of a gas or solution (refrigerant or adsorbate) on its surface. The latent heat of the adsorbate provides the heating/cooling effect. The novel adsorption heat pump enhances heat and/or mass transfer to and from the adsorbate. One embodiment comprises at least one evaporator, at least one desorber (adsorbent heating apparatus), at least one adsorbent cooling apparatus and at least one condenser. The embodiment employs different techniques to enhance heat and/or mass transfer.

The present invention relates to a method for getting the interior volume of a thermally insulated space (5) up to temperature and maintaining it at temperature using two thermochemical systems (TCU1; TCU2). According to the invention, a suitable device is supplied and steps are taken to ensure that all the fluid of each of said systems (TCU1; TCU2) is contained in the reservoir (1; 2) of each of said systems (TUC1; TCU2); at least one of said systems (TCU; TCU2) is used to bring said space to a setpoint temperature, a) the reactor (15; 25) of one of said systems (TCU1; TCU2) is heated until fully regenerated, while the other system (TCU1; TCU2) keeps the temperature at said setpoint temperature; b) when the reactor (15; 25) is fully regenerated, said system comprising the reactor that has just been regenerated is used to maintain the temperature and the reactor (15; 25) of the other system (TCU1; TCU2) is heated long as said connection means are connected to said external energy.

A system for obtaining a desired cooling effect that utilizes a water-soluble endothermic salt solution and pure water. The cooling effect is created by cycling between two phases, a refrigeration phase and a dehydration phase. In the refrigeration phase, a water-soluble endothermic salt solution is used as a refrigerant to absorb heat by pumping through a first heat exchanger which cools an object or an area. In the dehydration phase, the cooling process is regenerated by pumping the now heated endothermic salt solution through a distillation membrane, where the solution and pure water are continuously commingled and separated from one another through a distillation membrane to optimize the thermodynamic efficiency of the system. At least two pumps provide the motive energy to move the endothermic salt and pure water through the closed loop piping system. The concentrated salt solution leaving the distillation membrane is further cooled using a second heat exchanger to facilitate crystal formation. Once crystal formation occurs, pure water is added back to the concentrated salt solution to restart the refrigeration phase, and thus, the cooling process.

A method for generating electricity and cold and a device for realizing same, consists in a closed absorption cycle in which a working body is a mixture of a low-boiling (refrigerant) component and a high-boiling (absorbent) component. The method involves evaporating a strong solution in a steam generator, thus forming a refrigerant vapor and a weak solution, expanding the refrigerant vapor in a turbine, thus producing work, and, after the turbine, absorbing spent vapor in an absorber, forming a strong solution. A distinguishing feature of the method consists in changing the concentration of a strong solution using two stages, including not only evaporation but also filtration. The proposed method and device allow for significantly increasing the efficiency of systems for generating electricity relative to analogous known methods.
