Method of bringing to temperature and holding at temperature the interior of a thermally insulated enclosure with no continuous supply of energy and the associated device

A method for changing a temperature of the interior volume of a thermally insulated space to a preset temperature and maintaining it at the preset temperature using two thermochemical systems which can be connected to an external energy source. The reactor of one of the systems is heated until fully regenerated, while the other system keeps the temperature at the preset temperature; when the reactor is fully regenerated, the system comprising the regenerated reactor is used to maintain the preset temperature and the reactor of the other system is heated to regenerate it as long as it is connected to the external energy source.

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.
