Abstract: A split solid adsorption cooling system is disclosed. The split solid adsorption cooling system includes a first adsorption unit, a second adsorption unit, and a shell-and-tube heat exchanger. The first and the second adsorption units are connected to each other via a first pipeline and a second pipeline of the shell-and-tube heat exchanger.

Furthermore, as the shell-and-tube heat exchanger is separate from the first and the second adsorption units, the overall system volume is reduced.

The exothermic phase of the LT phenomenon takes place in a condenser in communication with the reactor in which the HT phenomenon takes place, the condensed fluid G then being transferred to the reactor in which the endothermic phase of the LT phenomenon takes place.

Abstract: A two-liquid absorption refrigerator or space cooler of the cyclic type uses a spiral shaped Bourdon Tube as the refrigerant gas generator, with the lower end of the spiral disposed at a heat source. The generator may also function as the absorber vessel, thus greatly simplifying the operation of the device. In use, when ammonia depletion during the cooling cycle allows the generator to heat, it moves its lower end to a position removed from the heat source and begins to cool, thus allowing a charging cycle to replenish ammonia into the absorption liquid (usually water) in the generator. The device may thus function with only one moving part and without electricity, and further without control over the heating source.
