Abstract:
1. A gas absorption space cooler/refrigerator comprising: a generally spiral, substantially tubular generator-absorber chamber having upper and lower check valves, the upper check valve oriented to allow gas to flow out of the generator-absorber chamber but not in, the lower check valve oriented to allow gas to flow into the generator-absorber chamber but not out, the generator-absorber chamber made of a material sensitive to internal pressure within the generator-absorber chamber; whereby when a first level of pressure is present in the generator-absorber chamber the generator-absorber chamber assumes a first spiral shape, and when a second level of pressure is present in the generator-absorber chamber the generator-absorber chamber assumes a second shape, a first portion of the generator-absorber chamber disposed at a first location when the generator-absorber chamber assumes the first spiral shape and disposed at a second location when the generator-absorber chamber assumes the second shape; a heat source disposed at the first location, the heat source in thermodynamic communication with the first portion of the generator-absorber chamber; a condenser fluidically communicating via the upper check valve with the generator-absorber chamber, the condenser having an expansion valve; an evaporator fluidically communicating via the expansion valve with the condenser, and further fluidically communicating via the lower check valve with the generator-absorber chamber.
