Title: Absorption refrigerator with pressure compensating inert gas - has gas circuit evaporator with vertical tube and internal baffles for downward flowing liquid refrigerant
Inventor: EBER NICOLAS DR SC TECHN
IPC: F25B15/10
Filed: 1974-10-17
Abstract: Refrigerator operates with pressure compensating inert gas whose liquid circulation incorporates an absorber, and whose gas circuit incorporates an evaporator. The evaporated refrigerant is transported by the inert gas from the gas circuit to the liquid circulation system and the refrigerant vapours are absorbed within the absorber in a depleted absorber solution. This arrangement is improved by using as an evaporator a vertical tubular element whose inner wall is equipped with a helical wire coil which divides the downwards flowing liquid refrigerant. The vertical tubular absorber is connected to the base of the vertical tubular element and has helical internal baffles. For downwards flowing absorption solutions the vertical tubular element has a concentric internal tube which reaches into the absorber and these components form flow paths within the gas circulation through the evaporator, the heat exchanger and the absorber.
