Title: Absorption type refrigerating machine
Inventor: YURI NOBUYUKI
IPC: F25B43/04
Filed: 2000-04-19
Abstract: PROBLEM TO BE SOLVED: To suppress the decline of the operating efficiency of an absorption type refrigerating machine without discharging the hydrogen gas generated in the machine by removing the gas in the machine through reduction. SOLUTION: In the inner upper part of an absorber 2, a hydrogen treating device 21 is positioned adjacently to an evaporation passage 20a by making an evaporator 1 communicate with the absorber 2. The device 21 is filed up with a metal oxide and the hydrogen gas generated in a refrigerant passage reacts to the metal oxide and produces water, resulting in the removal of the hydrogen gas. Since the refrigerant vapor generated in the evaporator 1 shifts from a low-temperature environment to a high-temperature environment, there is no possibility of a condensed refrigerant adhering to the hydrogen treating device 21 adjoining to the evaporation passage 20a. Therefore, the hydrogen removing treatment can be promoted without lowering the reaction efficiency of the metal oxide even when the refrigerating machine is in an operating state.
