PROBLEM TO BE SOLVED: To suppress lowering of operation efficiency by an arrangement wherein hydrogen gas generated in an absorption refrigerating machine is not discharged to the outside but removed internally through reduction. SOLUTION: A heater holder 98 being fixed to a space communicating with a refrigerant passage comprises a base part 98b, and an oxide metal reducing part 98c held on the outer circumference thereof. A heater is inserted into the heater holder 98 and an oxide metal is heated in order to shorten the processing time. Hydrogen gas standing in the refrigerant passage touches the oxide metal to cause reduction thereof thus producing water and removing hydrogen gas. Since the water produced simultaneously with removal of hydrogen gas stands within the machine, the quantity of water being mixed into refrigerant is kept at an appropriate level. Airtightness is sustained by screwing the screw 98d of the heater holder 98 to the machine body side. |
