PURPOSE: An absorption refrigerating machine is provided to suppress a decrease in operation efficiency by removing hydrogen gas generating in an absorption refrigerating machine without releasing it to the outside. CONSTITUTION: Hydrogen gas residing in a condenser(9) is brought into contact with a metal oxide(99) in a hydrogen-removing equipment(93) provided in the condenser. Reduction of the metal oxide is induced by the contact to remove the hydrogen gas and to produce water. Since the reduction part of the hydrogen-removing equipment is provided particularly in the condenser, special sealing structure is not necessary, as compared with a refrigerating machine in which a reduction part provided in the outside of the condenser is connected by a pipe line. Besides, reduction can be generated sufficiently by using the temperature of refrigerant vapor introduced from an inlet(94) into the condenser. While an absorption refrigerating machine is running, the hydrogen gas in the condenser is reduced by contact with the metal oxide. Water is produced and the hydrogen gas is removed. Thereby, a high operation efficiency is maintained and the water content of refrigerant is kept regular. 본 발명의 목적은 흡수식 냉동기내에서 발생하는 수소가스를 외부로 방출시키지 않고 내부에서 환원제거하여 운전효율의 저하를 억제하는 데 있다. 이를 위하여 본 발명에서는 응축기(9)내에 체류하고 있는 수소가스를 응축기 (9)내에 설치한 수소제거장치(93)내의 산화금속에 접촉시킨다. 이 접촉에 의해 산화금속의 환원반응이 일어나 수소가스는 제거됨과 동시에 물이 발생된다. 특히 환원부 즉 수소제거장치(93)를 응축기(9)내에 설치하였기 때문에 응축기(9)밖에 설치한 환원부를 관로로 접속하는 것과 비교하여 특별한 밀봉구조가 불필요하고, 수납구(94)으로부터 응축기(9)내로 도입되는 냉매증기의 온도를 이용하여 충분한 환원반응을 일으키게 할 수 있다.
