Absorption type refrigerator

摘要

For minimizing declination of the operational efficiency, hydrogen gas generated in an absorption type refrigerator is eliminated by reduction without exhausting to the outside. The hydrogen gas H2 remains close to the level surface 93 of a refrigerant in a condenser 9 is transferred together with a refrigerant vapor via an extraction pipe 92 to a condenser tank 91. The condenser tank 91 is equipped with a heated metal oxide which is allowed to come into direct contact with the hydrogen gas for carrying out its reduction. Accordingly, the hydrogen gas is eliminated and a trace of water is generated. The water is then returned back via the extraction pipe 92 to the condenser 9. As a result, the elimination of the hydrogen gas is successfully carried out while the water generated stays in the system, whereby the content of water in the refrigerant can be maintained to a desired level.
