Document Type and Number:
Japanese Patent JP2517337
Kind Code:
B2
Abstract:
PURPOSE:To have high corrosion resistance on the surface of steel and prevent the production of hydrogen gas in the time of corrosion to the utmost by forming a Fe3N layer and/or a Fe4N layer on the surface of steel which comes in contact with absorbent solution in regard to an absorption refrigerator in which water is made refrigerant and lithium bromide is the absorbent solution. CONSTITUTION:Water is made into refrigerant, and lithium bromide into absorbent solution; in regard to an absorption refrigerator using steel on a part with which the solution comes in contact, a Fed3N layer and/or a Fe4 layer are formed on the surface of steel which comes in contact with an evaporator 1, an absorber 2, a high temperature and a low temperature generators 3, 4, a condenser 5 and each piping 6-13. As the result, since the surface of steel which comes in contact with the absorbent solution gas very high corrosion resistance, the production of hydrogen gas can be prevented in the time of corrosion. Therefore, a refrigerator for lessening the number of air bleed, can be obtained.
