Abstract
In an absorption refrigerating apparatus (18) the pump pipe (42) is made of a material, which is more corrosion resistant to the working medium than the material of the rest of the apparatus. In order to prevent galvanic corrosion in the boiler the pump pipe (42) can be electrically insulated (72, 74) from the rest of the boiler.
Claims6
Absorption refrigerating apparatus (18) of steel, where
- a dissolvable refrigerant by means of an absorption liquid, circulates through in turn a boiler (36) where refrigerant is liberated from the absorption liquid;
- a condenser (50) where the refrigerant condenses;
- an evaporator (16) where the refrigerant evaporates;
- an absorber (60) where the refrigerant is absorbed by the absorption liquid, and
- an absorber vessel (32) for collecting the absorption liquid, from which absorber vessel (32) the absorption liquid circulates back to the boiler (36), where the absorption liquid is heated in a pump pipe (42) so that the refrigerant is again liberated from the absorption liquid, characterized in that the pump pipe (42) is made of a more corrosion resistant material, than the steel material used in the condenser (50), the evaporator (16), the absorber (60) and in the absorber vessel (32), and that in the boiler (36) there are no joints between different materials, which can cause galvanic corrosion.
