Abstract:
An absorption cooling apparatus comprising:a pump for supplying in circulation an absorbing liquid of high refrigerant content;a generator for heating the absorbing liquid supplied from said pump;a gas-liquid separator with which said absorbing liquid heated with said generator is separated into an absorbing liquid of low refrigerant content and a refrigerant vapor;a heat exchanging unit for performing heat exchange between the absorbing liquid separated by said gas-liquid separator and the absorbing liquid which is yet to flow into said generator;a cooling section in which the liquid refrigerant obtained by liquefying said refrigerant vapor is dispensed onto the outer surface of a heat transfer medium circulating pipe so that the latter is cooled by the evaporation of said liquid refrigerant;an absorbing section in which the absorbing liquid of low refrigerant content supplied from said generator is dispensed to absorb the resulting refrigerant vapor; andan active solution quantity adjusting means by which the quantity of the absorbing liquid flowing out of said gas-liquid separator is adjusted in accordance with the quantity of the solution therein.
