Abstract
A refrigerating machine including an evaporator section, absorber section, condenser section and a regenerator section respectively divided into two stages. The first evaporator stage and second evaporator stage are arranged so as to be enclosed by the first absorber stage and the second absorber stage, with the first absorber stage being combined with the first evaporator stage and the second absorber stage being combined with the second evaporator stage to respectively form separate units. The first low temperature regenerator stage and the second low temperature regenerator stage are arranged so as to be enclosed by the first condenser stage and the second condenser stage, with the first condenser stage being combined with the first low temperature regenerator stage, and the second condenser stage being combined with the second low temperature regenerator stage to respectively form separate units. Flow passages for chilled water and cooling water create an efficient heat transfer in the divided evaporator, absorber and condenser sections, with a flow of cooling water flowing into the absorption type refrigerating machine being reduced and overall efficiency of the refrigerating machine being increased.
