    Patent number: 4462222
    Abstract: A dilute solution producing system of an absorption refrigerating apparatus wherein spraying of a solution and absorption of a refrigerant gas into the solution take place in a plurality of stages to produce a solution of low concentration. A solution of high concentration is sprayed in a zone of cooling water of high temperature in an absorber and the refrigerant gas is absorbed into the sprayed solution to produce a solution of intermediate concentration, and the solution of intermediate concentration is sprayed in a zone of cooling water of low temperature and the refrigerant gas is absorbed into the sprayed solution to produce a dilute solution as desired.
