Absorption refrigeration method and apparatus

Abstract From the Canadian patent

In an absorption refrigeration process which includes the steps of heating a dilute absorbent solution in a first phase to drive off a diluent to form a concentrated absorbent solution and condensing the diluent and delivering same to a second phase to remove heat from a refrigeration load and reabsorbing the diluent in the concentrated absorbent solution to thereby form a diluted absorbent solution for return to said first phase, the improvement comprising: maintaining a pressure within said first phase equivalent to the pressure in the second phase so as to minimize absorbent solution temperature differences and eliminate diluent temperature differences; and, storing functionally …
