2117773 9321485 PCTABS00027 A regenerative absorption cycle using a super-pressure boiler to achieve a high coefficient of performance. An ammonia/water solution is boiled in high-pressure boiling conduit (66). Boiled-off high-pressure ammonia vapor is condensed (96), expanded to low-pressure (99), and boiled in evaporator (101) to extract heat from a refrigerating fluid going to cooling load (104). Low-pressure ammonia vapore from evaporator (101) returns to regenerator (28) and is absorbed back into low-pressure liquid. The low-pressure solution from regenerator (32) is then cooled in absorber (56) to reject heat from the cycle and is then pumped (58) back to the high-pressure boiling conduit (66). The liquid solution from high-pressure boiling conduit (66) is pumped up to an externally-heated super-pressure boiler (11). Ammonia vapor from boiler (11) is absorbed back into super-pressure liquid in conduit (26), which functions as an internal heat source to heat the high-pressure boiling conduit (66). Solution from conduit (26) is expanded (36) to boil in high-pressure conduit (38).
