Typical cycles are described, including single effect, double effect, two-stage and triple effect LiBr absorption refrigeration cycles. Stong and weak points, and research progress of different cycles are analyzed. In addition, effects of outlet temperature of chilled water, inlet temperature of cooling water, heating steam temperature, fouling coefficient, non-condensable gas, etc. on the chilling cycle performance characteristics are discussed. Existing problems of the solar LiBr absorption refrigeration technology are indicated. With the increasing development of technology and green buildings, the development prospects of solar LiBr absorption refrigeration will be excellent.
