The paper proposed an optimised resorption cogeneration with a stabilisation unit and effective mass and heat recovery to further improve the performance of the original resorption cogeneration first proposed by Liwei Wang et al. It combines the ammonia resorption technology and expansion machine to utilise low grade heat such as solar energy or waste heat for continuous and simultaneous production of refrigeration and electricity. It has been theoretically proved competent to improve the overall exergy efficiency by 40%-60% compared with Goswami cycle under the same working conditions. In this work, a buffer was designed to place before the expansion machine to mitigate the dramatically varying reaction rate, and two sets of resorption cycle were arranged to overcome the intermittent performance of the chemisorption. The cycle was investigated based on the first and second law of thermodynamics using Engineering Equation Solver. Twelve resorption working pairs of salt complex candidates were analysed under different working conditions. The energy and exergy analysis identified the ideal working pair among the chosen working pairs under the driven temperature from 373K to 473K.
