Analysis and optimization on thermodynamic performance of the ammonia-water absorption power/cooling integrated cycle driven by mid- or low-grade geothermal energy were conducted in this study. Based on the Kalina cycle, by applying the evaporation characteristic of ammonia-water, the forward power sub-process was combined with the reverse refrigeration sub-process, which realized the hybrid generation of power and cooling capacity simultaneously. Four main parameters were analyzed on their effect on the thermal performance of the integrated cycle, including the working fluid concentration xw/xb, ammonia dew-point temperature t14, circulation ratio K, and chilling fraction n. The result showed that under the optimal condition, (xw/xb=0.50/0.32, t14=180℃, K=2.80 and n=0.505), the thermal efficiency of the integrated cycle could reach up to 19.38%, which is 3.71% higher than that of ammonia-water power cycle and 8.54% than that of Rankine cycle, repectively. Besides, the integrated cycle presented much higher exergy efficiency of 59.77% comparing with the other two cycles.
