Thermodynamic analysis of ammonia-water absorption refrigeration cycle

The ammonia-water single stage absorption refrigeration cycle has been studied by the methods of simulated. And the affection of process parameter vs character of cycling has been analyzed also. The affection of the theoretical plate number in the rectifying tower vs cycle efficiency is gradually moved up, and then tend to be horizontal. The affection of the cooling temperature linearly drops. The maximum value of the affection is respectively existed from reflux ratio and the temperature of high-temperature side in the rectifying tower. It has been discovered in the research of heat integrated cycles that the increase of the number of tower kettle exchanger and vaporization one can improve the efficiency. The effect of the former is more apparent.
