Abstract

In this paper, solar double-effect Ammonia-Water cooling cycle is simulated. Then, the effects of parameters on the cycle efficiency including temperature of generator and condenser, and pressure of evaporators have been analyzed. Also cooling load and COP of the cycle has been expressed as a function of the aforesaid parameters. Then cities of Iran has selected as a representative of different climates, and the performance of cycle for these cities has been analyzed using the environmental and geographical conditions such as solar radiation intensity, wet and dry bulb temperature for each city. The acceptable efficiency of the cycle for the southern cities of Iran which have the high radiant intensity is a result of this work.
