Technical and Economical Study on Application of Absorption Solar Chiller in Iran

Energy challenges in recent years, especially in summer and shortage of fossil fuels along with their environmental problems have caused solar energy to become an important source of energy. Solar radiation can be applied as a source of energy for cooling systems in summer. In this article, performance of solar chilling systems is studied. This system has 30 evacuated tube solar collectors and an ammonia-water absorption chiller with maximum cooling capacity of 2.5 tones. Using meteorological data, absorbed heat in different cities were calculated and absorption system was simulated using HYSYS. Finally effects of different parameters and weather conditions are studied and the cost of this system is compared to conventional compression systems.
