| Solar energy applications in Iran for supplying domestic hot water, space heating and cooling have Attracted considerable attentionin last decade. In this paper, a solar absorption chiller is designed to serve asa common typical office building in Tehran with floor area of 1300 m^2. Moreover, the rate of solar absorption chiller energy consumption in comparison with conventional absorption chillers is considered. The daily cooling system schedule is considered during May 5 to October 7 from 8:00 to 17:00. This study demonstrates that the single effect absorption chillers with hot water supply and solar evacuated tube collector for cooling application are the most significant compatible and suitable chillers and solar collectors. The power of this absorption chiller’s generator is 236 kW, of which 41% is supplied by evacuated tube collectors. Achieving this purpose requires utilizing 104 collectors which everyone compromises of 22 tubes with total absorber area of 184 m^2. With this replacement the investment payback rate would be 10.5 years. |
