A small scale solar powered adsorption cooling plant has been constructed in Assiut University, Egypt. The plant consists of evacuated tube solar collector arrays of area 36 m2 with high reflective parabolic surface used at the back, a silica gel-water adsorption chiller of 8 kW nominal cooling capacity, and hot and cold water storage tanks of 1.8 and 1.2 m3 in volume, respectively. Field test results from June to September 2012 showed that under daily solar insolation varies from 21 to 27 MJ/m2, the solar collectors employed in the system have higher and constant thermal efficiency during the day. The performance analysis of the adsorption chiller showed that the chiller average daily COP was 0.41 with average chilling power of 4.4 kW when the cooling water temperature was about 31 ˚C and chilled water temperature of 19 ˚C. Using the city water of temperature about 27.7 ˚C as cooling medium enhanced the chiller COP by 40 % and the chilling power by 17 %.
