Abstract
A study is conducted on the performances of a solar powered continuous-adsorption refrigerator considering two particular days as references cases, namely, the summer solstice (June 21st) and the autumn equinox (September 21st). The cooling capacity, system performance coefficient and the daily rate of available cooling energy are assessed. The main goal is to compare the performances of a solar adsorption chiller equipped with a hot water tank (HWT) with an equivalent system relying on solar collectors with no heat storage module. The daily cooling rates for the solar refrigerator are found to be 102.4 kWh and 74.3 kWh, respectively, on June 21st and on September 21st, using a total collector’s area of 43.47 m2. The corresponding values for the adsorption chiller equipped with a hot water tank of 2 m3 (and using a total collector’s area of 72.45 m2), are 127.1 kWh and 106.13 kWh, respectively.
