Vapour compression refrigeration systems are characterised by relative high energy requirement in addition to environmental pollution tendencies. Adsorption refrigeration system could be a better option in terms of huge energy savings and carbon emission reduction. This study is aimed at evaluating the performance and characteristics of date-seed activated carbon (DSAC) for use as adsorbent in adsorption refrigeration. Using isoster-based adsorbent/adsorbate equilibrium test rig, pressure, temperature and concentration (P-T-X) data were obtained. The isosteric heat of adsorption for conventional activated (CAC) and DSAC are estimated to a first approximation to be 16.058 and 16.650 kJ/Kg respectively. The results showed that date-seed activated carbon has relatively good adsorptive characteristics.
