Abstract: The present study aims to investigate theoretically with the model validation from the measured data, the operation and design parameters and the effect of the coupled heat and mass transfer mechanisms within a system of adsorber, containing plate and tube heat transfer core, which on its surface the adsorbent immobilized by an adhesive agent. The case study is to estimate the maximum adsorption capacity of activated carbon granules/R-134a adsorption refrigeration working pair where a measurements shows they has a high adsorption capacity value. The study investigate the effect of operating parameters on the adsorption and desorption process such as temperatures, heating and cooling water mass flow rates as well as the design parameters such as the fin numbers, and adsorbent material data such as mean diameter, pore diameter and specific surface area per unit mass on both adsorber size and performance. Also, at different adsorption temperatures of 25, 30, 35 and 50 °C using plate and tube adsorber heat transfer core
