The paper gives the latest review on the thermodynamics modeling and the COP of vapour adsorption refrigeration system operating with one bed or double bed intermittent cycle. A detailed literature review has been carried on the principle of adsorption, properties of adsorbent-adsorbate materials, and this adsorbent-adsorbate work with vapour adsorption cycle. It was observed that the technology is very attractive, but it has limitations relating to its low coefficient of performance. A survey of new research techniques for the improvement is also shown in this paper. It showed that there were adsorption systems which can be useful for ice-making, air-conditioning, refrigeration, as stand alone or hybrids systems, but also cater to environmental protection and energy conservation.
