A review on adsorption cooling systems with silica gel and carbon as adsorbents

This study presents adsorption cooling systems with silica gel and activated carbon as adsorbents. Adsorption cooling systems powered by low grade heat sources are presented here. Moreover, the previous experimental and numerical models are discussed. The study revealed that the performances of silica gel and activated carbon based adsorption cooling systems are still low and hence these systems are in the stage of demonstration and prototyping. It was concluded that there is still an opportunity for adopting more modern solar energy collecting and transferring technologies, and more advanced design optimization and simulation models. However, heat recovery, mass recovery, multi-bed and multi-stage technologies are promising technologies in improving the COP and SCP of these systems.
