VAPOUR ADSORPTION REFRIGERATION : WORKINGANDDESIGN
Vapour adsorption refrigeration works on the principle of adsorption and Desorption. Adsorption and Desorption are surface phenomenon. Generally, adsorbate is adsorbed on the surface of Adsorbent, this process can be reverted by applying heat to the adsorbent. There are many adsorbate such as Methanol, Water, Ammonia and adsorbent such as activated carbon, activated carbon fiber, Silica-gel, Zeolite. The pair of adsorbent and adsorbate is called working pair. Different kind of working pair gives different results. Literature review suggests that around 0.25 to 0.5 coefficient of performance(COP) can be achieved. It has relatively low COP but it has advantage that it runs on low grade energy such as heat waste, solar energy, etc. This article include working cycle, design of components and calculation of Vapour Adsorption Refrigeration cycle.
