Absorption technologies using lithium bromide-water and water-ammonia systems are fairly well developed and have already been in use for many years. Adsorption technologies have been used extensively for separation and purification of gases for the past few decades but their exploitation for refrigeration and heating purposes is rather recent. The advantage of adsorption cooling system is that they can be driven by low-grade energy such as waste heat or solar energy. In an adsorption refrigeration system, the critical component is sorption bed where adsorption and desorption of adsorbate from adsorbent take place. Effective performance of an adsorption refrigeration system depends on how effectively desorption and adsorption occur at selected temperatures. It is planned to study desorption and adsorption characteristics of different working pairs theoretically. It is expected that this study would help to identified right working pairs suitable for particular applications and operating conditions. In this project, a thermodynamic analysis of sorption bed has been carried out.
