It is possible to create differential temperature between the two ends of an adsorbent column with quick and sequential inflow and outflow of adsorbate. Being able to generate heating and cooling at the two extremities of the same tube, simultaneous rejection of heat of adsorption to heat sink and retrieval of cooling from heat of desorption, can be achieved in a single tube. Since the production of continuous sorption cooling is not compulsorily related to use of multiple beds and connecting them to heat sink and heat source in alternative cycles, operational hazards are substantially less in this new process. Interestingly, presence of an orifice at the hot end of the column can significantly magnify the temperature difference between the hot and cold ends. Systematic experimental study relating both operating variables and geometrical parameters has been carried out. Generalised and in-depth theoretical analysis involving transient heat and mass transfer equations has been performed. Thermo-hydraulic behaviour within the bed could be explained reasonably well with the theoretical modelling. Afterwards, effects of particle diameter and bed porosity on the cold end performance have been studied theoretically. (c) 2014 Elsevier Ltd. All rights reserved.
