An experimental study on heat and mass transfer in a closed adsorbent bed of an adsorption heat pump

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.Heat and mass transfer in an adsorbent bed of an adsorption heat pump play an important role on the efficiency of the system. In this study, beat and mass transfer in an adsorbent bed of an adsorption heat pump is experimentally investigated during the isobaric adsorption process. An experimental setup was constructed and silica gel-water pair was chosen as working pair. By using the obtained experimental data during the adsorption process, the amount adsorbed, pressure change in the adsorbent bed and in the evaporator, the evaporator temperature and the temperature profile along radius of the adsorbent bed are shown via graphics, and necessary discussions are performed.
