BEHAVIOUR OF A RECTANGULAR ADSORBER OF SOLAR ADSORPTION COOLING MACHINE

摘要

This paper presents the study of a rectangular adsorber of solar adsorption cooling machine. The modelling and the analysis of the adsorber are the key point of such studies, because of the complex coupled heat and mass transfer phenomena that occur during the working cycle. The adsorber is heated by solar energy and contains a porous medium constituted of activated carbon AC-35 reacting by adsorption with methanol. The simulation technique takes into account the variation of ambient temperature and solar intensity along a simulated day, which is corresponds to a total daily insolation of 26,12 MJ/m~2 and an average ambient temperature of 27.7 °C. The obtained solution allows to know the daily thermal behaviour of the rectangular adsorber. The model is used to study the influence of the solar collector type on the system’s performance.
