Wang, Auteur ; X. Gao, Auteur ; J.Y. Xu, Auteur Année de publication : 2012 Article en page(s) : pp. 694–700 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Adsorption  Refrigeration  Experiment  Fluidization  Refrigerant  Specific  cooling  power Résumé : This paper proposed and designed a fluidized-bed adsorber/desorber which can be used in the adsorption refrigeration system in place of the conventional fixed-bed one. An experimental setup was built to investigate the performance of the fluidized-bed absorber/desorber and compare with that of the fixed-bed one using the working pair of activated carbon and R134a. The experimental results with 2 kg activated carbon show that the heat and mass transfer can be greatly enhanced either in adsorption or desorption in the proposed fluidized-bed adsorber/desorber The experimental results with 3 kg activated carbon show the similar enhancement, but the enhancement with 4 kg activated carbon was weakened either in adsorption or desorption due to the incomplete fluidization of the activated carbon. By way of the new approach, the poor heat and mass transfer in the conventional fixed-bed absorber/desorber can be overcome and the SCP of the adsorption refrigerator can be expected to be greatly improved accordingly.
