TRANSIENT-BEHAVIOR OF AN ADSORPTION REFRI GERATOR - EXPERIMENTAL-STUDY OF THE ALCOHOL ACTIVATED CARBON SYSTEM/

The objective of this article is to present an experimental study of a n adsorption refrigerator, accounting for the transient phenomena in e ach component of the machine, in particular in the adsorber. The coupl es adsorbate/adsorbent investigated (activated carbon/methanol or etha nol) have been chosen on the basis of an earlier comparative study. We have performed a full series of experiments to investigate the transi ent evolution of temperatures, pressures and the cycled mass, in a dis continuous cycle, and along the components of the refrigerating machin e. The influence of various parameters is studied by varying one at a time : adsorbate/adsorbent couple, alcohol load in adsorber, alcohol f lowrate, heating power, initial desorption temperature. All these expe rimental observations are discussed and compared to transient models d eveloped in a separate article.
