ABSTRACT

The severities of energy crisis and environmental problems have been calling for rapid developments in thermally powered adsorption systems using natural and/or alternative to hydrofluorocarbonbased refrigerants. Adsorption isotherms, kinetics, and heat of adsorption data of adsorbent– refrigerant pairs are essential for designing adsorption cooling and heat pump systems. This paper presents the adsorption kinetics of ethanol onto a highly porous activated carbon fiber along with a brief overview of thermally activated adsorption cooling cycles. System outlines, theory of operation, and characteristics of multibed, multistage cycles are presented for cooling applications.
