Abstract

In the present study, water vapor adsorption onto silica-gel, activated carbon powder (ACP) and activated carbon fiber (ACF) has been experimentally measured at 20 °C, 30 °C and 50 °C. The adsorption data is fitted with Guggenheim-Anderson-De Boer and Dubinin-Astakhov adsorption models for silica-gel and ACP/ACF, respectively. Steady-state moisture cycled (MCSS) is determined for greenhouse demand category-I, II and III which are based on 60%, 40% and 20% relative humidity of dehumidified air, respectively. The ACP and ACF enable maximum MCSS for demand category-I and II, respectively. However, the silica-gel is found the only applicable adsorbent for demand category-III.
