Summary: Demand of the humidity control has increased rapidly to have a comfortable space and a safety for a food processing plant. The paper presents a brief review of the systems for dehumidifying and humidifying, and the significance to control humidity and temperature independently for energy saving. It is suitable to apply the absorption and adsorption process to the humidity control. Moisture transportation mechanism in the sorption process was explained. Some studies of the desiccant elements and hybrid systems those are composed of adsorption chiller and desiccant dehumidifier are introduced. The hybrid system can be driven by the thermal energy at temperature of 55 deg.C and the energy efficiency improved 30% compared with the cooling dehumidifier system..

Summary: Precise information such as local temperature, humidity and amount of adsorbed water in a desiccant rotor is significant to improve the rotor and system performance. The paper presents a theoretical dynamic analysis model of heat and mass transfer in a rotor to clarify the design aspects and performance of high efficient systems. The influences of rotor speed, adsorption/desorption time ratio, airflow path patterns and air conditions on rotor performance are discussed. There is an optimum angle of each process zone and an optimum desorption side air flow rate becoming a maximum amount of adsorption. Hybrid system composed of a vapor compression cooling system and desiccant dehumidifier has the potential to improve COP value up to 24% compared with non-hybrid system..
