Abstract

Desiccant humidity control has given increasing interest in the various industries like storage industry, textile industry and air conditioning industry. Compared with conventional system desiccant humidity control system saves energy by separating humidity control from temperature control and also improves the indoor air quality as a good filter. As the first step, the adsorption mechanism is explored and desiccant material properties are obtained based on a literature review. The heat and mass transfer in the desiccant moist air system is well understood and modeled. The model provides a useful tool for two purposes; analysis of desiccant unit’s performances and optimization of the design and operations of a unit. A temperature maintained strategy is proposed to improve the mass transfer efficiency. A design in which the desiccant properties are tested using the model developed before. Using the model, parametric analysis is conducted on the humidity control packed bed desiccant unit. The effect on humidity performances of processing air and thermal cycles are studied.n Three criteria are put forward to evaluate the performances of a desiccant humidity system for various applications; dry bulb temperature; wet bulb temperature and relative humidity. The systematic way is proposed to size a desiccant unit and optimize its operations. This desiccant humidity maintaining system is designed for humidity analysis and to avoid spoiling.
