Evaluation of the solar-assisted desiccant air-conditioning systems using periodically reactivated desiccant beds under hot and humid, climates

摘要

In hot and humid regions, cooling and dehumidification are important issues of in indoor environment. In this study, the evaluation of solar-assisted desiccant air-conditioning systems utilizing periodically reactivated desiccant such as desiccant beds under hot and humid climates is performed through integrated building and equipment simulations. As a result, the periodically reactivated desiccant air-conditioning systems perform with relatively higher percentage of comfort as well as higher primary energy COP of approximately 6.05 under not extreme high enthalpy conditions. Additionally, with the addition of another desiccant bed, this allows the systems to operate during the daytime as well as nighttime. With this double desiccant beds system, primary energy COP of about 4.97 can be achieved.
