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

In hot and humid regions, cooling anddehumidification are important issues of inindoor environment. In this study, theevaluation of solar-assisted desiccant airconditioningsystems utilizing periodicallyreactivated desiccant such as desiccant bedsunder hot and humid climates is performedthrough integrated building and equipmentsimulations. As a result, the periodicallyreactivated desiccant air-conditioning systemsperform with relatively higher percentage ofcomfort as well as higher primary energy COPof approximately 6.05 under not extreme highenthalpy conditions. Additionally, with theaddition of another desiccant bed, this allowsthe systems to operate during the daytime aswell as nighttime. With this double desiccantbeds system, primary energy COP of about4.97 can be achieved.
