Abstract

In this study, a desiccant outdoor air-conditioning system that uses high-temperature chilled water (approximately 20 °C) and low-temperature hot water (approximately 55 °C) produced by a high-efficiency heat pump, and hot air produced by solar heat collectors, was proposed. This system treats the total heat load of outdoor air and indoor latent heat load in commercial buildings. In the proposed system, solar heat is effectively used for regeneration of the desiccant in summer and for pre-heating of ventilation air in winter. We have constructed a prototype of this system and evaluated the coefficient of performance (COP) of the entire desiccant air-conditioning system using the measured values of electric energy consumption and treated enthalpy between the outdoor air and supply air.
