Analysis of a Direct Radiation Solar Dehumidification System

Research output: NRELTechnical Report

Abstract

SERI researchers investigated a desiccant dehumidifier that is regenerated by direct absorption of solar radiation using a simplified numerical model (DESSIM) of the adsorption and desorption processes. This paper presents estimates of the performance of a solar-fired air conditioning system (ventilation cycle) containing the dehumidifier/collector. The researchers also considered the effects ofdehumidifier NTUs, heat exchanger performance, and insolation levels. The direct radiation system can operate effectively at low insolation levels and thus may have some advantages in some geographic areas.
