Title

Analytical assessment of the desiccant enhanced radiative cooling concept

Abstract

This paper provides a limited analytical feasibility assessment of the desiccant enhanced nocturnal radiation (DESRAD) cooling and dehumidification concept. This concept integrates the moisture exchanging capacity of a roof plenum desiccant system with radiative cooling potential of the night sky and the thermal and moisture capacity of building materials to provide a high efficiency, daily-cycle cooling and dehumidification system for buildings. The paper presents the modeling methodology and results from an analysis of the DESRAD system in Miami, FL and Atlanta, GA. The model accounts for the interaction of the building and the DESRAD system by coupling a combined heat and mass transfer model for the building and a pseudo steady-state desiccant model for the DESRAD system. Results show summer day electrical cooling savings of 65% and 78% for Miami and Atlanta, respectively. Peak electrical demands over a five hour period from noon to 5 p.m. were also reduced by 20% in Miami and 60% in Atlanta.
