Abstract: This study investigates the performance of a hybrid passive cooling system that combines a hydronic radiative cooling (RC) panel integrated with a cross-flow dew-point indirect evaporative cooler DPIEC equipped with a closed cycle water reclamation using air-water harvesting (AWH) system. The study was performed on a typical residential house located in the hot and mostly dry climate of Kuwait. The house hourly cooling load was calculated using the transient simulation software TRNSYS. A mathematical model integrating the hydronic RC panel and the DPIEC models was developed and simulated to predict the system operation over the cooling season. The integrated hybrid system’s performance was compared with two systems: i) the DPIEC unit standalone, and ii) the conventional cooling system, while focusing on the role of the RC system.
