Title

Description of an indoor test facility for evaluating a roof integrated cooling concept

Abstract

An advanced roof test facility has been designed, constructed, and made operational at the Florida Solar Energy Center. The facility is called the Diurnal Test Facility and was designed to provide data which could be used for verification and improvement of the analytical model of the desiccant enhanced radiant cooling (DESRAD) concept. The effects of solar heating potential and nocturnal cooling potential are simulated in a controlled indoor environment and measurements are made along and between the boundary surfaces. Air delivered to the test section is controlled to close tolerances in temperature, humidity and flow rate. Steady state conditions, step changes, functional changes or real weather conditions can be simulated. Accurate measurements are taken at the inlet and outlet of the test section to determine the amount of heat and mass transfer across the system. The facility is completely computer controlled. The control software, employing a self-tuning proportional-integral control methodology, was developed in-house. A description of both the concept and facility is presented along with examples of model verification data and a brief measurement uncertainty analysis.
