Heat Transfer Performance of a Roof-Spray Cooling System Employing the Transfer Function Method

Abstract

Roof-spray cooling systems have been developed and implemented to reduce the heat gain through roofs so that conventional cooling systems can be reduced in size or eliminated. Currently, roof-spray systems are achieving greater effectiveness due to the availability of direct digital controls. The objective of this thesis was to develop a mathematical model of the heat transfer through a roof-spray cooled roof that predicted heat transfer based on existing weather data and roof heat transfer characteristics as described by the Transfer Function Method. The predicted results of this model were compared to the results of existing experimental data from previously conducted roof-spray cooling experiments
