Résumé

The objective of this paper is to develop a mathematical model for the heat transfer through a roof-spray cooled roof based on existing weather data and roof heat transfer characteristics as described by the Transfer Function Method (TFM). The predicted results of this model are compared to the results of existing experimental data from previously conducted roof-spray cooling experiments. The Transfer Function Method is used to relate the energy balances at exterior and interior surfaces of the roof construction which differ in amplitude and phase due to the thermal resistance and thermal capacitance characteristics of the roof. The calculation method shows promise as a relativley simple means of predicting heat gains based on calculation procedures that are similar to those frequently used by practicing engineers.
