Validation of a Computer Simulation of the Cooling and Heating Performance of a Roof Pond Building Based Upon a Detailed Analysis of Measured Heat Transfer

摘要

Roof pond system heating and cooling data acquired at Trinity University's Passive Test Facility for warm, humid climates has been analyzed. This analysis has produced a set of validated algorithms which can be used to calculate: the heat dissipation from a dry surface roof pond, the heat dissipation from a flooded roof pond, heat loss or gain through the insulated panels covering the roof pond during a summer day or a winter night, the useful energy collected by a roof pond which is operating in the heating mode, and the rate of heat transfer within the roof pond building; the effect of ceiling fans on interior transfer can also be calculated. This report presents these heat transfer algorithms and documents the measurements and data analysis which are the basis for the algorithms. The measurements cover a broad range of conditions and application of the algorithms in other warm or hot US climates requires extrapolation only in the driest and hottest parts of the desert Southwest.
