Résumé

This paper outlines the methodology used to represent and verify a simplified engineering model of a VAV system with fan powered terminal units serving a three zone building. The building loads were generated for five weather diverse locations in the United States and normalized for peak and zone conditions. Experimental results from a previous study were used to build models of the individual fan powered terminal units. The resulting system model was verified against results from an experimental test stand. A test stand was configured to allow simultaneous testing of up to three manufacturer's fan powered terminal units. Typical 8 inch (200 mm) and 12 inch (300 mm) terminal units were evaluated. Results from the test stand verified the model predicted values. The predicted results were well within experimental measurement uncertainty. The verified model provides the engineering community with a tool to expand existing VAV system simulation and energy analysis capabilities (see also this Bulletin, reference 2009-2465).
