The main objective of this project is to experimentally characterize an air distribution system in heating mode during a period of recovery from setback. The specific air distribution system under evaluation incorporates a high sidewall supply-air register/diffuser and a near-floor wall return air grille directly below. With this arrangement, the highest temperature difference between the supply air and the room can occur during the recovery period and create a favorable condition for stratification. The experimental approach will provide realistic input data and results for verification of computational fluid dynamics modeling.
