The Effect of Supply Air Volume on Room Temperature Stability and Uniformity



Stephen J. Treado, Natascha S. Milesi-Ferretti


The effect of supply airflow rate on the thermal conditions in a high-accuracy temperature controlled laboratory space was investigated using the NIST/BFRL Temperature Control Module. Detailed measurements were conducted of air and surface temperatures within a test room intended for use in applications requiring extremely precise control of air temperature, with a specification of +/-0.01 degree centigrade accuracy, stability and uniformity. The major independent variable in this series of experiments was the supply airflow rte. The impact of supply airflow rate on room air temperature stability and uniformity is presented.
