A fundamental study of two-dimensional room ventilation flows under isothermal and non-isothermal conditions

Understanding room air distribution is essential to the design of a ventilation system and the control of room thermal and air quality conditions. To investigate the various aspects of room air distribution, a Room Ventilation Simulator was developed with several unique features: an outer room with a HVAC (Heating Ventilating and Air-Conditioning) system to simulate different weather conditions by controlling the ambient air environment around the test room; an inner test room of modular design to facilitate changing room dimensions and configurations; an independent HVAC system for the inner test room to study different air supplies; an air delivery system capable of providing air flow rate of 2 to 52 air changes per hour; a uniform floor heating system of 48 individually controllable panels to simulate internal heat loads; a computer controlled data acquisition and probe positioning system to allow automatic measurements at precisely positioned locations; and a flow visualization system to record room air flow patterns. Additionally, computer software was developed for data analyses.
