Summary

The primary concerns in designing an air-conditioned building comprise equipping it with proper thermal comfort, noise, indoor air quality (IAQ), energy efficiency, life cycle cost and reliability. Among these, those of most prominence are thermal comfort, indoor air quality and energy efficiency. The kernel solution for these factors lies in optimized air distribution. The comfort of the occupants in a ventilated airspace and the contaminant spatial distribution are affected by the air distribution pattern. Poor distribution, insufficient ventilation, stuffiness and uncomfortable air draughts are predominantly induced by improper airflow patterns. An optimized air distribution pattern is possible only by proper selection and positioning of air terminal units. In this article, computational fluid dynamics were used as a tool to determine the optimal supply and return terminal position. Using these optimal distribution positions, an empirical relationship was derived to find the location of supply and return air terminals for any given conditions.
