Description

A climate chamber was used to study experimentally the air flow characteristics in a ventilated space with low partitions. Two types of commonly used air distribution devices were selected for the study – a ceiling diffuser and side grille systems. A total of 16 tests were performed using the two diffusers with partition heights varying up to 1.8m (5.91 ft) above floor level. From the measured results, the thermal comfort indices were assessed. A stablisation effect of air flow was found when the partition height reached 1.8m (5.91 ft). Local draught risk was located in the occupied zone. The modified Archimedes number proposed by Jackman (1990) was used to describe the indoor air flow in the absence of a workable design guide for partitioned spaces.
