AbstractTests were conducted in an enclosed room fitted with a mock-up workstation to determine the effect of air diffuser types and layouts on the ventilation condition of the workstation. Seven different layouts including two types of air diffusers were tested. For each air diffuser layout, tracer gas tests were conducted to measure air distribution patterns, air change efficiency, and ventilation efficiency return air duct. Additional tests were also conducted to investigate the effect of gap heights at the base of workstation partitions and the supply air rate on the air distribution pattern within the workstation and its surrounding areas. The results are presented in two papers. Part 1 presents the heights at the base of workstation partitions and airflow rates on these patterns. Part II, this paper, presents the results of air change efficiency and ventilation efficiency.
