The task/ambient conditioning air conditioning systems attract attention in recent years from the aspect of energy conservation. In this study, the effects of respirable air quality or local cooling on workers’ productivity were studied. We used infrared spectroscopy to measure cerebral blood flow in an effort to evaluate the mental workload. It was confirmed that the mental workload level to maintain task performance was increased in the hotter environment than in the thermally neutral condition. Theanalyses indicate that local cooling of the task fan had better impact on mental workload than simply controlling thermal sensation via room temperature. The cerebral blood flow was not able to detect the small differences of air quality that was normally experienced in daily life.

近年来，从节能的角度来看，任务/环境调节空调系统引起了人们的关注。在这项研究中，可吸入空气质量或局部冷却对工人的生产力的影响进行了研究。我们使用红外光谱测量脑血流量，以评估脑力负荷。结果表明，在高温环境下，维持任务绩效的脑力负荷水平比在热中性条件下有所增加。分析表明，局部冷却的任务风扇有更好的影响，心理负荷比简单地控制热感觉，通过室温。脑血流无法检测到日常生活中通常经历的空气质量的微小差异。
