Thermal comfort and productivity with task-ambient conditioning system in office

在人工气候室内进行了不同类型的作业条件化系统对人体热舒适性和工作效率的影响的主观实验。任务调节系统包括两个非等温系统，3DU^+和PEM，以及一个等温系统，TU，单独控制。受试者首先参与“实践情境”。然后，他们参加了使用和不使用每个任务系统的条件。使用任务系统在28℃ 50%RH下调节灭菌舱，不使用任务系统在26℃50%RH下调节灭菌舱。在任务条件反射系统条件下，舒适感的平均评分介于舒适（0）和轻微不舒适（-1）之间。对于男性来说，它在-0.4和-0.7之间，女性在-0.3和-0.4之间。这相当于甚至优于无任务系统的情况。结果发现，这些系统在提供热舒适性方面是有效的。主观症状测试和视疲劳的评分在不同条件下的男性中没有差异。在PEM和TU条件下，很大比例的女性表示厌倦。由于这是一个趋势类似的结果，从前面排出空气的空调系统可能会影响眼睛，从而增加test. Subject实验与任务空调系统，RCU，进行了调查的影响，不同类型的任务空调系统对乘员的热舒适性和生产力在气候室。在28℃50%RH条件下，使用RCU系统时，受试者的舒适感优于26℃50%RH条件下未使用RCU时的舒适感。因此，可以认为RCU在提供热舒适性方面是有效的，而不增加能耗。

Subjective experiments were conducted to investigate the impact of different types of task conditioning system on occupants with regards to their thermal comfort and productivity in a climate chamber. The task conditioning systems included two non-isothermal systems, 3DU^+ and PEM, and one isothermal system, TU, with individual control. The subjects participated in ‘practice condition' at first. Then they participated in conditions with using each task systems and without using them. The chamber was conditioned at 28℃ 50%RH with using task systems, and 26℃50%RH without using them. Under the condition with the task conditioning systems, the average rating of comfort sensation was between comfortable (0) and slightly uncomfortable (-1). For males it was between -0.4 and -0.7 and for females between -0.3 and -0.4. This was equal to or even better than that in condition with no task system. It was found that these systems were effective in providing thermal comfort. The scores of subjective symptoms tests and asthenopia were not different in males between conditions. A large percentage of females declared weariness in the PEM and TU conditions. Since this is a trend similar to the result of the addition test, air conditioning systems that discharge air from the front may have affected the eyes and thus the scores of the addition test.Subjective experiments with task conditioning system, RCU, were conducted to investigate the impact of different types of task-conditioning system on occupants with regard to their thermal comfort and productivity in a climate chamber. Under the condition of 28℃50%RH with the RCU system, the subjects' comfort sensation were more than equivalent to the condition of 26℃50%RH without RCU. Therefore it could be considered that the RCU was effective in providing thermal comfort without increasing energy consumption.
