基于不同热光环境下的人员工作效率的研究

Research on personnels’work efficiency under different thermal and light environments

为研究不同温度、照度、色温下工作效率与环境的关系,在实验小室中进行了一项实验.通过测试3种温度、3种照度、3种色温下学生的工作效率发现,在低温18℃,同一色温下随着照度升高,100与300 lx工作效率相差不大,而500 lx明显升高;同一照度下,在4000 K时工作效率最低,5700 K最高,即在低温时,高照度、高色温工作效率较高;但22,26℃下有所不同,工作效率表现为在300 lx、4000 K时最高.对比人体主观舒适度,发现人体主观舒适度最优的环境中并没有最高的工作效率.

In order to study the relationship between work efficiency and environment at different temperature,illuminance and color temperature,an experiment was carried out in an experimental chamber.Through testing the work efficiency of students at 3 temperatures,3 illuminances and 3 color temperatures,it is found that at the low temperature of 18℃,with the increase of illuminance at the same color temperature,the efficiency difference between 100 and 300 lx is not significant,whereas that of 500 lx is significantly increased.At the same illuminance,the work efficiency is the lowest at 4000 K and the highest at 5700 K.That is,at low temperature,the work efficiency at high illuminance and high color temperature is higher.However,the work efficiency is different at 22 and 26℃,and is the highest at 300 lx and 4000 K.Compared with human subjective comfort,it is found that work efficiency does not go the highest in the environment with the optimal subjective comfort.
