相同热感觉条件下不同环境温度与风速组合对人体舒适性及工作效率的影响
Effect of different combinations of air temperature and airflow velocity on human comfort and work efficiency under the same thermal sensation environment
摘要:
在人工气候室中,利用不同的温度和风速组合营造使受试者热感觉(TSV)相同的环境,进行主观投票和模拟打字,考察相同TSV条件下不同环境温度与风速组合对人体舒适性及工作效率的影响。结果表明,在偏热的环境下,气流可以显著地改善人体的热感觉和热舒适;在TSV相同的情况下,高温、吹风的环境与低温、无风环境相比,受试者的热舒适度和对环境的可接受度差异不大,工作效率没有显著性差异。适当调高室内设定温度并辅以气流的调节,可保持人员的热感觉水平处于舒适状态,而且不会导致工作效率降低。
Abstract:
Creating the same thermal sensation environment using different combinations of air temperature and airflow velocity in a climate chamber, through the questionnaires and the tests of simulating typing work, studies the influence of different combinations of air temperature and airflow velocity on the comfort and work efficiency of the subjects. The results show that in warmer environment, airflow could improve thermal sensation and comfort significantly. When thermal sensation is the same, compared with lower temperature and still air, the thermal comfort, environmental acceptability and work efficiency of the subjects show no significant difference in an environment with higher temperature and airflow rate. It proves that a higher temperature environment with airflow is capable of maintaining acceptable comfort and good work efficiency in offices.
