动态气流作用下的人体可感频率

摘要

Airflows with different fluctuation frequencies from 0.005 Hz to 2.5 Hz are generated by a dynamic air supply terminal. Carries out the voting experiments of human thermal response of the subjects. The results show that the fluctuation-perceptible zone of air frequency is from 0.2 Hz to 1.3 Hz at 28°C , and that without fluctuation zone is that lower than 0.08 Hz or higher than 2.1 Hz; the thermal sensation voting value of the subjects is less even reaching to a cooler state in air frequency of 0. 5 Hz and 1 Hz, therefore it can be inferred that the air fluctuation has a strengthened cooling effect on human body under the same air velocity.%搭建了动态气流个体送风装置,产生出0.005～2.5 Hz范围内不同频率的气流,对受试者进行人体热反应投票实验.结果显示,28℃下气流的波动可感频率范围为0.2～1.3Hz,无波动感范围为气流频率小于0.08 Hz和大于2.1 Hz;在0.5 Hz和1 Hz气流作用下,受试者热感觉投票值较低,甚至达到了偏凉的状态,由此可以推断,在平均风速相同的情况下,气流的波动增强了人体的冷感.
