摘要
搭建了动态气流个体送风装置,产生出0.005～2.5Hz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0.08Hz和大于2.1Hz;在0.5Hz和1Hz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。
Airflows with different fluctuation frequencies from 0. 005 Hz to 2.5 Hz are generated by adynamic 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 0.2Hz to 1.3 Hz at 28 ℃, 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.
