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。
A dynamic airflow individual blowing device was set up to generate airflow with different frequencies in the range of 0.005-2.5 Hz, and subjects were subjected to human thermal reaction voting test. The results showed that the susceptible frequency range of fluctuating airflow at 28 ℃ was 0.2 ~ 1.3Hz, the range of fluctuation sensitivity was less than 0.08Hz and greater than 2.1Hz. Under 0.5Hz and 1Hz airflow, the thermal sensation value Lower, and even reached a cool state, it can be inferred that, in the case of the same average wind speed, the fluctuations of the air flow enhances the body’s cold feeling.
