摘　　要：目前很多电风扇产品能够模拟自然风,但是电风扇的自然风功能处理后的风是否真正接近自然风,尚缺少统一的测试方法。研究人员经过大量的试验和研究发现湍流强度可以表征气流紊动的特点,同时自然风的脉动特性由其自身的1/f紊动特性决定。考核室内环境热舒适性的常用指标中与电风扇产品相关度较高的是吹风感指数和预计平均热感觉指数,研究了利用吹风感指数和预计平均热感觉指数进行电风扇产品自然风挡位的热舒适性测试方法,并对多个电风扇样品进行测试验证。经测试验证,满足自然风要求的电风扇产品的热舒适性明显好于不满足自然风要求的电风扇产品。At present,many electric fan products can simulate natural wind,but there is a lack of unified testing methods to determine whether the processed wind of the natural wind function of electric fans is close to natural wind.Researchers have found through extensive experiments and research that turbulence intensity can characterize the characteristics of airflow turbulence,and the pulsation characteristics of natural wind are determined by its own 1/f turbulence characteristics.The commonly used indicators for assessing the thermal comfort of indoor environments are the blowing sensation index and the expected average thermal sensation index,which are highly related to electric fan products.This study investigates the use of the blowing sensation index and the expected average thermal sensation index to test the thermal comfort of natural wind gears in electric fan products,and verifies the results through testing multiple electric fan samples.After testing and verification,the thermal comfort of electric fan products that meet the requirements of natural wind is significantly better than that of electric fan products that do not meet the requirements of natural wind.
