摘　　要：在不同的气压条件下(常压、低气压)开展某热风机的风速测试实验研究。经试验验证及数据分析,在常温低气压条件下使用小叶轮式风速仪进行低风速条件下的风速测量,获得的实验结果更加真实、有效,为其他热风机产品在低风速条件下的风速测试研究提供一定的测试经验。Based on the method and principle of wind speed measurement,the wind speed measurement experiment of a hot air blower was carried out under different atmospheric pressure(atmospheric pressure and low atmospheric pressure).It is proved by experiment and data analysis that the experiment result is more real and effective by using the small impeller anemometer to measure the wind speed under the condition of low wind speed at normal temperature and low pressure.At the same time,this paper provides some test experience for other hot air fan products under the condition of low wind speed.
