摘要:
主要针对通风干湿表检定中对通风速度计算方法进行分析,对因不同计算方法引起检定结果的异议,分析原因,进行探讨。利用JJG204 - 80 检定规程中计算公式进行论证分析,同时,引进空气密度修正方法对通风速度进行订正。通过对比分析表明,通风干湿表检定中通风速度在订正前后对检定结果有影响,需要对检定规程中通风速度计算方法进行严格表述以免引起歧义。
关键词: 通风干湿表, 检定, 通风速度, 探讨
Abstract:
This paper mainly aims at ventilation speed calculation method in verification of ventilation psychrometer,and analyzes and discusses the causes of different verification results by using different caculation methods. By using the calculation formula of JJG204 -80 verification regulation and the introduction of air density correction method,the ventilation speed was corrected. Through the comparative analysis,the results show that ventilation speed in verification of ventilation psychrometer before and after correction had some influence on verification results. It needs to give strictly expression for ventilation speed calculating method so as to avoid ambiguity in the verification regulation.
Key words: ventilation psychrometer, verification, ventilation speed, discuss
