摘要
分析了目前制冷工业生产中对毛细管进行检测的现状,指出了现有检测方法存在的缺陷,提出了一种新的方法——等效对比代换法。根据此新方法,设计了一种新的毛细管流量检测装置。同时,在研究分析的基础上,对毛细管实验方法的国家标准GB/T23683—2009提出了新的建议和补充。
The actual situation of the capillary tube test was analyzed in the air conditioning industry. Then it lays out the exist- ing deficiency in this test and proposes a new method which is called equivalent comparative substitutional method. According to this method, the authors have developed a new device in order to test the flow capacity of capillary tubes. Based on the analysis, the authors have provided several new suggestions and additions to the national standard GB/T 23683 - 2009 in the capillary tube testing methods.
