摘要
本文分析了热量表计量热量的原理,指出利用欧洲热量表标准EN1434及国际法制计量组织的国际建议OIMLR75-1中规定的两种方法计算系统散热量的不足,根据笔者推出的供热系统流量发生阶跃变化后其过渡过程中散热器散热量与时间的函数关系,分析了在流量发生阶跃时过渡过程中热量表计量热量的误差及其变化规律,并提出了改进方法。
In this paper the principle of heat measurement is analyzed. According to EN1434 and OIML R-75, there are two methods in heat measurement, and they are all steady-state methods for test, using them in the transient after step change of flux will result in error. The error of heat measurement during the transient is obtained with the author＇s function, method is put forward. Which is presented in reference. Finally the improving
