摘要
根据测量误差的基本概念和原理,针对暖通空调水系统温差小、测量精度差的特点,提出了经济、有效地提高能量计量精度的具体做法。对工程实际应用中的常见问题进行了分析,指出能量计量的精度等级达到3%是比较经济可行的。
According to the basic concept and principle of measurement error, aiming at the characteristic of small temperature difference and poor measurement precision, the concrete method of enhancing the energy measurement accuracy effective and economical was pointed out. The common questions in the application of actual project were analyzed,it was pointed out that it was feasible to achieve 3 % for energy measurement accuracy.
