| 摘 要： | 在利用太阳能热泵供热实验台对系统的供热性能进行实验研究时,流量计因被测介质不同及长期使用会产生实验误差.为了提高测量水平,减少误差对实验的影响,本文中的实验采用重量法,分别对室内、外管路上的LZB型玻璃转子流量计和MCE08-787型累积式流量计进行了标定,并求出了各自的流量修正系数,以此来提高实验台的测量精度,从而保证实验结果的可靠性和准确性.

| Abstract: | The experimental research was conducted for the heating performance utilizing the solar - assisted heat pump experimental platform. Experimental errors will be caused to flow meter by different measured media and long time usage In order to improve measurement precision and reduce the experimental errors, this test use gravirnetric method to calibrate the LZB glass rota meter and MCE08 - 787 cumulative flow meter of indoors and outdoors pipes. The paper also presents flow correction coefficient to guarantee both the accuracy and reliability of the experimental results. |
