【摘要】 一切测量结果都具有不确定度及误差。本文通过对太阳辐射得热量测试台进行不确定度和误差分析,得到各个参数的不确定度及测量参数对测试结果的影响程度,其中风机盘管换热量的不确定度最大,而风机盘管进出口水温对测试结果误差影响最大。分析结果表明:整个测试台95%的测试误差在7.6%以内,最大测试误差约为110 W,测试台能满足测试精度要求。更多还原

【Abstract】 All the measures have uncertainty and error.The uncertainty and error of solar heat gain test facility were analyzed in this paper,the uncertainty of each parameter and the influence degree to measuring results were gained,the uncertainty of fan-coil unit heat transfer and the influence degrees of fan-coil unit inlet and outlet water temperature to the measuring results were the biggest.The results showed that 95%of the testing error was within 7.6%,the biggest testing error was about 110 W,and the precision of the test facility met the testing requirement.更多还原
