摘　　要：对研制开发的家用太阳能热水器热性能测试装置的日有用得热量和平均热损因数两个参数的测量不确定度进行了分析,分析结果表明,利用该装置测得的日有用得热量的测量不确定度受总辐射表的测量精度影响较大,平均热损因数的测量不确定度受温度测量传感器的不确定度影响较大,研究结果为提高太阳能热水器热性能测试装置的测量精度指明了方向。The measurement uncertainty analysis of daily useful heat gain and average heat loss coefficient of the tank have been performed based on the test data from the solar water heater thermal performance test facility. The results show that the precision of pyranometer has dominated the measurement uncertainty of daily useful heat gain, and the temperature sensor measurement uncertainty has significant effect on the average heat loss coefficient of the tank. The work done in this paper gives the direction to improve the measure precision of solar water heater test facility.
