摘要(Abstract)：
在试验测试空气 空气能量回收装置的热回收效率时,测试设备、仪器仪表的精度以及新、排风进口工况对测试结果的准确度影响很大。通过对显热效率测试的不确定度的计算与分析,得出了满足给定误差限的新风进口温度范围,并分析了仪表精度对测试结果准确度的影响。
During experimental tests of heat recovery effectiveness of air-to-air energy recovery equipment, test facility, precision of instrumentation, fresh and exhaust inlet conditions have much influence on accuracy of test results. Fresh inlet temperature range which satisfies given error limits is achieved, and the effect of instrumentation precision on accuracy of test results is analyzed by calculating and analyzing uncertainties of sensible effectiveness tests.
