在本研究中，对安装在商用空气处理机组上的标准冷冻水冷却盘管进行了能量平衡和不确定性分析，该盘管在常规PID回路控制的典型条件下运行。评估了两套不同的相对湿度变送器和温度传感器（高精度和低精度），用于测量进出冷却盘管的湿空气的相对湿度和温度。介绍了这些传感器和安装中的不同误差对能量计算不确定性的影响。此外，还评估了冷却盘管固有瞬态行为对能量平衡的影响。这项研究深入了解了如何使用能量平衡测试和不确定性分析来验证冷却盘管系统性能和仪表输出。 实验结果表明，冷却盘管固有的瞬态行为对能量平衡计算的影响可以忽略不计，通过使用高精度仪器和仔细安装，可以获得预期的能量平衡结果。单位:双引文:ASHRAE交易，第115卷，第。2、路易斯维尔2009

In this study, an energy balance and uncertainty analysis was performed on a standard chilled water cooling coil mounted in a commercial Air Handling Unit operating under typical conditions with a conventional PID loop control. Two different sets of relative humidity transmitters and temperature sensors (high and low accuracy) were evaluated for measuring relative humidity and temperature of the moist air entering and exiting a cooling coil. The impact of the different errors in these sensors and installation on the uncertainty in the energy calculation is presented. In addition, the affects of the transient behavior inherent in the cooling coil with respect to the energy balance was evaluated. This study gives insight to how an energy balance test coupled with an uncertainty analysis could be used to verify the cooling coil system performance and instrumentation output. Experimental results showed that the transient behavior inherent to the cooling coil had a negligible affect on the energy balance calculations and that by employing high accuracy instrumentation and careful installation, expected energy balance results could be attained.Units: Dual
