焓差试验室湿度传感器测量不确定度分析

Uncertainty Evaluation about Humidity Test Result of Humidity Sensor in Enthalpy Difference Test Room

焓差试验室通过在分割后的房间内,于封闭的空间里提供一定的温度、湿度等环境条件,主要用于对空调产品的水流量、风量、耗电量、制冷制热性能进行评估。其温湿度环境系统的稳定性和准确性与空调性能评估息息相关,需要通过计量来确定试验室系统是否满足空调测试要求。本文对焓差试验室系统中的湿度传感器计量结果的准确性进行不确定度分析,对焓差试验室湿度系统的可信赖程度评估具有参考意义。

Enthalpy difference test room, which provide environmental conditions under certain temperature and humidity, is mainly used to evaluate the performance of air-condition, including flow, air volume, power consumption, refrigeration and heating etc The stability and accuracy of environmental conditioning system direct influence the air-condition performance evaluation, so there are calibrations to determine whether the enthalpy difference test room system meets the test requirements Afterwards, uncertainty evaluation about humidity test result is shown in this paper, and it reference to evaluating the reliability of the humidity system.
