空气焓值法测试装置不确定度的分析及应用

摘要

给出了焓值法测量空调制冷量较完整的计算模型,并系统地进行了不确定度分析计算,全面考虑了不确定度各种影响因素,尤其是引入了实验室间比对结果对不确定度的影响,并将结果应用于提高中间制冷量测量精确度的计算方法.%Calculation models for cooling capacity test with enthalpy method are introduced.According as systematic analysis of measurement uncertainty of mid-cooling capacity calculation model in enthalpy method calorimeter,on which the affect of result from interlaboratory comparison is considered,then a solution is proposed to improve the precision of mid-cooling capacity testing.
