空气焓差法测量制冷量不确定度的理论与实验分析

摘要

The uncertainty of air-condition cooing capacity tested in psychrometric lab was analyzed based on the mathematical model of uncertainty. The contribution of each parameter was studied and the way of reducing the cooling capacity uncertainty was proposed. An evaluating method for the uncertainty concerning complicated function was presented in the paper, which makes the evaluation of uncertainty simpler and more reliable.%基于空气焓差法测量制冷量不确定度的数学模型，研究焓差法测量空调制冷量的不确定度。通过分析各参数对制冷量不确定的贡献，提出减小制冷量测量不确定度的方法。同时本文提出一种复杂函数不确定度分量评定的方法，使不确定度的评定更加方便可靠。
