摘　　要：以空气焓值法测量房间空调器额定制冷量为例,分析了室内侧送风侧和回风侧空气含湿量、饱和水蒸气分压、比热等热物性的计算公式和额定制冷量的测量模型。通过分析额定制冷量的测量模型确定对其不确定度的各输入量,分别通过GUM法和自适应MCM法进行额定制冷量不确定度评定。经比较验证两种方法得到的结果基本一致。自适应MCM法可以极大简化额定制冷量不确定度评定过程中的求偏导数和计算各不确定度分量灵敏系数等的计算工作,同时还能保证额定制冷量不确定度的计算精度。Taking the air enthalpy method as an example to measure the rated cooling capacity of room air conditioners,this paper analyzes the calculation formulas for the air moisture content,saturated water vapor partial pressure,specific heat,and other thermal properties on the indoor supply and return sides,as well as the measurement model for the rated cooling capacity.By analyzing the measurement model of customized cooling capacity,the input of uncertainty was determined,and the uncertainty of customized cooling capacity is evaluated using GUM method and adaptive MCM method,respectively.After comparison and verification,the results obtained by the two methods are basically consistent.The adaptive MCM method can greatly simplify the calculation of partial derivatives and sensitivity coefficients for various uncertainty components in the uncertainty assessment process of rated cooling capacity,while also ensuring the calculation accuracy of rated cooling capacity uncertainty.
