提出一种求解干湿球温度在国家标准允差范围内变化的制冷量和能效比实测结果向名义工况值回归逼近的修正算法，并以制冷工况下的室内侧干湿球温度允差范围变化的房间空调器制冷量和能效比测试结果为实例进行算法修正。该算法基于制冷量和能效比实测结果，采用多元高次方程逼近求解两者的回归方程，并用贝塞尔公式验证其收敛性。运用层次分析法(Analytic hierarchy process，AHP)量化分析干湿球温度对制冷量和能效比的影响程度，进而得出在干湿球温度允差范围内制冷量和能效比的修正算法。该修正算法可对任意工况下制冷量和能效比的实测值进行修正，并以此为基础对房间空调器能效等级进行评判。修正算法能更加准确地评判房间空调器能效等级，可对现行房间空调器性能测试方法进行完善。

A correcting algorithm is provided to work out regression equations to process the experimental results of cooling capacity (CC) and energy efficiency ratio (EER) of room air conditioner(RAC) when dry-bulb and wet-bulb temperatures (D&WBTs) change in the allowances set in national standard in China. Thereby, values of CC and EER under nominal working condition can be worked out. A case of the correcting algorithm is illustrated based on the experimental results of CC and EER with indoor D&WBTs changing in the allowances under space cooling condition. Based on the experimental results, the multiple high order equation is adopted to solve the regression equations of CC and EER respectively. Bessel formula is adopted to verify the convergence. The analytic hierarchy process (AHP) is adopted to present a quantitative analysis of the D&WBTs’ influence on CC and EER;thereby, the correcting equations for CC and EER with D&WBTs changing within the allowances are obtained. Within the allowances set in the national standard, these two correcting equations can correct all experimental results of CC and EER under any working condition, based on which energy efficiency of the RAC unit can be more accurately classified. This correcting algorithm can help to evaluate the energy efficiency grade of a RAC unit more accurately, and help to optimize the currently enacted RAC performance testing methods.
