资源简介：
A mathematical method is presented and verified in detail with a sample case for correcting dry-bulb and wet-bulb temperature(D&WBT) allowances set in currently enacted Chinese national room air conditioner (RAC) standard. This method works based on the investigation of RAC performance test, the analysis of the weigh ratios of D&WBTs’ effect on cooling capacity (CC) and energy efficiency ratio (EER), and the determination of the D&WBTs range where both CC and EER reach the maximum increase gradient. Comparisons between the standard uncertainties of D&WBTs within the allowances with and without correction, and comparisons between the combined standard uncertainties of the measurement CC (EER) before and after correction are made in detail. The results show that, the corrected D&WBTs allowances with weigh ratio considered can noticeably improve the accuracy of measured CC and EER profiling their true values and effectively lower the uncertainties in evaluating energy efficiency of a RAC unit.
