摘　　要： 平衡环境型房间量热计是一个综合性试验设备,其测量准确度与多项因素有关,处理好每一个参数的测量误差,就可为该设备整体准确度的提高创造条件。以《GB/T7725-2004房间空调器》标准为依据,分析了室外侧隔室再处理机组冷却盘管进口水温和泄漏风量迁移能量对空调器额定制冷量测量精度的影响在此基础上提出了更为合理的测量方案,并且计算分析和试验结果表明,泄漏风量迁移能量的记入可显著提高平衡环境型房间量热计测试窗式空调器制冷量的精度。 Typical ambient calorimeter is a kind of general testing facility, Its accuracy of measurement relates to manyfactors. So to control measurement error of each parameter is essential to improve the precision of the calorimeter, The influence of the temperature of the cooling water entering the coils in air handling unit for outdoor room and the energy with the leaked air on the measurement accuracy of normal cooling capacity of room air conditioner is analyzed according to GB/T7725-2004, Several more reasonable ways to measure are put forward based on the above analysis, and the results demonstrate that the accuracy of cooling capacity of window type air conditioner can be remarkably improved by adding the energy with the leaked air when measured with the calorimeter.
