摘　　要：为准确检测房间空调器的性能,基于GB 21455-2019《房间空调器能效限定值及能效等级》的性能试验方法,详细解析了房间空调器性能测试过程中容易出现的问题。结合试验,借助VB6.0计算了房间空调器的全年能源消耗效率。试验和计算结果表明:房间空调器的全年能源消耗效率受地域差域影响较大,GB 21455-2019中给定的制冷(热)发生时间并不能全面反映房间空调器在我国不同地区的实际运行全年能源消耗效率,建议按地域差异评价房间空调器的全年能源消耗效率。In order to accurately test the performance of room air conditioner, based on the performance test method of GB21455-2019,i.e., a standard Minimum Allowable Values of the Energy Efficiency and Energy Efficiency Grades for Room Air Conditioners, the problems in the performance test process of room air conditioner were described and analyzed in detail. With the help of VB6.0, the annual performance factor of room air conditioner was calculated. The results of experiment and calculation show that the annual performance factor of room air conditioners is greatly affected by the regional difference, and the cooling or heating time given in GB21455-2019 can’t fully reflect the actual annual performance factor of room air conditioners in different regions of China. It is suggested that the annual performance factor of room air conditioners should be evaluated according to regional differences.
