摘　　要：选取7个影响空调系统提前关机时间的因素:外墙传热系数、屋面传热系数、外窗传热系数、窗墙面积比、人员密度、设备功率密度、照明功率密度,在正交试验基础上,运用TRNSYS模拟不同工况下的空调系统提前关机时间,通过极差分析得到各因素对空调系统提前关机时间的影响程度。对试验结果进行回归分析,得出空调系统提前关机时间的多元线性回归模型,并验证该模型的准确性,结果显示预测误差在6%以内。Seven factors caused the early shutdown of air conditioning system are chosen, includingthe external wall heat transfer coefficient, roof heat transfer coefficient, external window heat transfercoefficient, window wall area ratio, personnel density, equipment power density, lighting power density.On the basis of orthogonal experiment, the early shutdown time of air conditioning systemis simulated byTRNSYS under different working conditions, and the degree of influence of various factors on the earlyshutdown time of air conditioning system is obtained by range analysis. The regression analysis of the testresults shows the multiple linear regression model of the early shutdown time of the air conditioning system.The accuracy of the model is verified and the results show that the prediction error is within 6%.
