摘　　要：随着极端高温天气频发,人们对空调使用可靠性要求越来越高,空调配电设计需根据实际情况进行优化;分析某学校项目空调高温跳闸原因,提出在空调配电设计中应依据空调最大电流而非额定电流来选取开关电缆规格;比较主流空调品牌设备最大电流大小,引入计算电流放大系数K_(f),探讨图集中空调配电需要系数K_(x)取值优化;最后通过计算实例验证提出的空调配电优化设计方法的可行性。With the frequent occurrence of extreme hot weather,people are increasingly demanding the reliability of air conditioning.It is needed to:optimize the air conditioning power distribution design according to the reality;analyze the reasons for high temperature tripping of air conditioning in a school project,and propose that switching cable specification should be selected based on the maximum air-conditioning current rather than the rated current in the air-conditioning power distribution design;compare the size of the maximum current of mainstream air-conditioning brand equipment and introduce the calculation of the current amplification factor K_(f) to explore the figures centralized air conditioning power distribution needs coefficient K_(x) value optimization;and finally,verify the feasibility of the proposed optimal design method for air-conditioning power distribution by a computational example.
