| 摘 要： | 本文在建筑物外墙内表面温度大于室内空气露点温度的条件下，对结露问题做了实质性的讨论。利用空气温度和湿度两个参数，在焓湿图上确定了保证在建筑物外墙内表面上不出现结露的空气状态点，并在此基础上导出了不发生结露条件下外墙的最大允许传热系数计算公式。

| Abstract: | The dew condensation problems have been substantially discussed under the condition that the inside surface temperature of exterior wall is higher than that of the indoor dewpoint. The air state point, which ensures that the dew condensation does not occur on the inside surface of exterior wall, has been determined in enthalpy-moisture chart by using two parameters of indoor air temperature and relative humidity. And on this basis, the calculating formula of the maximum heat transfer coefficient of building exterior wall under the non-dewfall condition has been derived in this paper. |
