在设计火电厂主厂房自然通风开窗面积时 ,应以能够满足主厂房内卫生及工艺规范和能将主厂房内的余热量排出去为前提 ,使自然通风开窗面积达到最小。计算进排风总开窗面积是一项既繁琐又单调、重复的工作 ,有必要利用计算机辅助设计 ,以提高工作效率 In the design of thermal power plant main building natural ventilation window area, should be able to meet the main plant health and process specifications and can be the main plant waste heat discharged as a precondition to make the natural ventilation window area to a minimum. Calculating the total exhaust area into the wind is a cumbersome and monotonous, repetitive work, it is necessary to use computer-aided design to improve work efficiency
