Concludes that it has lower ventilation efficiency under adverse climate conditions, that the change in opening size of doors, location of side windows and layout of roof ventilators can not improve ventilation efficiency markedly, that the ratio of the area taken by roof ventilators to that of the roof up to 45%~60% can reach satisfactory venti...
