To solve this problem, proposes to supply outdoor air by the roof ventilators, mix it with indoor air in the higher temperature area and depress the cold air quantity by minor positive pressure control, which proves to be a desirable method in reaching a good heating effect and saving energy through practical usage in a power generating plant.
