Building cooling and ventilating method

According to the building cooling and ventilating method, cold water is added into a water leakage groove in a water leakage groove plate, and the cold water can permeate into water absorption resin through thin holes in the inner bottom face of the water leakage groove; meanwhile, a water pump is arranged, water is introduced into a fifth header pipe through a water inlet and outlet pipe, and then cold water in the fifth header pipe enters a plurality of water bags; the second exhaust fan and the first electromagnetic valve are started, air starts to flow in the fan cover at a high speed, and a large amount of water vapor enters the fourth main pipe through the fourth air outlet pipe and enters the water bags through the fourth main pipe. The method provided by the invention is low in cost, diversified in function and convenient to popularize and apply, and can solve the technical problem of stuffiness. 本发明提供一种建筑冷却通风方法，向漏水槽板中的漏水槽内加入冷水，冷水通过漏水槽内底面的细孔可以渗入到吸水树脂中；与此同时，通过设置水泵，通过进出水管向总管五中通入水，随后总管五中的冷水进入到若干的水囊袋中；启动抽
