First, if you put a basin of water in the room with a fan will keep the fan cool, open the fan to evaporate the water out of the cool wind, because the water temperature is lower than room temperature, will absorb heat.
Second, indoor cooling method:
1, let the indoor ventilation, if only one-way, indoor air does not circulate, in the hot summer indoor temperature will quickly catch up with the outdoor, open the doors and Windows, let the natural wind flow in the room, to the room ventilation.
2, after the ventilation is done, pour some water on the floor, you can also use a mop with water to drag the floor again, take away the heat on the floor, you can make the room cooler.
3, draw the light curtains, block the sun, reflect the heat radiation, the same can make the room become cooler. Planting trees and flowers also has the effect of regulating the temperature, because the plants can evaporate water through the page, so as to achieve the effect of cooling. Planting grapes, morning glory, creeper and some flowers on the courtyard balcony can reduce the temperature of the attached wall by 5 ° C ~ 14 ° C, and reduce the indoor temperature by 2 ° C ~ 4 ° C.
