First, read the English article below.

This will ensure that your home is suitable for window-fan cooling. Cooling your home with window fans is not recommended for homes without window screens, as insects or animals may enter through the open windows. Noises outside the home will also become louder inside with the window open, although the fan noise may mask some of this. Take a look at your home’s outside surroundings before you decide which windows to situate your fans in. Avoid setting fans to blow inward near garbage cans or parking areas, where fumes and odors may enter the home. Creating air intake near trees or flowering plants will bring pleasant smells into your home. At night, the air near the ground will be the coolest. Situate 2-3 fans in windows on the bottom floor to blow inward and pull in cool outside air. Also use window fans for daytime cooling on chilly days. In this situation, when you’re placing inward-blowing box fans, select windows that are on a shaded side of your home. If you’re using fans during the day, set 2-3 fans to blow inward from the coolest side of the home. This will typically be the side in shade or the side facing north. Fans located in windows on the top floor of your home will blow warm air outside. If you have an attic in your home, place the outward-blowing fans in attic windows and leave the attic door open. If you’re using fans during the day, position your outward-blowing box fans in windows located on the sunny side of the house. If you live in a single-story home, set up fans to blow inward on the shaded side of your home. Set the fans blowing outward in windows on the opposite side. Leave the doors inside your home open for maximum air flow.
