What if the weather is hot and there is no money to buy air conditioners?

Simple cooling method: 1 Put more pots of cold water, of course, it is best to have ice cubes to absorb heat and cool down. Mop the floor several times to let the water evaporate and absorb heat. If you are an office worker, close the doors and windows and close the curtains when you go out. The curtains are thicker and better. Don't let the hot air outside convect with the room at noon, and then open the window when you get home. The room temperature at this time is several degrees lower than when the window is open. At night, especially when it is cold in the middle of the night, we should try our best to let the cold air outside come in to reduce the indoor temperature, and we can use a ventilator to force ventilation. 3. Replace the window glass with double layers, sound insulation and heat preservation, once and for all. 4. When decorating, the insulation effect of plastic steel doors and windows is much better than that of aluminum alloy. 5. Note: If the kitchen is on the sunny side and the air is discharged to the outside, it is best to supplement it with cool air on the shady side. If the kitchen is in the dark side, close the doors and windows leading to the sunny side when exhausting air, and open the air inlet window on the dark side for ventilation to avoid the hot air on the sunny side being sucked into the room to raise the temperature. If you live on the top floor, you must keep the roof warm, otherwise Leng Xia will be too hot in winter.
