How to cool down the room if it is too hot

If the room is too hot, it will cause both physical and mental torture. The body will feel too hot and unwilling to do anything, even unwilling to move. The mood will become irritable and even bad-tempered. These may be due to the hot weather. Then how to cool down the room becomes the primary thing in this season. Making ice packs, turning on fans, turning on air conditioners, and sprinkling water in the room are all good ways.

1. If you have saltpeter (nitrate) or coarse salt for refrigeration at home (you can also go to a refrigeration company to buy reusable refrigerants), pour the refrigerants into a bucket or basin filled with water. The refrigerant salts will absorb heat after dissolving in water (the right ratio of water and salt can make the water freeze). When the ice melts, it will absorb heat again, thus achieving the purpose of cooling the room. These refrigeration salts are dried after use and can be reused for refrigeration after crystallization. This method is very effective, but the operation of reuse is troublesome. If it is not reused, the cost will be high, so it is not recommended.

2. In addition, in order to drive away the stuffy air in the room, you can use a fan at maximum power and blow it towards the door or window, but do not place the fan too close to the door or window. A better solution is to use an exhaust fan with a larger power and install it above a window or door. The exhaust fan can also be installed on the windowsill where people move around. When people sit in front of the windowsill, the air flow is strong.

3. One of the main reasons for the high temperature in the room in summer is sunlight. During the day, the sun shines in through the window, and everything in the room heats up and it is difficult to dissipate heat. So remember to close the windows when you go to work in the morning. It is best to install double-layer sun-proof curtains and draw them. When you come back from get off work in the afternoon, when the sun is no longer shining, open the windows for ventilation. At this time, the wind is cool and can effectively dissipate heat.

4. Buy two more basins and fill them with water and place them in the room or near the window. If the room is not well ventilated, turn on the fan and blow it towards the basin (to save electricity, turn on the fan when you are at home). If the room is paved with waterproof tiles, you can also sprinkle water directly in the room (if the water dries quickly, increase the number of sprinklers).

5. When you just come back from outside, open all the windows first and then open and close the door a few times (like a fan, fanning it a dozen times) to effectively expel the stuffy air so that it won't be too stuffy when you enter the room.
