There is nowhere to hide in the hot summer to cool the roof and cool the indoor temperature for a few degrees

When it comes to the three-volt season again, we don't turn on the air conditioner in the countryside and keep sweating in the house. my mother is a thrifty person who turns on for a while at lunch and dinner, and the rest of the time is to give our children a big fan. When it was all right, I was in the house thinking about how to deal with the roof to cool down. The idea at that time was that there would be a big ice cube on the roof, and I could only think about it. The price is too high, and it is not as good as to fan the air conditioner. After consulting the data, scientific agriculture will take you to sum up those wonderful ways to cool the roof.

It is well known that the transfer of heat from the roof to the house is related to three factors: the heat source (the sun), the heat transfer (the medium from the roof to the house), and the heat emission (the heat lost from the house). That is, we have summed up three ways to reduce the indoor temperature today, the first is to reduce the heat source of the roof, the second is to block the heat transfer from the roof to the house, and the third is to increase the heat emission.

Reduce the heat source of the roof. First of all, the method we think of is a common method in rural areas, covering the roof with reflective film.

This method has a variety of options, there are also many roof processing on the market, such as tin foil, aluminum film, etc., the price also varies greatly according to the different materials used, the principle is to reflect the sun back to reduce the source of heat. The second way is to add a layer of solar panels or a coating. At present, the more popular solar panel projects in rural areas can not only insulate the heat, but also generate electricity, and the inexhaustible electricity can be merged into the power grid and sold to the state. And this method works not only for bungalows, but also for sloping roofs.

The last way is to plant trees in front of the house. in rural areas, there are probably one or two trees in front of each house, but for those who do not have big trees at home, they will not be able to enjoy the shade until more than a decade later.

To block the heat transfer from the roof to the house, the first is to lay a layer of hollow brick on the roof. at present, the roof of the building uses this method more, laying hollow brick on the roof, the room is simple and convenient, the change to the house is small, and can play an effective thermal insulation effect. Second, planting melons, fruits and vegetables on the roof, loading soil in flowerpots and planting green plants such as grapes and pumpkins can block the transfer of heat to the house and harvest fruits and vegetables, killing two birds with one stone. The third is the ceiling in the house, so that there is a heat insulation space between the roof and the ceiling, which can also play a thermal insulation effect to a certain extent.

Increase heat emission from the house. Strengthening ventilation, sprinkling water in the house, increasing the loss of indoor heat, and planting green plants indoors are also effective means to reduce heat.

If you want to keep the room temperature not so high, and at the same time do not want to turn on the air conditioner, then reduce the heat source, block the heat transfer, increase the heat loss, and use the three means at the same time, it will be more natural and comfortable than the air conditioner.

The above comes from science to promote agriculture, welcome to add my attention!
