for passive cooling of your home  -  heat transfer film
Global warming is happening much earlier than ever, and at this rate we may not leave anything for our future generations.
While all of us must reduce consumption, waste, garbage generation and other measures, it is equally important to design a comfortable lifestyle that does not depend on energy and electricity.
The cavity roof is part of the solution for passive cooling, embedded in pottery tanks, hollow filled tiles, etc.
However, even hollow clay becomes less effective in extreme summer.
Heat is transmitted by conduction and convection, the former by solid material, and the latter by space and space.
When the building terrace receives direct sunlight, it is heated and begins to pass the heat down to the room below.
Even a hollow clay filling the gap inside the roof will allow the heat to pass through it, because this trapped air will also be heated as the surface heat rises.
In other words, the current hollow clay-filled roof will let the heat pass through the conduction and convection processes, and the void is sealed.
If the trapped air in the heated void is not sealed, but moves to allow the cold air to enter, then the heat transfer is reduced.
This can be achieved by inserting a small electrical conduit between the gaps embedded in the hollow clay filling block embedded in the rolling concrete roof.
Once all the blocks are in place, a small length of pipe is inserted so that their ends are inside the void of the filling block.
This is not a continuous end. to-
End tube, it has no use at all, but a short connection between the gaps.
When the air inside the void is heated, it moves along the pipe to balance the heat on the filling block.
At the Edge block, this hotter air is discharged from the block itself, while the colder air enters the void from the other end.
Between the two outer edges of the plate, one will have wind, called the windward direction, and the other end will not have too much air movement, called the leeward direction.
The air moves from the windward direction to the back wind direction, during which the hot air that accumulates in all the gaps in the filling roof is discharged.
This can reduce the heat increase in the room.
The ends are slightly bent to block the rain.
Pipe pieces should not move so much that their ends are in the gap between concrete-filled tiles, in which case the continuous air movement is blocked.
All the builder contractor has to do is have a few helpers plugged into the pipe, which is pretty fast. It’s a one-
The time input of time and energy has realized a passive cooling of a slightly higher order. (Varanashi @ gmailcom)
