slow. It is also free of environmental pollution and easier to manage. In the well system

Selective reversal of impeller rotation inside a metal or cement well, cold air accumulation

Finds on the surface of the gardens move to the upper layers and outside the canopy of trees.

Selective reverse well system of brick type on quiet nights when there is no wind and

The sky is clear and uncloudy, the earth's heat is exaggerated by the long wavelength and due

The absence of obstacles that cause it to return to the ground leads to the cooling of the surrounding air

The ground becomes. As a result, the air near the ground is colder than the air due to heat loss

It rises above itself, so-called temperature inversion conditions have occurred. Intensity

This inversion depends on the temperature difference between the surface air and the top of the inversion layer. But

These conditions are the inversion of temperature at the level of a valley or at the level of a plain and exclusively at night.

Occurs. The gentle breeze raises the intensity of this inversion

Reduces. Because it causes the hot air above the inversion layer with the cold air below it

Combine layers. The well machine is based on different air densities at different operating temperatures

he does. The colder the air, the higher the density.
