Abstract: front page image
(EN)

With the proposed evaporative air-cooling system, we can achieve the reduction of the temperature of a space by making use of the natural characteristic of water to absorb heat during its vaporization from the body with which it is in contact. It comprises large wet surfaces created with a small mass of water within a limited space due to the activation of the molecular powers of water and of other material with molecular powers relevant to the ones of water. These wet surfaces are thin cloths, made of cotton or other material with features similar to that of cotton, impregnated with water in a controlled manner so that they can be kept wet at all times. These moistened cloths (12) are placed on bodies (G2) inside which the air of the space to be cooled circulates. Thus, when a vaporization is effected from the wet surfaces into the free atmosphere, heat is absorbed by these bodies producing a “vaporization cold” inside them. Likewise, when the air of the cooled spaces circulates inside these bodies, it leaves heat on them causing in this way the temperature of the cooled space to decrease. This decreased temperature can be by many degrees lower than the temperature of the environment depending on the factors affecting the vaporization speed, among which the relative moisture of the environment where these evaporative air cooling systems operate is the principal.
