Abstract:
An evaporative air-cooling system for the cooling of spaces, e.g. domiciles, offices, stores, warehouses etc., whose desirable temperature is around 24Â° C., which makes use of the vaporization of water from large wet surfaces created with a small mass of water and within a limited space into the free atmosphere, which has a system of controlled feeding of the surfaces from which the vaporization takes place with water, so that the feeding quantity of water is equal to the quantity of water vaporized, and is characterized by that it comprises a container (B1), placed at a selected level so as to feed with water as communicating vessels by means of a pipe (F1) which may have whichever length and therefore the container (B1) can be placed far from the surfaces, other groovy-shaped containers of a (G1) type, in relation to which the container (B1) is moveable and inside which the ends of cotton cloths (I1) or cloths of another material with molecular powers relevant to those of water are plunged and thus, the cloths are moistened on their whole surface due to the molecular powers of water and cotton; by that the container (B1) is connected with a flexible pipe (C1) which has a switch (E1) and which allows it to move easily upwards and downwards, and by that the level of water inside the container (B1) is constant, this being achieved either by connecting the container (B1) via the flexible pipe (C1) to another container (A1), which is closed air-tight and which is placed on a higher level than the container (B1) and constitutes the store of water, feeding the container (B1) with water at a steady level equal to that of the opening of the pipe due to the difference of pressure created inside the container (A1) or this being achieved by connecting the container (B1) via the pipe (C1) with a water network and the steady level of water inside the container (B1) being acheived with the use of a float inside the container (B1); while the moistened cloths may be placed on already existing surfaces of the spaces to be cooled, such as doors, windows, French windows etc., or on metal containers inside which the air of the spaces to be cooled circulates, and by moving the container (B1) upwards or downwards we change the level of water inside the groovy (G1) containers, increasing or reducing the absorbed quantity respectively.
