Abstract

Device for cooling air and lowering the temperature of premises, characterised in that it includes a box 1, a water reserve 2 fed by means of a ballcock 3, and a pump 4, equipped with pipes 5, which sucks in the water reserve in order to humidify the panel or panels called wet partitions 6 which are composed of material having a high water-retention capacity and which are disposed so as to be permeable to air. During operation, a fan 7 forces the air contained at B to be loaded with water by traversing the wet partition 6. This water-laden air leaves at A. The water which evaporates on contact with the hot air contained at A creates the cooling effect which substantially lowers the temperature of the air contained at B.

Description

 The present invention relates to a device for cooling the air and making it possible to lower the temperature of professional premises or dwellings.

 Air cooling is traditionally carried out using fans blowing inside the premises, the fresh air drawn in and out.

 It is a simple renewal of air without appreciable lowering of the temperature.

 Air cooling is badly done using air conditioners, generally large consumers of energy.

 The device according to the invention makes it possible to cool the air and significantly lower the ambient temperature by consuming very little energy.

 The device according to the invention is composed of a box, fitted with a fan which forces an air flow to take charge of water by making it pass through a wet partition and which blows this air charged with water towards the place to cool.

 Water, in contact with hot air from the place to cool, creates frigories by evaporating.

 The higher the temperature of the air to be cooled, the greater the quantity of evaporated water and the greater the lowering of the temperature.

 The accompanying drawings illustrate the invention.

 Figure 1 shows in section the device according to the invention.

 Figures 2 and 3 show two variants of this device.

 The device shown in Figure 1 comprises a box (I: having dimensions varying according to the volumes to be cooled.

The base of the box serves as a water reserve (2) supplied for example by 1 solenoid valve or more simply by a float valve (3).

 A pump (4; equipped with hoses (5) sucks in the water reserve to humidify by gravity runoff a panel called a wet partition (6), composed of material with high water retention power and arranged so as to be permeable in air, located in front of a ventilator (7d.

 In operation, the fan (7, forces the air contained in B to pass through the damp partition (6: the air is charged with water and goes to A. The water evaporates on contact with the hot air contained in A creates frigories which will lower the temperature appreciably.

 The device, object of the invention, works in both directions. It is enough to reverse the direction of rotation of the fan (7) which will suck in the air contained in A to cool the air contained in B.

 The device shown seen from above in FIG. 2 is a variant of the invention where 3 of the sides of the box are made up of damp partitions (6) to increase the air / water exchange capacity and make the device more efficient.

 The upper and lower parts of the box can also be fitted with damp partitions - Fig. 3 sectional view.

 These 2 variants also work in both directions.

The device which is the subject of the invention can be controlled by an adjustable thermostat with for example 2 temperature thresholds.

 1st threshold - ventilation for simple air renewal.

 2nd threshold - starting of the pump (4) for humidification of the "wet partitions" until the desired temperature is obtained which will control the shutdown of the device.

The device according to the invention is particularly intended for lowering the air temperature in verandas, greenhouses, industrial premises and dwellings.

Claims (4)

 1) Device for cooling the air and lowering the temperature of the premises, characterized in that it comprises a box (1) - a water reserve (2) supplied by a float valve (3, - a pump (4 ,, equipped with hoses (5), sucks in the water reserve to humidify the panel or panels called wet partitions (6? composed of material with high water retention capacity and arranged so as to be permeable to air . In operation, a fan (7) forces the air contained in B to charge with water by passing through the wet partition (6). This water-laden air goes to A. The water, evaporating on contact with the hot air contained in A, creates frigories which significantly lower the temperature of the air contained in B.  2) Device according to claim 1 characterized in that it may include several wet partitions (6) - Fig. 2 and -3. A to B or B to A by simply reversing the direction of rotation of the fan.  3) Device according to any one of the preceding claims, characterized in that it functions effectively in the 2 directions  4) Device according to any one of the preceding claims characterized in that it can be controlled by thermostat.
