Definitions
- the invention relates to a method of cooling the ambient air by permanent and horizontal atomization of water, assisted by a forced air ventilation to cover a programmable sectoral area provided by the drive of a stepping motor.
- the object of the invention is to reconcile, in a fixed or mobile device, the advantages of existing techniques: permanently atomizing the water under pressure with a hydraulic nozzle, assisted by a forced air ventilation to increase the carried horizontally, with an adjustable sector sweep to significantly increase the extent of coverage of the area to be refreshed.
- Fig: 1 shows a purified view of the block diagram, according to a simplified and preferred version of the invention, without taking account of the electrical programming table.
- Fig: 2 shows a partial and top view of Fig: 1 of the sectoral scanning platform with the centrifugal fan and the atomization nozzle inside the chute having a reduction in its outlet section to increase the speed of pulsed air and modify it in the form of a flat jet.
- Fig: 3 shows a view of the Fig: 1 diagram with options for improving the function of the invention.
- Fig: 4 shows a diagram showing the positioning of a water atomization nozzle in the mouth of a chute.
- Fig: 5 shows in configuration the possibility of 3 water atomizing nozzles in position under a chute.
- Fig: 6 shows 12 angular sectors of 30 ° possible in the configuration with a 360 ° scan.
- the invention consists in permanently atomizing water (1) by the action of at least one hydraulic atomizing nozzle with flat jet (2), preferably in this demonstration, for example, located, for example, inside a chute (3) whose reduced section (4) accelerates its speed and modifies the circular section of the air jet (5) into a flat jet, produced by a centrifugal fan (6), for example, and intended to prolong the action of atomized water (17) at the outlet of the nozzle (2).
- Water (1) is injected into a nozzle (2), or into nozzles (2; 2bis; 2ter), for example, which can or can be either inside or outside the chute (3 ), below for example according to FIG. 5.
- the water is put under sufficient pressure to ensure good atomization, for example 70 bar, or more, with an electric hydraulic pump (7) in this example, equipped with preferably an electronic or mechanical speed controller (7bis) which makes it possible to atomize exactly the quantity of water required while maintaining the desired water pressure and thus reduce the well-known noise of the hydraulic pump ( 7) until making it practically silent.
- an electric hydraulic pump (7) in this example, equipped with preferably an electronic or mechanical speed controller (7bis) which makes it possible to atomize exactly the quantity of water required while maintaining the desired water pressure and thus reduce the well-known noise of the hydraulic pump ( 7) until making it practically silent.
- the water (1) from the urban network (8) passes through a safety shut-off valve (9) and a filter (10) which removes particles of impurity in the water and purifies it from these bacteria by adding a well-known treatment, for example ionization, then a check valve (11).
- the water (1) circulates through a second non-return valve (12), the non-return valve (11) ensuring its closing function, then a solenoid valve (13) which opens so that the water (1) arrives in the atomization nozzle (2) when the hydraulic pump (7) delivers the water under pressure.
- a flexible pipe (14) ensures the supply of water (1) while a sweeping plate (15) is set in motion by a stepping motor (16) which allows a sweeping of atomized water (17) over an angular sector (18) for example, adjustable from 0 ° to 360 ° (in Figs: 2 and 6).
- the atomization nozzle (2) is judiciously positioned (in Fig: 4) so that the atomized water jet (17), in its upper part (19) is carried away (20) by a propelled air (5) accelerated out of a narrowed mouth (4) of a chute (3).
- the positioning of the atomizing nozzle (2) can change depending on the desired effect in the configuration of the area to be cooled.
- the device can be equipped with additional functions, for better performance and more flexibility of use (Fig 3): a refillable tank or an interchangeable water cartridge (21 ), from a source for example, in which a pumping probe (22) supplying the hydraulic pump (7) is immersed in order to pump water (23) there.
- a stopcock (24) like the stopcock (9), allows to select the water supply source (1) or (23).
- Thermochemical stack allows to cool or heat the water to a temperature that can be selected, in these extremes, between minus 50 ° Centigrade and plus 80 ° Centigrade, which can open up other outlets for use with the apparatus as in greenhouses of culture or saunas which require hot humidity, examples nonlimiting. Cooling the selected water to around 1 ° to 2 ° Centigrade increases the efficiency of the device by causing a greater temperature difference between the atomized water (17) and the outside ambient air. The atomized water (17) begins to cool the air before heating to evaporate and give the desired feeling of freshness while reducing the water consumption required due to this double action.
- Fig 6 demonstrates the efficiency of sector scanning.
- the nozzle (2) on a scanning plate (15) in the rest position, covers a sectoral area (27) of 30 ° with a range of 4 meters, ie 4.19 M2 without additional natural outside wind.
- the covered area of 4.19 M2 is already greater than the 3.14 M2 covered by an atomization nozzle used alone and vertically with a maximum action diameter of 2 meters.
- the surface covered by a sectoral angle of 30 ° is multiplied by 12, that is to say a total covered surface of 50.24 M2.
- the method according to the invention is particularly intended for cooling the ambient air by permanent horizontal atomization of water, assisted by a ventilation of forced air to cover a larger sectoral area programmable provided by the drive of a motor. step by step.
