FR2723433A1 - Air conditioner for offices, hospitals and industrial buildings - Google Patents

Abstract

The air conditioner is constituted by two adjoining chambers (2,3) forming a double casing (23) between which is an insulating material. One casing (2) contains a fan (6), a fresh air intake duct (7), a return air duct (35) and a discharge duct (9). The other casing (3) contains an air cooling and filtering system comprising a water tank (17) and three air filter drawers (20,21,23). The air is induced into the fan on two routes, one from the local recovered air conduit (31) and the other through the external air intake. The pressurised air passes through the discharge duct into a convergent-divergent diffuser (14). From the diffuser the air enters the tank containing water. The filtered and cooled air is displaced along paths created by webs (27,28,4) and is expelled for final use through the duct (25).

A flange (36) on which the external air intake is installed

  by the sheath (7), a register (8) makes it possible to adjust the flow rate.

  The air flow thus impelled by the fan, booster or compressor (6) is directed by means of a sheath (9), which leads to a grid diffuser, convergent, divergent venturi or the like (14) installed in the bottom of the box (3). The compressed or compressed air coming from the sheath (9) and the diffuser (14), ends in a submerged ventilation chamber (17), the air is blown directly into the liquid (water drinkable, alone or with the addition of a neutral solution intended to increase the refrigerating power) The liquid contained in the chamber (17) constitutes the tarpaulin. The filling level is defined and maintained by means of a level controller (19) and the filling valve for additional level (11) directly connected to the water distribution level. It should be noted that in the absence of a water network near the installation, a reservoir can be designed for this purpose and be used as a buffer reserve, the filling of the chamber (17) is then carried out according to the principle of universal gravitation. The liquid and mainly the water contained in the chamber (17) are directly crossed and stirred by the air blown in by the diffuser (14), the air can be injected through very fine channels into this mass d. contact (17) The coolant is water at atmospheric pressure contained in the tank (17), it can also be

  a very dilute neutral aqueous solution.

  From a homogeneous speed of air through the orifices of the intake diffuser (14), it passes through the liquid contained in the tank (17) by the special diffuser which makes it possible to transform all or all of the potential energy part of the kinetic energy at the neck of each orifice of the

grid (15).

- 4 '-

  The speed decreases and the pressure increases. The conicity will be determined for each type of device according to the assimilable value of the material transfer angle in the direction of production of cold with recovery by dilution in the bath. The heat transfer involves the latent heat of vaporization of the water, and the heat corresponding to the excess of water vapor is recovered, by simple

  condensation on the flanges (27 - 28 - 4).

  A special partition (16) is equipped with a solid non-drilled part intended to protect the water filling orifice of the tank (17) by the network water valve (11). In the upper part, the upper part of this special partition (16) is provided with three compartments (20 - 21 - 22), each compartment is equipped with a drawer containing the elements necessary for the operation of the assembly. The drawer (20) is an activated charcoal filter which ensures high operational hygiene. This requirement relates not only to particles or dust, but to the carbon monoxide current in atmospheric air according to the multiple incomplete combustions of the urban atmosphere in general but also to any other body (formaldehyde) for example generated by the combustion of certain natural gases or gases inherent in all kinds of combustion (nitrogen oxides),

carbon dioxide or sulfur dioxide.

  The drawer (21) is a capacitive filter composed of high density minerals. The drawer (22) is a filter composed of large

  granite pebbles serving as a mass of inertia.

  Each drawer (20 - 21 - 22) is supported and separated by a

  partition pierced globally or partially.

  The influence of the air path system from its injection into the tank (17) through the water and then from the grid or orifices (15) form a path stabilizer system which directly affects adiabatic expansion. the purpose of this is to emulsify and to filter the air injected while ensuring a vaporization under medium pressure, the advantage of which is to ensure a deconcentration of the content of any carbon dioxide, by solubility of the latter in water, this phenomenon only occurs cumulatively after one

time.

  The energy transfer begins through the mass of water contained in the tank (17) generated by the flow of air injected by the diffuser (14). Air cooling is the product of recovery along the route (1) by simple condensation. The saturation mass increases until equilibrium

thermal expected.

  The corpuscular emission (24) is associated with each gram of air transporting an amount of water, proportionally related to the

  absorbency of drawers (20 - 21).

  The variation in the density of the mixture (air + micronized water) is a function of the trigger generated and directly initiated at the outlet of the drawer (20), this creates the pressure difference which lowers the temperature. the stabilizing influence of the air path system directly affects the shape of the air stream transmitted by the diffuser (14), animated in homogeneous or turbulent flow. Air expands or shrinks proportionally to the temperature component

  axial of the water contained in the tank (17).

  The pressure drop created by the drawers (20 - 21 - 22) generates a second state of expansion at the outlet of the drawer (22), in a way through the components, filters or inertia minerals contained in the drawers ( 20 - 21 - 22), the air is

  subjected to a laminar and turbulent regime.

  A dilution and expansion chamber is determined by the flange (27) the cooled air is directed towards its first outlet path, this is determined by the flanges 27-28) then it begins the second path determined by the flasks. (28 - 4). Besides the function of ensuring that the air is cooled several times, the flanges (27 - 28 - 4) play

  a role of dehumidification by elementary condensation.

  The cooled and filtered air ends up in a molecular tranquilization chamber (3) before being expelled to the outlet duct (25), a register (26) allows to precisely adjust the desired cooling rate . The condensates are returned via the profile

  specially fitted flange (10).

  Given that the device according to the invention is capable of a process for filtering hydraulic air by water (17), a valve (18) for deconcentration and evacuation of sludge allows

  the device to be operational and efficient at all times.

  This operation of deconcentrating the water contained in the tank (17), the level of which is controlled by the level detector (19), can be automated one hundred percent. The same applies to the control of the pressure difference in the air plus water mixture and the air volume

cooled.

  In the case of using the method according to the invention during the winter period, a bypass (37) allows the intake air (31) of the room mixed with fresh outside air (7) to be blown directly above the water level of the tank (17) to ensure filtration of the outlet air (1) while avoiding freezing of the water in the device. In the case of installation outside, it is possible to provide a plunging resistance in water (17) to ensure the anti-freeze function. The flanges (34 - 35 - 36) are used to connect

the sleeves on the device-

  The device according to the invention makes it possible to manage point by point, the parameters of the dilution zone comprised between the diffuser (14), the water tank (17), the branch flange

(16) and the drawers (20 - 21 - 22).

  On the box (2) there are two ventilation holes (5 -

  12) for cooling the fan or air booster (6). An outlet (13) allows evacuation of any

  condensed water likely to form in the box (2).

  The application of the present: the invention is multiple, by its character of simplicity and rationality "absence of C.F.C." or any refrigerants. Above all, the filtration of the air, before expulsion once cooled which is naturally filtered towards the sheath (25). From adjustments of pressure differences adjustable by the registers (26 -29), if these are judiciously carried out, it is then possible to set the room where the air must be treated, in slight compression, it is to say a slight pressurization at

  above normal atmospheric pressure.

  The major interest of this process is to avoid any introduction of dust or polluted air into the room where the air must be treated from the invention and favor

the evacuation of calories.

  Its application can extend from domestic use to industrial use and by extension, in larger size, to the cooling of waters, buffer lakes or rivers and streams used to balance the temperature of the reactors of nuclear power plants E.D.F. Indeed, a nuclear power plant for electricity production is limited in its production by the increase in temperature and flow of the

  fluid which ensures its cooling, in particular water.

  The process according to the present invention is entirely compatible for the most diverse applications, it is simple, rustic and inexpensive to industrialize, it requires no preventive or compulsory maintenance, it does not pollute, it cleanses and refreshes the air. atmospheric which is more and more charged with harmful particles to the environment nowadays. It can be used for wet cooling of cold rooms intended for

  conservation of food plants.

The pressure drop of the drawers (20 - 21 - 22) generates a second state of expansion at the outlet of the drawer (22). A room of

  dilution and relaxation is determined by the flange (27).

  9) Device according to any one of claims

  previous characterized in that the cooled air is directed towards its first outlet path determined by the flanges (27 - 28), then it initiates the second path determined by the flanges ('28 - 4). The flanges (27 - 28 - 4) play a role of dehumidification by condensation. The cooled and filtered air ends up in a molecular tranquilization chamber (3) before being expelled to the outlet sheath (25). A register 26 allows to precisely adjust the desired cooling rate. The return of the condensate takes place via the special profile of the flange (10), a valve for delconcentration and evacuation of the sludge (18) from the water contained in the tank (17), the

  level is controlled by the detector (19). Two holes (5 -

  12) for cooling the fan or air blower.

  ) Device according to one of claims 2 or 9 or

  any one of the preceding claims is characterized

  in that it is allowed to manage point by point the parameters of the dilution zone. During the winter period a bipass (37) allows the intake air (31) of the room mixed with fresh outside air (7) to be blown directly, above the water level, to ensure filtration of the water. outlet air (1). Once cooled and naturally filtered, the air is expelled to the duct (25). From the adjustable pressure difference settings (26 - 29), it is then possible to set the room where the air must be treated, in slight compression above normal atmospheric pressure to avoid the introduction of dust or d air read in the room and encourage

the evacuation of calories.
