Definitions

  • the present invention therefore aims to create a mechanical ventilation member which increases this vortex phenomenon while maintaining the external venturi effect, without neglecting the static suction effect due to the passage of the wind at the level of the members which constitute the end of the ventilation or chimney draft duct.
  • a ventilation unit ensures the simultaneous ventilation of all the premises, the flow rate in each of them being regulated by lids controlling each circuit.
  • Such installations must operate 24 hours a day with no means of static ventilation and fouling of their turbine by the suction of vapors loaded with grease, even suppressing thermal draft.
  • the device which is the subject of the invention makes it possible to avoid these drawbacks.
  • the turbine which creates the downpour effect which makes it possible to obtain different levels of depression in the various associated sheaths can cooperate with static members of depression which allows the use of the wind to ensure a distribution of the energy necessary for the ventilation between electric energy and natural energy, automatic regulation accessories completing the distribution of ventilation between the different rooms.
  • Figure 1 is a schematic perspective view of two open blades forming part of the turbine object of the invention.
  • the device object of the invention is constituted by the open centrifugal turbine formed by the flange 4 which supports on its underside several series of open gutter-shaped vanes , such as 10,10a and 10b, the position of which relative to the spokes of the flange 4 which carries them essentially depends on the desired degree of depression.
  • Their perfectly radial position (fig. 2b) ensures, for the same number of turns of the turbine, and the same direction of rotation given by the arrow, a lower depression than that obtained by the position of FIG. 2a in which the convex face of each blade forms an acute angle with the tangent to the flange 4 at each of them, but greater than that obtained by the object position of FIG. 2c in which the convex face of each blade forms an obtuse angle with the tangent to the flange 4 at each of them, the rotation of said turbine always taking place in the direction of the convex face of said blades.
  • each blade taken in each of the series 10, 10a and 10b for example, is such that they overlap with each other according to the drawing in Figures 2.
  • the profile of the blade which was created in order to produce the best efficiency in the direction of the desired depression, ie capable of creating the most intense downstream vortex movement at the level of the upper opening of the duct fitted with the system is a portion of hyperbola 21 which has an asymptotic angle open downstream in the direction of rotation of the turbine, one of the planes of development of said asymptotic angle, less than 90 ° , being rendered integral with the flange 4, the other plane 10 of the asymptote developing downward at the bottom of the flange 4 of the turbine and extending beyond it to develop at the same inclination to the top of the upper surface of said flange to form an inclined upper blade 20.
  • the vortex turbine 4a thus constituted (FIG. 3) being placed in the cylindrical casing situated at the lower hole of the tunnel 8 and rotating in the direction of the arrow (FIG. 2), that is to say in the direction of the convex face of the blades, and cooperating with the centrifugal turbine created by the upper blades 6 contained in the same casing at the base of the tunnel 8, it can be seen that the upstream flow sucked by said upper turbine is organized, thanks to the lower turbine (4a) in a vortex current, peripheral, intense, which envelops the upper end of the conduit 2 on which the said device is placed, creating inside the latter and along its axis a veritable upward, aspirating tornado.
  • This downpour induced inside the duct 2 by the external vortex flow generated by the turbine 4a is the result of the combined effects of the upper turbine 6 which creates an upstream flow oriented towards the base of the tunnel 8 parallel to its axis, at the periphery of the conduit thanks to the screen constituted by the flange 4 and the turbine 4a which, at the exit of the tunnel 8 gives this upstream flow a vortex effect always oriented downwards, parallel to the axis of the device and enveloping the duct 2 to the point of creating the desired tornado effect in its center.
  • the result obtained essentially depends on the distance which separates, in the same tunnel 8, the turbine 4a from the upper mouth of the lower duct 2, so that the length of the tunnel 8 (shown in dotted lines in FIG. 3) can be any, apart from the pressure drops, its extension above the turbine (4a) may be necessary to ensure a constant suction of fresh fluid according to arrow 22 at the lower periphery of the dome 9 which covers the device, even when the The device is used for the evacuation of fluid at high temperature.
  • the aerodynamic effects of the device are shown in FIG.
  • this bolster (1a) is constructed of cement, which allows its rapid fixing, without special tools, to the top of any ventilation or smoke duct constructed by masonry materials, by the simple interposition of 'a mortar binder.
  • the parallel curvilinear waves 27 which form the outer wall of this frustoconical miter (1a) ensure the inflection of the air veins which surround it when it is subjected to natural winds whose direction is not horizontal, which allows to obtain at the level of the upper mouth of the miter a practically constant venturi effect for winds whose direction deviates from approximately 30 ° on either side of the horizontal.
  • venturi effect thus produced at the level of the upper mouth of the bolster (1a) is further increased by the presence at this level of the portion of cylinder 3 which has at its upper part an external sharp edge according to FIG. 6.
  • This edge can also be made up of a metal ring inserted in the mortar used to manufacture the said miter (1 a), which can also be made entirely of metal.
  • the upper extension 20 of the blades of the turbine 4a, cooperating with the tunnel 8 at the lower hearing of which they are located ensures the cooling of the motor 7 by the suction of the outside air according to the arrows 22, creating around the motor 7 an air current which then participates in the vortex effect generated by the turbine 4a.
  • the vacuum obtained in the concentric conduits 2 and 29 is such that the air flow which it causes makes it possible to simultaneously ventilate several rooms as well as extract the smoke from the heating installation which they comprise.
  • This possibility of thus constituting a central vacuum is further facilitated by the possibility which has just been described of varying the vacuum obtained in each of the conduits by the simple positioning of their mouth relative to the main turbine 4a.
  • the suction assembly constituted by the turbine 4a, driven by the motor 7 located inside the tunnel 8, and surmounting the concentric vertical conduits 2 and 29 provided with the bolster (1a), is located outside the building's roof.
  • the central duct 29 is placed in direct communication with the room which must benefit from the greatest ventilation flow, the kitchen for example, by the duct 30.
  • the heating installation at the level of which the vacuum must be lower than the previous one for avoid excess draft is connected by the sheath 31 with the peripheral duct 2 whose mouth is located at a level lower than that of the duct 29 relative to the turbine 4a, which subjects it to a lower vacuum.
  • This peripheral duct 2 can open into the hollow, generally spherical member 32 on the diametrically opposite wall which simultaneously opens the heating duct 31 as well as the ducts 33 and 34 which communicate with the sanitary rooms in which ventilation requires flow less than in the kitchen for example which remains directly connected to the central duct 29 which benefits from the highest depression.
  • the device is completed by the regulator 35 of known type installed on the duct 2 in order to prevent the depression created by simple venturi effect by the winds which sweep the miter 26 from creating an excess of depression in particular in the duct 31 of evacuation of burnt gases.
  • each of the secondary conduits 33 and 34 is provided on its route with the special regulator 36, the object of FIGS. 7 and 8.
  • Said regulator is constituted by the generally parallelepipedal trunk 37 inside which the frame 38 can move. by rotation around its horizontal upper side 40. Sufficient sealing is provided over the entire periphery of the frame 38 inside the trunk 37 so as to ensure the passage of air only inside the frame 38 which is held in a position determined by the notches 39, the base of said frame traversing at the base the circular sector 61.
  • a flexible sheet 41 of fabrics for example, the surface of which is less than the total surface of the frame 38 but greater than the vacuum of this same frame.
  • such a device can be used with double effect.
  • the trunk 37 is internally provided with two frames 38 and 45 articulated around the same upper horizontal axis 40 and between which the flexible sheet 41 is hung.
  • the motor 7 located in the tunnel 8 receives the fresh outside air sucked in by the dorsal turbine 6. And the regulator 63 placed at the entrance of the tunnel 8 prevents excess draft which could be due to the conjunction of the depression created by the static elements with that generated by the dynamic elements of the system.
  • the chamber 50 the suction opening of which is formed by the opening 2 is therefore subjected to the vacuum which prevails at this point as a result of the same vortex effect previously described.
  • This chamber distributes the depression at the level of the conduits 33 and 34 through the common regulator 36, which convey the stale or humid air from the sanitary rooms, as well as the depression applied at the level of the conduit 31 which conveys the burnt gases from the heating of the apartment.
  • the ventilation is obtained most of the time by means of the only static elements of the system, constituted by the frustoconical miter (1 a) cooperating with the ferrule 46 in FIG. 4 or with the plate 47 provided with a lower deflector in FIG. 5.
  • the device then being provided with a contact hygrostat the possible absence of wind can result in an increase in the humidity level in the evacuation pipe, which causes the automatic starting of the turbine in view of increasing the ventilation.
  • the starting of the turbine can also be obtained by means of a manual switch operated during the hours of use of the kitchen for example, as well as by a clock which ensures an operating program of the ventilation unit.
  • the turbine speed can vary either under the effect of a manual control or under the effect of an automatic control controlled by a hygrostat placed in line 29 which serves the kitchen, the ventilation of this room can be increased either manually or automatically during the hours of operation of this room, without, however, the depression being increased in the ducts serving the sanitary rooms due to the presence of the regulator 36 which controls the ducts 33 and 34, or even in the sheath 31 for evacuating the burnt gases as a result of the relative stability of the vacuum at the entrance to the peripheral mouth 2 which is practically independent of the speed of rotation of the turbine.
  • the variant shown in Figure 5 has the important advantage, thanks to the rotation of the turbine (4a) inside the volute 48, to allow the centrifugation of fatty vapors conveyed by the stale air from the kitchen through the duct 29 or the fumes from the heating which reach through the tube 31 and their condensation on the walls of the volute 48 at the level of which they condense to flow naturally through the tube 51 provided for this purpose at the base of the volute and put in communication with the sewer towards which the pressure which reigns in volute 48 pushes them.
  • the device which is the subject of the invention therefore makes it possible to avoid the asphyxiation accidents observed during the use of known ventilation plants which use a turbine of the squirrel cage type which is freely open to the atmosphere, without the addition of static upper draft member through which the evacuated fatty vapors pass.
  • the blades of the turbine in the shape of a squirrel cage quickly become clogged by the condensation of grease at their level; so that in the event of an interruption in the electrical current, these same fouled turbines oppose the natural draft of the general collector of the building to which each individual heater is connected; which causes the diffusion in the upper stages of the burnt gases coming from the lower stages.
  • Such installations are therefore forced to operate continuously causing considerable expenditure of energy, the mechanical draft thus obtained is never relayed by a static draft, which constitutes a danger in the event of a breakdown.
  • the device thus formed is completed at its passage through the roof by the sealing sleeve 52 which facilitates installation and ensures perfect sealing at this level.
  • said cuff is guided on the duct 2 (fig. 4) or 49 (fig. 5) which protrudes from the roof and its base naturally encases the lead flange 55 whose base participates in the roofing elements of the roof.
  • the upper end of the cuff 52 the length of which is adjusted on demand comes into contact with the bolster (ta) which it supports also ensuring at this level the necessary tightness.
  • Such an assembly can therefore be effectively used to constitute a central ventilation unit for all the rooms in the same apartment, including the flue, thus economically replacing the multiple ventilation and draft systems which are currently used and whose operation is expensive because generally permanent, while the centralized system currently proposed makes it possible to ensure ventilation of each room proportioned to its own variable needs according to their daily use cycle and using the electric power only in the measure that the energy of the winds in this place is not sufficient to create the desired ventilation or the thermal draft by means of the static elements that the device also includes.
  • This ventilation assembly can also be supplemented incidentally by the deflector 56 (fig. 9) placed inside the ventilated premises, close to the upper edges at the points where an unfavorable thermal bridge causes humidity.
  • Said deflector 56 constituted by a gutter open on the wall side and furnished with diffusion fins 57 receives the air coming from outside the building, under the effect of the forced ventilation created inside of it by the central ventilation, through the perforation 58 made for this purpose in the wall of the room.
  • the upper vanes 6 can occupy a more or less inclined position relative to the flange which carries them, according to the desired flow rate of the cooling flow of the motor 7.
  • the invention can be used to economically meet the standards of V.M.C. (Controlled mechanical ventilation) which must operate 24 hours a day.
  • V.M.C. Controlled mechanical ventilation
  • the whole object of the invention makes it possible to achieve a substantial saving by its possibility of alternately using the winds thanks to its static elements or the simple thermal draft as well as its mechanical elements to create the necessary vacuum. It also allows this by the better automatic distribution of the vacuum obtained between the various ventilated rooms thanks to the regulators introduced on the circuits which automatically isolate certain rooms at the right time for the benefit of others.
  • the sanitary rooms are automatically closed by the use of automatic regulators 36, thus reducing the energy consumed to the only energy necessary for the kitchen.
  • the ventilation at medium level of all the premises resumes automatically after the timed time.
