Definitions

  • the different rooms of a home have needs for variable breakdown with respect to each other, and also, for the same piece, over time. This need evolves mainly in depending on the type of rooms and the occupation. Concerning the technical parts, the need for ventilation depends mainly on water vapor emissions. Regarding the main parts, bedrooms and living room, this is the number of people occupying these which determines the level of ventilation required.
  • the function of the air inlets is not only to allow an air intake, but also to distribute it to the better to ventilate mainly occupied rooms. It is therefore essential to detect small variations between an occupied room and a empty room, in order to correctly distribute the total extracted flow. This is all the more true that one works in mechanical extraction alone, enslavement in technical parts that can lead to a reduction of the total extracted flow, which must be distributed in the occupied rooms, under penalty of degrading the air quality in these rooms.
  • the object of the invention is to provide a method and a device for adjusting the opening section of a ventilation air inlet in a room, which takes into account the humidity of the outside air and the humidity air inside the room, which also depends on the presence or not of occupants in a room, to modulate the opening section of the air intake.
  • the process which it relates to consists in controlling the opening section, on the one hand and mainly, unlike the amount of water vapor contained in the room air and the amount of water vapor from the outside air, so that the opening section increases when this difference increases and, on the other hand, optionally and independent, to the amount of water vapor in the outside air.
  • This solution allows to take into account both the quantity of water in the outside air and the amount of water in local air.
  • this method consists in measuring the relative humidity contained respectively in the air of the room and in outside air, at temperatures as close as possible to one of the other and largely independent of the outside temperature.
  • the section opening of the air inlet is always the same for a difference humidity data, whatever the external climatic data.
  • the opening section increases only when the difference in amounts of water vapor increases. This law of variation of the section opening leads to the same basic opening in summer and winter, that is to say to an identical section when the quantity of water vapor in the outside air varies.
  • this method consists in enslave the opening section, on the one hand, to the difference in the amount of water vapor contained in the room air and the amount of water vapor outside air, and, on the other hand, the amount of water vapor in the air outside.
  • the section of the base opening will vary in dependent on the amount of water vapor in the outside air, even if the difference between the quantities of water vapor contained in the room air and in the outside air is zero.
  • this process consists in increase the section of the opening when the amount of water vapor the outside air increases.
  • This mode of implementation leads to a basic opening more important in summer than in winter, since, as indicated previously, the amount of water vapor in the outdoor air is more important in summer than winter.
  • this method consists to decrease the section of the opening when the amount of water vapor from the outside air increases.
  • the basic opening is lower in summer than in winter, insofar as the cross-section of the inlet opening decreases when the amount of water vapor in the outside air increases.
  • This last mode of implementation may be advantageous in the case where the quantity of water vapor from the outside air is very important, and where you want isolate the room from outside air when the humidity increases and that the room is not occupied.
  • a device for implementing this method comprises two enclosures in communication respectively with the outside air and with the air inside the room.
  • the speakers can be located in the room to be ventilated, and designed in such a way that the intakes calories from the walls are much higher than those from the air.
  • the enclosures are separated from each other by an exchanger water vapor tight thermal ensuring final balancing of their respective temperatures, the two enclosures containing two beams of fibers sensitive to relative humidity and kept in tension by a spring, and being connected by a drive mechanism to at least one adjustment flap for the section of the air inlet opening, the mechanism drive or adjustment flaps being controlled, on the one hand, by the relative movement of the two beams and, on the other hand, by their overall movement.
  • one end of each bundle is fixed, while its other end is mounted, outside of the enclosure containing the bundle of fibers in question, on a part in form of beam which, resting on an axis disposed at the end of the exchanger and vis-à-vis which it can pivot, is directly connected or indirectly to at least one opening section adjustment flap air inlet.
  • the two bundles of fibers for example of textile fibers, have the ability to lie down when the humidity increases and to shorten when humidity decreases.
  • the two beams lengthen or shorten by the same value.
  • the difference humidity between the inside of the room and the outside, and, on the other hand, external humidity, on the flail-shaped part and on the support are fixed respectively the ends of two cables whose other ends are fixed on two flaps mounted in the opening air intake, articulated around the same axis in order to be able, in a position, be pressed against each other, one of the flaps being full, and the other comprising at least one central opening capable of being more or less closed by the first part.
  • the two shutters are plated one against the other, and the basic opening is delimited between these two flaps and the inner wall of the duct.
  • the full flap switches relative to the perforated flap, thus opening an additional passage inside this second flap to increase the air passage section.
  • the part in flail shape is integral with a lever acting on a mixing valve of two different air pressures, the pressure of the mixture being collected inside a deformable pocket acting on a flap mounted in the air inlet opening.
  • the pressures inside and outside the are different, and are used to supply the valve mixer.
  • the mixing valve comprises a piston on one end of which bears the lever fixed on the workpiece flail-shaped, the piston having a transverse opening for carry out the adjustable communication, depending on its axial position, of two chambers at different pressures with one chamber under pressure mixture.
  • FIG. 1 represents a first device, in which the air inlet opening in a room is designated by the reference 2.
  • This device comprises two speakers Vi and Ve, of which that Vi is connected by a duct 3 with the interior of the room to be ventilated, and of which that Ve is connected by a conduit 4 outside the premises.
  • These two speakers Vi and Ve are parallel, and separated from each other by a heat exchanger 5 so that the temperatures in the two enclosures are the closest possible from each other.
  • This heat exchanger 5 is mounted sliding through the support 6 located near one of the ends enclosures, and kept pushed towards the other end of the enclosures, which it also crosses, by a spring 7.
  • the flap 15 is articulated around an axis 17 transverse to the axis of the opening 2, and has a central opening 18.
  • the flap 16 is articulated around the same axis 17, and is able to pivot relative to the flap 15 to either come to press against it, or form an angle with it and more or less clear the central opening 18.
  • the flap 15 defines the base opening designated by the reference 19 while the flap 16, in combination with the opening 18 of the flap 15, defines the section additional air passage, when there is a difference between the quantities of water vapor contained in the indoor air in the room and in outside air.
  • the beams Fi and Fe have the same length, as shown in figure 2, the only possible movement being a translation parallel to the heat exchanger 5, during a humidity variation, of the same value for outdoor air and for air interior.
  • the base opening 19 then varies as a function of this variation humidity. If, on the contrary, the quantity of water vapor inside the local is increasing, that is, there is a difference with the amount of water vapor in the outside air, the beam Fi becomes longer than the beam Fe, which results, as shown in Figure 1, by a imbalance and a rotation of the beam 8 around the axis 9.
  • This rotation is materializes by a pivoting of the flap 16, which releases more or less the opening 18 of the flap 15, thus creating an additional air passage through compared to basic opening 19.
  • the beam Fi retracts, and its length becomes equal again to that of the Fe beam, which results in a movement relative pivoting of the flap 16 with respect to the flap 15, until it comes to bear one against this flap 15, when there is no longer any difference between the quantities of water vapor in the room respectively and outside.
  • FIG 3 shows another device, in which the same elements are designated by the same references as previously.
  • the operation of the fiber bundles Fi and Fe is the same than in the previous case, with pivoting of the flail 8 when there is a imbalance between the quantities of water vapor inside the room and at outside.
  • This second device aims to ensure a different treatment of the information received by the plague 8.
  • the plague is integral with a lever 22, the free end of which bears against the head of a piston 23 slidably mounted inside a cylinder 24, and which is subjected to the action of a spring 25 now this piston head pressed against the lever 22.
  • a spring 25 now this piston head pressed against the lever 22.
  • In one wall of the cylinder 24 are formed two orifices 26 and 27 parallel to each other, and in the opposite wall two holes correspondents 28 and 29 respectively opening into a mixture 30.
  • an air duct 32 is used, in which there is a positive pressure relative to the room to be ventilated, around 10 to 40 Pa.
  • a pressure P + in the upstream part of the air supply duct, and a pressure P- downstream thereof, which can be either the pressure of the room to be ventilated, or a negative pressure obtained by via a Venturi effect device, placed between the conduit 32 and the room to ventilate.
  • the orifices 26 and 27 of the cylinder 24 are supplied by the pressure P + and the pressure P- respectively.
  • An opening transverse 33 is formed in the piston 23, to allow passage air respectively from the orifices 26 and 27 towards the mixing chamber 30.
  • the mixing pressure Pm is injected into a flexible bag 34, located in a volume 35 in communication with the room to be ventilated.
  • the pressure P + which is injected into the bag 34
  • the flap 36 closes the air supply duct 32.
  • the pressure P- is injected into the flexible bag 34, the flap 36 is pushed back by the pressure P + prevailing upstream of the conduit 32, making a complete opening of this shutter.
  • Injection of a mixing pressure Pm intermediate allows to position the flap 36 so as to obtain the desired section adapted to the humidity difference between the air inside of the room and the air outside of it.
  • Figures 4 and 5 show a third device in which the same elements are designated by the same references as previously.
  • the two fiber bundles Fe and Fi are arranged parallel to each other in two enclosures Ve and Vi in communication with outdoor air and indoor air respectively. These two enclosures are separated by a sealed wall 5, allowing however the heat exchanges, so that the temperatures in these two speakers are as close as possible.
  • the two Fe beams and Fi are substantially parallel to the opening of a conduit 38 whose the opening can be more or less closed by a flap 46.
  • Each of the two bundles of fibers is fixed, at one of its ends, to a fixed point 39a, 39b.
  • each beam Fe, Fi is mounted on a part 43, 44.
  • the two parts 43, 44 are pivotally mounted around an axis A, common to the two parts, perpendicular to the two beams of fibers Fe, Fi, and parallel to the plane of the opening of the conduit 38.
  • the part 43 for fixing the beam Fe located in the enclosure Ve in communication with the outside air, also carries a B axis articulation of the flap 46, substantially parallel to the bundle of Fe fibers, Fi.
  • the part 44 for fixing the beam Fi carries the end a lever 47, the other end of which is mounted on the outside of the flap 46.
  • the lever 47 pushes the shutter by rotating it around the axis B and reduces the cross section.
  • a return spring 48 of the flap 46 in the closed position allows maintain a minimum opening by compensating for the pressure in the air supply duct. Similarly, it is possible to compensate for the weight of the shutter when the entry is placed in a horizontal position, for example in a ceiling.
  • FIG. 6 represents a diagram of operation of a air inlet opening equipped with the device according to the invention.
  • the abscissa axis indicates the quantity of water vapor H
  • the ordinate axis indicates the value of the opening O of the air intake.
  • This opening can vary between a minimum opening Om and a maximum opening OM.
  • the solid curve shows the overall movement, i.e. when the amount of water vapor the interior of the room is equal to the amount of water vapor outside, this which corresponds to a rotation around axis A in the last device described.
  • Phantom lines indicate the possibility of opening complementary to the flap, by rotating it around the B axis in the last device described, when the amount of water vapor inside the local is greater than the amount of water vapor in the outdoor air.
  • the invention provides a great improvement to the existing technique by providing a device for simple design to ensure ventilation of a room by keeping occupation account of it, playing on the difference between the amount of water vapor from the air inside the room, and steam of water contained in the outside air.
  • the means for detecting the amount of water vapor inside and outside the room could be different and not consist of bundles which we exploits the variation in length, but by hygrometers from another type, or that the heat exchanger between the two humidity measurement could be different without going out of the process according to the invention.
