Definitions

  • the present invention relates to a ventilation system of a building comprising at least one row of boxes intended to be occupied by at least one animal.
  • the present invention applies in particular to the ventilation of a pigsty.
  • Aeration systems known for a pigsty include for example chimneys which are mounted between two contiguous boxes of the same row, and which are provided for sucking up pure air circulating under said row via a air inlet.
  • These ventilation systems also include, for example at the end of row, mechanical means coupled to an air outlet which are provided to create a depression inside the pigsty, so as to allow aspiration by said chimneys of the air admitted via said inlet.
  • a major drawback of these systems is that a fraction large part of the air flow leaving each chimney is mainly drawn in direction of said extraction means. This may result in insufficient ventilation of the pigsty at the level of the huts, therefore for the animals occupying them.
  • EP-A1-0 595 098 also discloses a breeding enclosure, the floor of which, intended to receive a litter, incorporates tubes connected to an air duct connected to a fan outside the enclosure and intended to diffusing air through the litter to create conditions for modifying the self-composting bio-reactor type litter, the enclosure being provided with an air outlet coupled to suction means designed to create an air depression inside the building.
  • the object of the present invention is to provide a ventilation system for a building comprising at least one row of boxes intended to be occupied by at at least one animal, said system comprising at least one communicating air inlet with the respective lower chimney entrances below said boxes, at less an air outlet from said building coupled to means for sucking air into each chimney being provided above said boxes, the upper outlet of each chimney being provided under a ceiling of said building, which makes it possible to remedy this disadvantage.
  • an aeration system is such that each chimney is provided with means for regulating the speed of the air drawn in at said chimney outlet at a set value, so that said value allows the ventilation of said ceiling above each chimney.
  • said regulation means include a unit intended to control means provided for varying the passage section for the air drawn into each chimney between said inlet and said chimney outlet according to at least one characteristic of the ambient air in said building, so that said air suction speed at the outlet of each chimney is maintained at said set value.
  • said means for varying the passage section in each chimney consist of a flap which is connected to an arm forming a lever for the latter, said flap and said arm being mounted integral a fixed axis relative to each chimney, said arm passing through said inlet of the corresponding chimney and being connected to the outlet of said control unit by through actuating means, said control unit being provided for control said actuating means as a function of at least one value supplied at the input of said unit, so as to rotate each flap via said arm corresponding.
  • said actuating means consist of a rod provided to actuate said or each arm in rotation on said pivot axis.

  • Each tank 7 has in its lower part an orifice 7a for the evacuation of said droppings.
  • Each orifice 7a opens into a common pipe 7b which is transverse to the lateral sides 6 of boxes 2 and 3 of said row 1.
  • This pipe 7b is provided to ensure the evacuation of the droppings coming from said orifices 7a at one end of said row 1, via appropriate mechanical means (not shown in Fig. 1a for reasons of clarity).
  • FIG. 1 There is shown in FIG. 1 has a bottom 8 below said tanks 7.
  • a pit 7 'common to said row 1 is provided under said boxes 2 and 3, for the recovery of excrement flowing by each floor 5.
  • the bottom 8 of this pit 7 ' has been shown.

  • Said ventilation system further comprises, for example at the end of each row 1, mechanical means 11a coupled to an air outlet which are provided for create an air depression inside the pigsty, so as to allow aspiration by said chimneys 11 of the air admitted by said inlet.
  • suction means 11a for example consist of at least one exhaust fan.
  • each chimney 11 is provided with means 15 provided for varying, upstream of the outlet orifice 14 from said chimney 11, the pressure of the air which is sucked in.
  • Said pressure variation means 15 consist for example of a flap which is mounted integral with an axis 16 inside the chimney 11 corresponding. Said axis 16 is fixed relative to said chimney 11.
  • a lever arm 17 is also mounted integral at one of its ends the axis 16 which is provided with each chimney 11.
  • Each arm 17 passes through the orifice inlet 13 of the corresponding chimney 11, and its other end 18 is connected to a rod 19 made up of a cable, said rod 19 being itself connected to the outlet 20 of a control unit 21.
  • the rod 19 and said control unit 21 are installed below the level of floor 5 of said row 1.
  • the control unit 21 has one or more control inputs 22 and 23 which are respectively connected to one or more probes 24 and 25 (the number two in each of the examples in Figs. 1a and 1b). Probes 24 and 25 are positioned between the surface of the floors 5 and said ceiling 4, for example above said floors 5. They are respectively provided for measuring ambient air characteristics, such as temperature and humidity, for example example.
  • the control unit 21 is designed to control via the rod 19, in function of the values supplied to its inputs 22 and 23 by at least one of said probes 24 and 25, the rotation of said end 19 of each arm 18 relative to the fixed axis 16 of the corresponding chimney 11 (see arrows A and B for the two possible directions of said rotation).
  • Each lever arm 17 is provided to pivot the flap 15 in the same way during the aforementioned rotation, through the fixed axis 16 of which said arm 18 and said flap 15 are integral, so that each flap 15 can take several positions each corresponding to a pressure determined for the air drawn into each chimney 11.
  • Said ventilation system 9 is provided, via said ventilation unit. control 21, to rotate the flap 15 so that the pressure of the air sucked in each chimney 11 at the level of the opening existing between the wall thereof and said part 15 satisfies the following condition.
  • Said ventilation system 9 is thus provided for regulating the speed of the air which is sucked out of each chimney 11.
