Definitions

  • the present invention relates to an air generator with controlled temperature, especially for livestock buildings or industrial, this generator consisting of a box housing at least one burner and at least one fan dilution to propel in a room, at temperature desired, the air circulating in said box.
  • These generators are today generally exclusively used as heating device. They usually have a only source of air supply constituted either by outside air or fresh air, either from local air or recycled air.
  • the use of air room allows a reduction in energy consumption, especially in winter because it is cheaper to heat air close to room temperature than air outdoor temperature dependent on conditions climate.
  • the air used is air of the room, the generator is generally placed at inside the building. This results in risks fire.
  • the composition of this air requires a parallel installation of significant ventilation.
  • the burners used in this type of generator are usually burners atmospheres whose power range is reduced.
  • the generator operation is discontinuous in this case and consists of a succession of judgments and implementations walking requiring increased monitoring and increasing energy consumption.
  • the generator supply air is constituted by the outside air
  • consumption energy is important and humidity problems can arise especially in winter when the air is more dry.
  • this generator can, in certain conditions, partially meet the requirements of ventilation.
  • the temperature controlled air generator has a recycled air inlet shown in (80) in the figures, closable by means of obturating members represented in (84) and (90), an external air inlet shown in (62), closable by means of shutter members shown in (86) and (90) and an external air inlet shown in (76) for the supply of fresh air to the burner.
  • the cooperation of air inlet shutters (80) and (62) makes it possible to obtain, inside the box, a flow air consisting of a mixture of fresh air flow and flow recycled.
  • each air inlet is closed by means of a sealing member which is attached thereto clean
  • these shutter members can be controlled by synchronous operation to allow opening of an air inlet parallel to the closure of another air inlet.
  • the very arrangement of the air inlets means that to this particular conception of the shutter members. It is the same in the generator described in the patent US Patent 5,290,188. Indeed, this generator comprises at the level from the box an external air inlet shown in (53) and closable by means of closing members, an outside air inlet (40) intended to supply the burner and a recirculated air inlet (69) closed by means a shutter member (67).
  • An object of the present invention is to provide a temperature controlled air generator whose design simplified allows reduced energy consumption while by authorizing one use of this generator at a time as a heating and ventilation device.
  • Another object of the present invention is to provide a temperature controlled air generator whose design makes it possible to comply as much as possible with the heating instructions and ventilation of the room.
  • the invention relates to an air generator with temperature controlled especially for livestock building or industrial, this generator consisting of a box housing at least one burner and at least one fan dilution to propel in a room, at temperature desired, the air circulating in said box, this generator comprising at least two sources of air supply, one of recycled air drawn from the room to be heated, the other fresh air from outside the room, the generator also includes a mixer controllable airflow to obtain a flow in the box fresh air or a recirculated air stream or a mixture of air fresh and recycled air depending on variations in climatic conditions and / or ventilation needs of occupants of the room, this mixer tap consists of a shutter mobile located at the confluence of the supply veins in recirculated and fresh air to regulate the flow said air supply sources.
  • the temperature-controlled air generator shown under the general reference 1, object of the invention, is more particularly intended to be used in the context livestock buildings or industrial buildings.
  • This air generator can be placed indifferently to outside or inside the room to be heated.
  • This generator 1 is constituted, in a manner known per se, a box 2, generally metallic, housing at least a gas burner 3 and at least one fan 4 of dilution.
  • This dilution fan 4 arranged upstream or downstream of the burner 3, is intended to propel, by suction or blowing, the air circulating in said box in a room at a desired temperature.
  • box 2 is equipped with a hot air outlet shown at 9 in the figures.
  • the air generator conventionally comprises at least one air inlet.
  • the flow of the dilution fan is chosen depending on the volume of the room to be heated to allow heating of the entire room volume.
  • the generator 1 has at least two sources of air supply, one, shown in 5 in the figures, of recycled air drawn in the room to be heated, the other, shown in 6 aux figures, fresh air from outside the room.
  • the fresh air inlet 6 thus consists of an opening formed in the bottom wall or in a side wall of the generator housing positioned outside the building, while the inlet 5 for recycled air is formed by a tube connected to a side wall of the generator of such so that the bottom wall of the tube is arranged coplanar at the bottom wall of the housing and that the end of the tube opens directly above the opening defining the entrance 6 fresh air.
  • This generator 1 also includes a ventilation mixer 7 controllable to obtain an air flow in box 2 fresh air or a recirculated air stream or a mixture of fresh air and air recycled according to variations in conditions and / or occupants' ventilation needs from the local. So, thanks to such a generator, it is possible obtain 0 to 100% fresh air flow or 0 to 100% recirculated air flow or a mixture of fresh air and air recycled in any proportions determined by operator based on parameters chosen by this last, especially depending on weather conditions and / or the ventilation needs of the occupants of the premises.
  • this mixer tap consists of a single movable flap 7 arranged at the confluence of the recycled air supply streams and in fresh air to regulate the flow of said sources 5, 6 air supply.
  • the flap 7 is thus arranged at the intersection of inputs 5, 6 delimiting in the housing of the generator of the perpendicular opening planes between them.
  • the plans for opening the inputs 5, 6 in the housing of the generator thus form a dihedral, the flap 7, of preferably housed inside the volume of the dihedral, being hingedly connected to the dihedral edge, this edge constituting the pivot axis of the flap 7.
  • the pivot axis of flap 7 is horizontal.
  • This component 7 can be moved manually using a pull tab 10 allowing the flap to pivot around an axis 11 of rotation, as shown in Figure 3, or else be motorized by a servomotor controlled by a PLC.
  • the arrangement of this component at the confluence of veins allows this component to be used as a obturation member unique for the two air intakes 5, 6 and to simplify its command on the move because naturally, when it closes a certain percentage entry, it opens the other entry in the same percentage at the same time.
  • the temperature controlled air generator can both perform the functions of a heater and fan while maintaining energy consumption at a reasonable level consistent with that of a generator of air used exclusively as a heating device.
  • the burner 3, housed in the box of the generator may be of the gas induction by air type.
  • This type of burner makes it possible in particular to obtain a range of extended heating power setting.
  • this heating power adjustment range includes values can vary from 1 to 10 while the burners classical atmospheres have a power of heaters can vary within a range of 1 to 3.
  • these air induction type burners are safer because they don't require a power supply in pressurized gas.
  • the gas is introduced into the air in function of the air flow, this air flow being obtained at by means of a fan supplied with primary air generally corresponding to outside air.
  • combustion obtained by means of this type of burner is of better quality, in particular in terms of quantity of nitrogen and carbon oxides products.
  • This type of burner can also be used with a combustion support, also called flame catcher, of the type consisting of a set of fibers metal formed from an iron-chromium-aluminum alloy supplemented with at least one rare earth such as yttrium.
  • a combustion support also called flame catcher
  • a combustion support of the type constituted by metallic fibers allows to increase so considerable range of power adjustment heated. This gives a heating power which can vary from 1 to 10 and not more than 1 to 3 as in the state of the technique. This results in a decrease in the frequency of switching between the on and off positions of the burner. This results for the user in an absence feeling of discomfort which was due to the inertia of conventional burners.
  • each link is carried out according to a predetermined order depending on the relative positioning burners on the common gas supply line so as to allow automatic ignition of the flame of a BE slave burner by contact of the mixture air / gas expelled from said burner with the flame of a burner master BM or adjacent slave BE.
  • the shutter with controlled opening / closing of the connection between a master or slave burner and the source gas supply can affect a lot of forms. It can thus be made up of a single organ common to all burners.
  • this organ shutter is mounted in sliding sliding contact support inside the gas supply line and is axially movable inside said pipe for release and obstruct successively during its moving the connection port of a burner to the gas supply line.
  • the displacement of this the shutter member can be operated manually or by means of a driving organ.
  • This obturation member can by example consisting of a piston or a fitted drawer at least one external peripheral seal.
  • the obturation member can also be made up of a pre-calibrated closure member, such as a valve loaded by an elastic return means, the opening or respectively the closing is a function of the pressure gas prevailing inside the supply line in gas.
  • the tare weight of each sealing member is chosen depending on the relative positioning of the burner at which said organ relates.
  • the loaded shutters by an elastic return means, such as a spring, are arranged respectively inside the pipe gas supply, between the gas supply source line gas and the burner to which they relate.
