Definitions

  • the invention relates to air treatment equipment. More specifically, the invention relates to air handling units in particular intended for installation in non-residential buildings, such as office buildings, industrial buildings, airports, hospitals ...
  • modules are grouped together in an enclosure consisting of one or several caissons formed of double skin walls.
  • the enclosure is sealed, with the exception of heard from the air intake and the air outlet.
  • a first disadvantage of the prior art concerns general ergonomics air handling units. Specifically, these power plants many organs, conduits, cables, control and control devices which are scattered inside and outside the enclosure.
  • heat exchangers are traditionally of the type liquid / air and therefore implement collectors presenting at a from their ends means for connection to liquid conduits (usually water)
  • collectors extend towards a side wall of the module of heat exchange so that the connection means are projecting from the wall in question.
  • connection means and / or the collectors
  • connection means at the end of the collectors make obstacle to the release of the side wall of the module, and it is therefore necessary to proceed, in order to be able to deposit the wall in question, to a disassembly connecting means, and possibly sealing means, all the collectors (by separating them from the heat exchangers).
  • a tray is provided in the lower part of the exchange module thermal.
  • the purpose of the invention is therefore in particular to overcome the disadvantages of the prior art.
  • the invention aims to propose a central air treatment that allows for improved presentation and organization of its enclosure compared to the solutions of the prior art.
  • the invention also aims to provide such air handling unit which facilitates maintenance operations and / or maintenance.
  • the invention also aims to provide such a power plant air treatment that allows easy and fast access to some of these organs internal, or even the bulk of the volume delimited by the enclosure.
  • Another object of the invention is to provide such a central unit inexpensive to manufacture, assemble and install.
  • Yet another object of the invention is to provide such a central which is simple in design and easy to implement.
  • an air handling unit of the type comprising at least one air intake, at least one first compartment integrating liquid-air heat exchanger means connected to collector means having connection means, and means for repression of the air.
  • the air handling unit comprises at least one clearance space surmounting at least said second compartment, said collector means extending from said first compartment at least partially in said clearance space so grouping said connection means at a side façade said clearance space.
  • the entire height of the plant extending under the clearance space is released from the collectors and / or means of connection that traditionally cross the walls in the vicinity of heat exchangers.
  • This aspect offers multiple possibilities in terms of presentation and organization of the power plant enclosure, as will become clear thereafter.
  • the clearance space according to the invention can be set to profit to circulate not only the collectors of the heat exchangers but also allows the positioning of any pressure taps, the placement of certain electrical equipment and electrical cables associates; etc.
  • the invention retains the possibility of stacking power plants on each other (which is common enough to win the place on the ground).
  • the air handling unit is equipped with at least one removable side wall extending under said space of clearance and likely to allow access at least within a first compartment incorporating said heat exchangers.
  • the air handling unit is equipped with at least one movable side panel extending under said space of clearance, said panel or panels being movable between a position opening, allowing access to at least the interior of said first compartment, and a closed position.
  • Such mobile panels are particularly practical to use and allow easy and fast interventions inside the enclosure of the Central.
  • the air handling unit comprises at least one air intake compartment and / or at least one compartment of air discharge, said one or more removable walls or said one or more movable panels being provided to also allow access to the interior of said air intake compartment and / or within said compartment of air backflow.
  • the organization of the enclosure of the central processing unit is preferably provided so that the collectors and / or their means of connected on the same side as the side panel (s) or the removable wall or walls.
  • said panel or panels are swivel.
  • said panel or panels are sliding.
  • sliding panels allow opening in all circumstances, including connection pipes, cabinets electric or other extending in front of the sliding panel or panels.
  • said panel or panels are movable between a plane of closure and a sliding plane.
  • said one or more sliding panels have cut-away edges for cooperating with cut-away edges another panel and / or an opening frame.
  • said cut-away edges of said one or more panels and / or said cut-away edges said frame preferably carry sealing means.
  • the enclosure of the plant thus has a satisfactory seal, thanks to the presence of the cut-away edges which optimize the tightening, and therefore the effectiveness, sealing means.
  • the central processing unit It has an extractable condensate recovery tray that can form in the vicinity of said heat exchangers.
  • said extractable tray preferably has at least a mouthpiece intended to be fitted with an evacuation duct of said condensates.
  • the space saving obtained in the lower part allows to further incline the tank, which promotes the flow and evacuation of condensates.
  • said clearance zone has at least one removable wall.
  • said clearance space carries a slide of guiding the sliding of said panel or panels.
  • the principle of the invention lies in providing, in the upper part of an air handling unit, a zone of clearance by a side wall of which is presented, in a grouped way, the means for connecting the collectors of the heat exchangers.
  • FIG. 1 shows an air handling unit 1 surmounted by a clearance zone 2 by a lateral facade 21 of which manifolds 3 (and their connecting means 31 to water pipes).
  • collectors 3 are present; indeed, we provides two heat exchangers that are each connected to a collector feeding and a return water collector.
  • the clearance zone extends over the whole length of the central processing unit and can therefore control and / or control for each of the modules of the plant.
  • the entire facade of the plant extending under the clearance zone is devoid of particular organs or accessories.
  • doors 4 are provided to allow access all over the length of the internal volume of the air handling unit. So we can easily access the air intake compartment 15 and the compartment of air discharge, respectively upstream and downstream of the compartment incorporating heat exchangers 10.
  • connection means 31 of the collectors 3 are grouped over a width of the corresponding clearing area 2 substantially the width of a compartment in which are placed the heat exchangers (shown schematically in dotted lines) of the Central.
  • doors are sliding doors.
  • the doors 4 are removable panels.
  • the doors could be pivotally mounted on the power plant frame.
  • the doors are movably mounted between a sliding plane and a closing plane, according to the illustrated variant in Figure 2.
  • edges 41 of the doors 4 have cut sides intended for form a support plane with the cutaway of an edge of a neighboring door or with the cutaway of an edge 111 of the frame 11 of the opening of the plant.
  • each of these doors comes to fit into a frame formed on the one hand by the cut edges of a door and on the other hand by the panels cut off from the frame of the opening.
  • FIG. 5 shows in more detail the output of a collector 3 at through the clearance zone 3.
  • this clearance zone includes a banner longitudinal 22 (of the length of the air handling unit) having a orifice 221 for each manifold outlet 3, the face 21 of the strip 22 being provided, at each outlet manifold, a shutter 23 cleanliness made of a flexible material.
  • the sealing of the strip 22 is ensured by a plate elastomer 24 glued to the sheet of the strip.
  • the strip 22 is removably attached using any appropriate means.
  • the strip 22 carries a sheet metal 25 forming a slide for the upper edge of the doors 4. This sheet also forms a stop intended for limit the movement of the door from its closed position to the position of sliding.
  • the doors 4 carry skates intended to roll (or slide) on a path 121 of a lower slideway 12 (can be formed in one piece with a support spar 13 of the Central).
  • the slide 12 also has a flange 122 intended to limit moving the door from its closed position to its position of sliding.
  • a locking of the doors 4 in the closed position is achieved using latches 43 "quarter-turn" which are provided to hold the door 4 against the framing of the opening by maintaining tight sealing means related to the periphery of the doors (and / or the frame of the opening).
  • the central processing unit air includes a tray 5 condensate recovery.
  • This tray 5 has a mouth 51 intended to be inserted into a conduit 52 for condensate evacuation.
  • the tray is easily extractable: once the corresponding door slid, it is sufficient to unmount the tray 5 of the conduit 52 and remove it. His replacement is also done simply by proceeding inversely.
  • the clearance space has a height of about 150 mm, the walls of the enclosure having a thickness of about 50 mm.
