Definitions

  • the present invention relates to an air conditioning process designed for premises equipped with raised floors over the entire surface (mainly modern offices, whether or not partitioned) and an installation which performs the process.
  • air conditioning of offices is traditionally carried out by fixed elements which diffuse and take up the air conditioning in the atmosphere (air conditioner, central processing, fan coil, ejector convector, diffuser etc ).
  • air conditioning is carried out by reverse air conditioners, the air treated by the air conditioner is blown into the raised floor and under the electronic elements or into the atmosphere by perforated tiles, the air is taken in directly at the top of the air conditioner or by means of a suitable duct or false ceiling.
  • EP-A-0 207 718 describes an air conditioning method for offices equipped with raised floor in which the space or plenun created under the raised floor is used for the passage of air conditioning; the method comprises the steps of: blowing the air treated by an air conditioner into the plenum said through openings; diffusing the treated air into the atmosphere by means of a diffusion slab; the air intake being made through openings in the walls placed above the air conditioner.
  • Said method has the disadvantage that the air conditioning being blown into the atmosphere after passing under the floor is often loaded with dust; in addition the raised floor must be waterproof; finally the air intake being made by the walls, easily the noise of the air conditioner fan can reach the office.
  • the present invention aims to provide air conditioning "all floor” blowing and return of air conditioning without having the restrictions and disadvantages of the existing methods and described above, and offering greater modularity allowing all changes and modifications of installation without structural modifications of the basic elements.
  • the raised floor retaining its primary function which is to allow the free and easily accessible passage of all cables and other fluids.
  • the invention proposes a method according to claim 1 and an installation according to claim 2.
  • the air conditioner (A) blows the treated air at a constant temperature (for example 20 ° C) into the duct (C) and the control device (D), if the ambient temperature controlled by the thermostat (F) is too high , the flap of the device (D) will descend, by the commissioning of the engine (I), and allow the treated air to enter the room by passing through the slab (E) Figure 1-
  • the ambient air returns to the air conditioner (A) through the return slab (G) and the plenum that constitutes the raised floor, this plenum being in constant depression by the air conditioning adapter box (H), when the ambient temperature of the room will have reached the desired value (close to 20 ° C) the shutter of the device (D) will go up by the commissioning of the engine (I) and the air blown by the air conditioner will be discharged directly into the plenum and towards the recovery of the air conditioner ( Figure 2-).
  • the shutter of the device (D) can act either in all or nothing (high or low position) or proportional in the case where a high precision of the ambient temperature is sought, in the latter case, the thermostat (F) and the motor (I) will be proportional action.
  • the process can also provide cooling in summer and reheating in winter.
  • the air conditioner will then be equipped with a hot battery (hot or electric water) depending on the equipment of the air conditioner, it is also possible to treat the air humidity (humidification and dehumidification) especially if the room is for IT purposes.
  • the air conditioner is equipped with its own regulation with temperature probe (and hygrometry if necessary) on the air intake of the air conditioner.
  • each tile (distribution and recovery) will be determined according to the location of the various elements constituting the room, but can be moved at any time, each tile (standard 600x600) being interchangeable.
  • Figure 4 shows an example of layout of the different elements that make up the process (an air conditioner for 3 offices).
  • the installation is characterized by total modularity and mobility of each element.
  • the ducts (C), the diffusion slabs (E), the return slabs (G) the thermostat (F) can be moved at any time to adapt to any new configuration of the room (or rooms) to be air conditioned, the number of the elements mentioned above can be increased or decreased at any time to correspond to a new heat balance resulting from structural modification (new partitioning, displacement of work station, new electronic equipment etc.).
  • the method makes it possible to keep the raised floor its modular appearance and the use thereof for the free passage of all cables and fluids.
