Definitions

  • the present invention relates to a diffuser for air conditioning installations, the purpose of which is to supply air to the space to be air-conditioned, such that the diffuser is concealed in a ceiling or wall.
  • Diffusers are commonly used in air conditioning installations for the purpose of orienting the air outlet in a suitable manner.
  • These diffusers usually comprise a flat strip which moves horizontally to establish the different winter/summer configurations and which, along with the outer profiles, directs the air.
  • diffusers are conventionally assembled by means of two outer profiles put together by means of different permanent mechanical connection systems (for example, riveting, connection tubes, screwing, etc.) which require the use of tools, or by means of a sliding part that is embedded in the profile at one end and retains the deflector element.
  • permanent mechanical connection systems for example, riveting, connection tubes, screwing, etc.
  • an objective of the present invention is to provide a diffuser with a tool-free factory assembly system and a system for directing air with a three-dimensional strip combining transverse movement with vertical position adjustment to obtain a better acoustic and aerodynamic behavior, which allows a larger flow to be driven.
  • the diffuser for air conditioning installations comprises a pair of outer profiles and an inner strip located between both outer profiles by means of at least one fixing bridge, where said inner strip can be located in a first position and a second position with respect to the fixing bridge, and is characterized in that in said second position, the inner strip is vertically and horizontally moved with respect to said first position.
  • the strip allows better airflow cooperation, allowing the closure of the air channel in one of the positions to prevent the generation of vortices which compromise the acoustic characteristic, and the opening of the air channel in the other position to balance out the head loss in both positions.
  • said inner strip or said fixing bridge comprises projections which are housed in the first position inside complementary housings of the fixing bridge or the inner strip and located in the second position outside said housings.
  • said inner strip is fixed to the fixing bridge by means of a fixing element, said fixing element being horizontally movable in said fixing bridge.
  • the side walls of the inner profile are preferably curved, and/or the inner walls of the outer profiles are curved.
  • the curvature of the outer walls of the inner profile has a radius greater than the curvature of the inner walls of the outer profiles, defining two contacting edges at the operating height of the second position.
  • the inner strip in said first position is centered horizontally with respect to the outer profiles, and in said second position the inner strip is moved towards an outer profile, with two edges in contact with the side wall of said outer profile, although it may also be possible that only one of the edges is in contact with the side wall of said outer profile.
  • the inner strip is vertically farther away from the fixing bridge than in the first position.
  • the fixing bridge is made of a plastic material; however, it could also be made of any suitable material which allows it to be assembled on and disassembled from the two outer profiles without any tools, which speeds up and simplifies the assembly of said profiles as no tools are required for that purpose.
  • the assembly of the bridge does not require making holes in the outer part of the profiles, which assures diffuser tightness.
  • the diffuser according to the present invention is designed to be assembled in a ceiling in air conditioning installations and comprises a pair of outer profiles 1 having a desired length, and for the sake of simplicity only a part of the profiles is shown in Figure 1 .
  • an inner strip 2 which is used as an aerodynamic strip, the position of which determines the orientation of the air outlet of an air conditioning installation, as will be explained below.
  • the inner strip 2 is fixed to the outer profiles 1 by means of one or more fixing bridges 3.
  • the or each fixing bridge 3 which is preferably made of plastic, is laterally coupled on the outer profiles 1, and a fixing element 5, for example, a screw provided with a nut 4, is used to fix the inner strip 2 to the fixing bridge 3.
  • Figures 2 and 3 show the inner strip 2 in first and second positions. Furthermore, it can be seen in these views that the side walls 21 of the inner strip 2 are curved, and the inner walls 11 of the outer profiles 1 are also curved, so as to favor air conduction.
  • the first position corresponds to the winter position, and in this first position the inner strip 2 is located in a position centered horizontally with respect to the outer profiles 1, the air coming out through the two sides thereof, as depicted by means of the corresponding arrows.
  • projections 6 of the inner strip 2 which are located on its upper face in its usage position are located inside the complementary housings 7 of the fixing bridge 3. As can be seen, these housings 7 are located in the lower part of the fixing bridge 3 in its usage position.
  • said projections 6 may be located in the fixing bridge 3, and in this case, the housings 7 would be located in the inner strip 2, with the projections 6 and housings 7 performing the same function.
  • the second position corresponds to the summer position, and in this second position the inner strip 2 is moved horizontally to be substantially in contact with the inner wall 11 of the outer profile 1.
  • the air therefore comes out only through one side of the inner strip 2, as depicted by means of the corresponding arrows.
  • edges 22 and 23 of the inner profile 2 assure contact along the entire outer profile 1 according to the depicted embodiment.
  • the projections 6 of the inner strip 2 are located outside the housings 7 of the fixing bridge 3, such that the inner strip 2 is moved vertically with respect to the first position of the inner strip 2, given that the projections 6 contact the lower part of the fixing bridge 3. Therefore, in this second position the inner strip 2 is located at a lower height than in the first position, corresponding to the height of said projections 6 and the housings 7.
  • the air channel can be closed in the summer position (second position) in order to prevent the generation of vortices which compromise the acoustic characteristic, and the air channel can be opened in the winter position (first position) to balance out the head loss in both positions.
