Definitions

  • the invention refers to a recuperating air-conditioning device, preferably a surface ceiling distributor, which is used in distribution air-cooling, heating or ventilating systems, in particular of accomodation rooms.
  • Distribution system means a connection with an air-valve within each accomodation room, into which the air is blown, or the air is collected, in separate systems.
  • the recuperating device is by means of a pipe connected with a surface ceiling distributor.
  • the surface ceiling air-distributor is via pipes connected to air-valve chambers.
  • Air-valve chambers, into which air-valves are insertable, are arranged on the ceiling or on walls or on the floor of each accomodation rooms.
  • the purpose of the invention is to improve a housing of a surface ceiling distributor in order to reduce vibrations and noise, to assure uniform air-flow on all outputs, as well as to minimize the risk of bacterial infections of the air.
  • a further task of the invention is to improve protection against withdrawal of the pipe from the surface ceiling air-distributor.
  • a known ceiling surface air-distributor is furnished with a housing in the form of a parallelepiped with one main pipe connector and at least three pipe connectors aligned in one line or several lines. Pipe connectors are arranged on separate plates, so that each plate can be mounted onto said housing in such manner that the central axis of the main pipe connector and the central axis of each smaller pipe connectors extend either perpendicular or parallel with respect to each other.
  • the ceiling surface air distributor is made of zinc-plated metal sheet.
  • the shell of the housing consists of several parts, which are interconnected by means of screws or rivets. Pipe connectors and the main pipe connector are attached to the housing by means of screws or rivets.
  • the interior of the housing is covered with materials which are used for reduction of noise.
  • Such assembled construction of the housing is an essential deficiency, since its own frequency of vibrations by intensive air-flow enhances vibrations and noise. Housing in the shape of parallelepiped leads to turbulence of air and huge air-flow resistance. Folded contacts of such assembled construction and noise-reducing claddings within the housing are highly risky in view of generating various potentially dangerous biologic materials.
  • the metallic construction is due to air-air flow energized by static electricity, which attracts the particles in the air with the opposite polarization.
  • a further deficiency of such solution is a protector in the shape of the letter U.
  • the pipe connectors are available in three lines, such protector cannot been inserted in two lines, when it is located closely to the ceiling or the wall.
  • a surface ceiling air-distributor comprises a housing in the form of parallelepiped, a main pipe connector as well as two separators, which are located apart from each other and are integrated within said housing, wherein the first one extends from the top of the housing and the second one extends from the bottom of said housing.
  • a shell of the housing is corrugated and furnished with rounded transitions between each sidewall and each adjacent one.
  • the housing, a plate and a plate with pipe connectors are all made of an antistatic and anti-bacteriologic thermoplastic material, preferably of polyethylene.
  • a protector is conceived as an interrupted elastic ring having two plates, which in the middle form a semi-circle, and the edge is in the one side sharp and on the other side rounded.
  • the used material is a thermoplastic material with good elasticity.
  • Such surface ceiling air-distributor with its shape in the form of parallelepiped, with separators and a corrugated shell represents a compact construction, which is capable to essentially reduce vibrations and noise even by intensive air-flow.
  • the air-flow resistance is essentially reduced.
  • measuring of the air-flow in particular pipe connectors shows that the air-flow is uniform with only small deviations. Additional claddings for reducing of noise are not necessary.
  • the used material prevents the formation of various biologic organisms, which might jeopardize the health. Also the particles, which are generated by static electricity, are not present.
  • the protector according to the invention is placed onto each pipe connector prior to mounting the surface ceiling distributor in such manner that the sharp edge is faced towards the housing.
  • a notch on the pipe connector enables the plate of the protector to be moved into the pipe connector, so that the semi-circular portion of the plate protrudes over the inner diameter of the pipe connectors, while the residual portion of the plate is placed inside of the interrupted pipe connector.
  • corrugated pipes are inserted. Displacement of the tube towards the housing is due to said rounded edge followed by displacing the semi-circular area of the plate, which enables the elastic ring to move outwardly.
  • the sharp edge on the semi-circular area of the plate prevents the elastic ring from being displaced outwardly, when the pipe is withdrawn. If the withdrawal of the pipe is desired, said elastic ring can be moved apart, e.g. by means of a screwdriver.
  • a surface ceiling air-distributor is shown in Fig. 1 and comprises a housing 1 in the form of a parallelepiped, a main pipe connector 6 with an attached plate 5 and a plate 2 with pipe connectors with at least three lines of pipe connectors 3 aligned along a line or several lines. Protectors are placed on said pipe connectors.
  • the shell of said casing 1 is corrugated and furnished with rounded transitions from each sidewall into each adjacent one.
  • FIG. 2 said surface ceiling air-distributor is shown in a cross-section along the line I-I.
  • a bottom separator 7 is placed within said housing 1 and protrudes from the bottom area thereof, wherein the top separator 8 is located at a distance apart from it regarding the width of the housing 1 and protrudes from the top area of the housing, and wherein said separators are integral parts of the housing 1.
  • the walls of said separators 7, 8 are inclined and on the top semi-circularly interconnected.
  • the width and the height of the separators 7, 8 and the distance between them are determined in dependency of each desired air-flow.
  • the width and the height of the separators 7, 8 correspond to approximately a half of the height of the housing 1.
  • a small separator 9 can be placed in the front portion of the housing 1, namely in front of the plate 2 with pipe connectors.
  • Said housing 1, said plate 5 and the plate 2 with pipe connectors all consist of an anti-static and anti-bacteriologic thermoplastic material, preferably of polyethylene.
  • Fig. 3 said surface ceiling air-distributor is shown in cross-section along the line II-II.
  • the height of the upper separator 8 is adjacent to the housing walls marked as H min , and in the middle as H max , wherein the difference between them may be up to 30%.
  • the protector 4 is shown in Fig. 4 and 5 , and is conceived as an interrupted elastic ring with two plates, which are in the middle semi-circularly shaped, wherein the edge is on the one side sharp and on the other side slightly rounded.
  • the used material is a thermoplastic material with good elasticity.
