Definitions

  • the present invention relates to the housing of a device for conditioning atmospheric air in living and working spaces, which device is housed as a compact unit in the housing.
  • the atmospheric air that is sucked in must be free of dust particles and excess moisture and then be led into the work area in question at a fixed constant temperature. This can be achieved using filters, dryers, heating and cooling elements.
  • the ventilation device is intended in particular for living rooms, and it consists of a housing which is formed from 2 can-shaped halves with tubular connections for sucking in and blowing out the air, in which housing the fan and heating elements are accommodated.
  • the two halves can be made of plastic, but the locking elements are made of metal.
  • the metal locking elements conduct the noise to a considerable extent, so that the noise insulation of the plastic walls is largely null and void.
  • DE-A-3 427 005 describes the use of structural foam components for ventilation and air conditioning systems. These consist entirely of this structural foam. A reinforcement of these elements by external and internal walls has not yet been considered. But if you have to place large systems in a housing of this type, this foam does not have enough mechanical strength. The devices required for a device for conditioning air, such as filters, fans and heat exchangers, are too heavy for this.
  • the need was recognized to install the device in a housing that should consist entirely of insulating plastic, whereby no cold bridge can arise, but according to the invention is characterized in that all walls of the housing from two smooth plates made of hardened polyester resin with woven glass fiber reinforcement exist between which there is a thick layer of hard polyurethane foam, which foam should contain closed vacuoles, and wherein the connection of the narrow edges of the walls is Z-shaped profiled as a lapel bandage with the help of plastic glue.
  • the device for conditioning the atmospheric air is housed in a rectangular housing, which housing consists entirely of plastic without metallic parts, so that no cold bridge can arise.
  • the walls of the housing are formed according to the invention from rectangular wall parts, which consist of two smooth plates made of hardened polyester, which is reinforced by a layer of woven glass fiber within the polyester surface, with a thick homogeneous layer of hard polyurethane foam with closed vacuoles attached between these two polyester plates which was firmly attached to the inner surfaces of the panels by pressure application, as well as all narrow edges of the wall parts are profiled with a so-called wind bandage (rollover bandage), and are connected to the adjacent wall part by means of a layer of plastic glue without any metallic aids.
  • wind bandage rollover bandage
  • the corners are also carried out stably in this way.
  • a housing is formed which is completely smooth on the inside and outside, corrosion-resistant, optimally heat and noise isolating and of low weight, but has a high impact resistance, and its assembly is easily possible even in difficult places. If the housing is to be provided with a door, the same wall parts are used for this, which can be moved laterally as sliding walls, so that they are completely free of cold bridges even in the closed position.
  • the thickness of the wall parts is about 40 mm in total.
  • thermal insulation R of 1.7 m2.h. o C / Kcal measured so that the K value is 0.59.
  • the wall parts are made of aluminum in multiple forms, by inserting glass fiber fabric, between which foamed hard polyurethane is placed, after which the glass fiber fabric is impregnated with liquid polyester resin with hardener under pressure, so that permanent identical wall parts are delivered from the molds.
  • the narrow edges of the wall parts are profiled in a Z-shape as a rollover or wind bandage.
  • the housing is self-supporting and the parts of the conditioning system are attached to the base plate with glue, after which the housing is closed.
  • the housing is resistant to the weather, so that it can also be set up in the open air.
  • FIG. 1 shows a partially opened isometric elevation of the device according to the invention.
  • Figures 2 to 5 show cross sections and shape of the connections.
  • the polyurethane foam filling is indicated with (9).
  • Figure 2 shows a cross section of a wall part with equilateral Z-shaped side edges (8) of the rollover bandage.
  • Figure 3 shows a cross section of a wall part with diagonally attached Z-shaped side edges (8).
  • Figure 4 shows a corner brace
  • Figure 5 shows the association of two wall parts of a linear wall.

Claims (3)

  1. Un dispositif, en forme d'unité compacte, de conditionnement de l'air atmosphérique dans des salles de domicile et de travail, comprenant un boîtier rectangle, danslequel les accessoires pour le conditionnement sont enfermés, ledit boîtier consistant entièrement de matière plastique sans parties métalliques, caractérisé en ce que toutes les parois dudit boîtier (1) consistent de deux tôles lisses de résine polyester rigide avec renforcement de fibres de verre tissues, parmi lesquelles une couche épaisse de mousse rigide (9) de polyuréthane a été posée, ladite mousse comprenant des vacuoles obturées, et les bords (8) d'assemblage des parois sont formés en profils Z, au fin d'assemblage comme un entaillage, raccordé par un joint collé.
  2. Un dispositif selon la revendication 1,caractérisé en ce que l'épaisseur des parties des parois est 40 mm environ, et que le matériel des parois donne une valeur isolante contre la chaleur R d'environ 1.7 m².h.°C /Kcal, donc un coefficient de transmission de chaleur K de 0.59 Kcal/m².h.⁰C seulement.
