Definitions

  • the invention relates to a system consisting of a housing, at least one located in the housing surface intermediate element, in particular intermediate floor, and a housing cover for closing the housing, wherein the housing is for an air conditioning system and has at least one open side and the housing includes laterally adjacent housing side surfaces on this open side.
  • Such housings are, for example, housings for mixing and expansion devices, housings for fan coil units, housings for variable volume flow systems, housings for junction boxes or distribution boxes for air-conditioning installations. They are made of sheet metal. In the housing intermediate elements formed as intermediate floors are attached, which are also made of sheet metal and folded laterally. By means of rivets, the shelves are fixed in the housing. Air conditioning components such as fans or heat exchangers can be mounted on the shelves.
  • the disadvantage here is that an exchange of appropriate components in case of failure is time-consuming, since the components in the housing must first be unscrewed from the intermediate floor, which proves to be very cumbersome due to the limited space only. Equally cumbersome is the subsequent assembly of the new component.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a system that allows a simpler exchange of arranged in the housing components.
  • the housing has at least in a region on its inner side for the arrangement of an intermediate element a plurality of projections which are arranged so that they form a groove for insertion of an intermediate element and the intermediate element in the inserted state in this groove in its position is held. Due to the configuration of the invention, the intermediate elements can be easily pushed into the housing during assembly and likewise pulled out again easily and quickly. An exchange is therefore possible in no time. An additional assurance of the intermediate element in the inserted state is not required, since the projections form a groove which holds the intermediate element in its position.
  • the projections which are in contact with the top and the bottom, may for example be arranged directly opposite one another. But it is quite possible that the projections are offset from one another. Of course, it is also possible that a plurality of regions of the housing are provided with projections, so that there are a plurality of grooves and a plurality of intermediate elements in the manner of a shelf can be pushed into the housing.
  • the housings are suitable for both horizontal and vertical installation.
  • the housings may have a height of 100 cm, a width of 40 cm and a depth of 30 cm.

  • the housing would have three housing side surfaces from one side edge to the other side edge of the open side. At least one projection thus extends over essentially an entire housing side surface, while, for example, the one or more adjoining corner regions are not provided with a projection.
  • At least one projection may extend from one side edge of the open side over all housing side surfaces to the other side edge of the open side. If the housing is cuboid, so that extends Projection over the three housing side surfaces and thus also over the two corner areas between two adjacent housing side surfaces.
  • At least one flank of the projection can be formed almost at right angles to the housing side surface assigned to it.
  • a larger contact surface between the intermediate element and the projection is ensured.
  • the flanks of both projections, which are in contact with the intermediate element formed accordingly.
  • the two projections associated with an intermediate element have a different height.
  • the projection with the greater length can take a higher load, which is particularly suitable for horizontal orientation of an intermediate element for the projection carrying this intermediate element.
  • the edge of at least one intermediate element can be sealed off from the respectively adjacent housing side surface by a sealing element.
  • a sealing element As a result, the separated by this intermediate elements housing sections are sealed against each other and so prevents a lateral undesirable flow past.
  • the sealing element has a receiving slot for attachment to the edge of the intermediate element.
  • the sealing element is first attached to the edge. Then, the intermediate element can be inserted into the groove of the housing.
  • the sealing element may for example have a round cross-section.
  • the distance of opposing portions of the housing side surfaces from the open side to the side opposite the open side housing side can decrease.
  • the housing may converge from the open side to the open side opposite housing side surface at an angle of about 3 °.
  • This oblique design facilitates the insertion and withdrawal of an intermediate element, since the intermediate element is only in almost fully inserted state with its two edges over the entire length in contact with the housing.
  • the seal is improved and a stackability of the housing allows, provided that no intermediate elements have been inserted.
  • An air-technical component can be mounted or mounted on at least one intermediate element.
  • the components may be, for example, filters or fans.
  • a filter is provided as an intermediate element, which engages the edge even in the groove. Also may be provided as an intermediate element, a condensate tray, which engages the edge of the groove.
  • the housing may be made of plastic, preferably of acrylonitrile-butadiene-styrene copolymer (ABS).

  • the housing cover may for example consist of plastic, preferably of acrylonitrile-butadiene-styrene copolymer (ABS), or have a sandwich structure consisting of two aluminum layers and an intermediate PE plastic layer.
  • ABS acrylonitrile-butadiene-styrene copolymer
  • the housing may be double-walled. On the one hand, this increases stability even more. On the other hand, there is no need for separate insulation.
  • an insulating layer can be applied to the housing either inside and / or outside in the areas of the housing in which sound transmission is to be prevented.
  • the housing cover may be double-walled.
  • each intermediate element in the region of its edge, which is in contact with the housing cover also has a sealing element.
  • the housing cover on the side facing the interior of the housing also has a plurality of projections which form a groove for receiving the inserted in the housing intermediate element.
  • the intermediate element is also held in its position in the region of the edge which faces the housing cover.
  • the invention also relates to a method for producing a housing according to one of claims 1 to 16.
  • Such housings are, for example, housings for mixing and expansion devices, housings for fan coil units, housings for variable volume flow systems, housings for junction boxes or distribution boxes for air-conditioning installations. They consist of sheet metal, which is folded and riveted or welded in the area of the corners. In the housing intermediate elements formed as intermediate floors are attached, which are also made of sheet metal and folded laterally. By means of rivets, the shelves are fixed in the housing. Air conditioning components such as fans or heat exchangers can be mounted on the shelves.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a method that allows a simpler manufacture of a housing.
  • the housing consists of a thermoplastic material and the housing is produced by thermoforming of a plate-shaped semifinished product.
  • the semifinished product is heated to about 150 degrees Celsius, for example by means of a radiator.
