Definitions

  • the invention relates to a Klimastand réelle specified in the preamble of claim 1 genus.
  • Hygiene-relevant rooms as they occur for example in medicine, the food industry, the pharmaceutical industry or the like. Must be supplied for hygienic reasons with a temperature-controlled sterile indoor air, so that no harmful particles, such as germs, can propagate in space.
  • a climate control unit is usually installed in hygiene-relevant space. Since there is often little space in hygiene-relevant rooms, such climatic equipment must be very compact and space-saving.
  • the Klimastand réelle shown there comprises a housing with a triangular base surface corresponding to its footprint for space-saving installation of the Klimastand réelles in a corner of the hygiene-relevant space.
  • the base is limited by a front edge and by two at least approximately at right angles to a common point of intersection tapered rear side legs, the side legs of the front edge facing each having a front end. Through the front ends runs a triangular baseline.
  • the problem here is that on the one hand, the possible length of the near-wall triangle legs is limited, since not as much wall space may be covered during installation.
  • the interior volume of the housing is limited, so that not all components required to produce a temperature-controlled sterile room air can be accommodated in the housing, or that the components housed there are undersized for reasons of space.
  • This has the consequence, for example, that on hot summer days, the room air is not sufficiently cooled, the room air is not sufficiently heated on cold winter days and the room air can not be kept sufficiently sterile overall. This manifests itself, for example, in the fact that no prefiltration of the outside air is provided in said climatic control unit.
  • the triangular basic shape requires an outside air supply from the back side, which collides with the installation target in a room corner.
  • the insides of the housing of the climate control unit serve as an air duct.
  • the problem here is that in particular in the corners and edges of the housing dirt, for example in the form of dust, bacteria, microbes, or the like., Accumulate and affect the air quality.
  • the cleaning of the housing interior can be cumbersome or even impossible due to the large number of housed in the housing components.
  • it must be ensured structurally very complex that the housing is impermeable to air, so that no untreated air leakage from the housing interior in the hygiene-relevant space can flow.
  • the invention has the object of developing a generic Klimastand réelle such that with space-saving design, the generation of a temperature sterile sterile air is independent of environmental influences possible.
  • the side legs each have a leg length which measured between the intersection and their front ends is at most about 100 cm.
  • the front edge is through two opposite ends limited and has between them a front edge length, wherein the front edge is located at a middle distance to the triangular baseline.
  • the front edge length and the average distance are dimensioned such that the base surface of the housing has an area of at least about 5500 cm 2 .
  • the base has no acute corners, which take up space, but do not provide useful space for the accommodation of components of the air treatment device. Due to the comparatively large surface area of the base area with still small floor space requirement, all components required for filtering and air conditioning can be accommodated in the housing of the climatic control unit to produce a temperature-controlled sterile room air. In this case, the components can be dimensioned such that the room air always meets the requirements imposed on the hygiene-relevant space regardless of environmental influences. At the same time is achieved by the above-mentioned embodiment of the housing that the climate control device with a small footprint in a corner of the hygiene-relevant space is set up.
  • the point of intersection, the front ends of the rear side legs and the ends of the front edges define a pentagon defining the base surface, leading front side legs between the front ends of the rear side legs and the adjacent ends of the front edge front side surfaces of the housing adjacent.
  • the pentagon is expediently a rectilinear and in particular mirror-symmetrical pentagon.
  • the front side legs are at an angle of about 135 ° to the front edge and in particular orthogonal to the rear Side legs.
  • the front side legs are thus at least approximately orthogonal to the adjoining room walls in the installation state of the climate control device, so that the need for wall footprint in the installation space is minimized.
  • the front edge and the front side legs are straight. This results in a simple producible basic shape of the base, so that the overall housing is easy to produce.
  • the base is large enough to provide an interior volume of the housing, in which all components required for filtering and air conditioning can be accommodated, and at the same time the base is cut so that the climate control unit can be placed in a space-saving in the corner of hygiene relevant space.
  • the recirculation inlet and the air conditioning outlet are arranged in a preferred embodiment on the front surface.
  • the recirculation air inlet and the air-conditioning outlet are arranged on the side of the housing facing the hygiene-relevant space, so that airflow from the conditioned air flowing from the recirculation inlet into the room and the circulated air flowing out of the room into the recirculation inlet are formed in the hygiene-relevant space.
  • a good exchange of air in the hygiene-relevant space can be carried out in a simple manner, so that always temperate sterile room air is available.
  • the outside air inlet is arranged on one of the front side surfaces. This makes it possible to place the climate control unit completely in the corner to save space.

  • the second and the third filter of the filter unit are arranged downstream of the heat exchanger and in particular directly adjacent to the air-conditioning outlet. The tempered mixed air is thereby filtered to the desired quality level.
  • these two filters are located in the immediate area of the climatic air outlet and therefore easily accessible there for maintenance purposes.
  • the first of the three filters is arranged as a pre-filter between the mixing chamber and the heat exchanger.
  • each of the filters is aligned approximately horizontally through the mixed air flow approximately orthogonal to the base.
  • a flow channel which is separate from the housing is arranged in the housing, wherein the flow channel connects the outside air inlet and the recirculation air inlet with the air-conditioning outlet.
