Definitions

  • the invention relates to a device for controlling the atmosphere in a space which is partially bounded by at least one glass component and separated from the environment, with at least one connection between the space and the environment, and with at least one electrically actuated valve associated with the connection, which is connected to an electrical control unit.
  • the invention relates to a double glazing and a lamp with such a device.
  • an insulating glazing also called insulating glass, laminated glass or glass panel
  • insulating glass laminated glass or glass panel
  • it is known (see, eg DE 38 44 639 A1 )
  • large-scale glazing for large windows or in facade construction, for glass facades, resulting from pressure differences considerable deformations of the glass panes, which then, when the pressure in the space between the glass sheets is higher than the ambient pressure, bulge outward or Conversely, if the ambient pressure is higher than the pressure in the space, buckle inward.
  • the bulges or tensions are, as has been shown in practice, the greater, the greater the distance between the glass panes. These deformations can lead to glass breakage or leaks in the system. As a result, moisture from the environment in the limited space from the glass panes, which can lead to a condensation of water vapor and thus turbidity.
  • Another problem of penetrated moisture arises when in the space between the glass panes elements, such as blinds, slats, or on the inner surface of the glass pane coatings, such as metal vapor coatings (see, eg DE 101 41 879 C1 ) intended are because then due to the moisture adverse effects, especially corrosion effects arise.
  • the deformations of the glass panes can also cause these elements rub during pivoting on the inner surfaces of the glass panes, if they are curved inwardly due to a lower internal pressure, which on the one hand this Elements and on the other hand any internal coatings on the glass sheets are mechanically impaired.
  • Another problem because of the large deformation at larger distances between the glass sheets is that then selected for the sound insulation and thermal insulation optimal distances between the glass sheets can not be met, so that, apart from the adverse increased humidity in the space between the glass sheets , also by the no longer optimal distances the Dämmagonist be worsened.
  • glass components not only glass components such as glass sheets of quartz glass and the like are to be understood, but also components made of transparent plastics, such as acrylic glass.
  • valve device in a line between a controller and the controlled space, wherein the valve device is controlled by the controller such that in short-term pressure surges, such as the slamming of doors, no pressure-compensating open connection between the disc space and the environment is established ,
  • the valve device and the controller are present outside the double glazing, and in particular to be controlled with a single control multiple glazing units via separate pressure equalization lines and therein valve devices.
  • this is disadvantageous in terms of the separate installation of the controller, the valve devices and the separate lines.
  • an apparatus for keeping dry an air gap of multiple glazing outside this multiple glazing is a relatively complex valve device with a heatable expandable valve body, which holds a passage from the air gap to the environment, a desiccant area in the cold state, but closes this passage when heated, so that regenerates the desiccant in this phase by heating can be.
  • the air gap of the respective multiple glazing is thus constantly connected to the environment in the normal state, so that a continuous pressure equalization can take place, but also moisture can constantly penetrate into the system and must be absorbed by the desiccant.
  • the heating process for the purpose of opening the valve and regenerating the desiccant is initiated by an apparently manually operated switch.
  • the invention provides a device as defined in claim 1 before.
  • Advantageous embodiments and further developments are specified in the dependent claims.
  • an "integrated" electrical control unit accomplishes automatic actuation of a valve located directly in the communication passage between the space and the environment, for example, to balance between the pressure in the room and the pressure of the environment. if necessary, also to flush relatively humid air in the room and to divert it into the environment and to introduce dry air from the environment into the room.
  • a valve located directly in the communication passage between the space and the environment, for example, to balance between the pressure in the room and the pressure of the environment. if necessary, also to flush relatively humid air in the room and to divert it into the environment and to introduce dry air from the environment into the room.
  • the built-in electric control unit hardly causes any extra work, which the Energy supply arrives. Even with freestanding lights, especially outdoor lights, such as wall lights, the ambient conditions are exposed, of course, already given a supply of electrical energy, so that there are no special additional measures necessary for the energy supply of the built-in control unit and the electrically actuated valve.
  • An advantage is also that it is possible to build insulating glazings with a large distance between the glass panes, which in turn allows components with greater space requirements to be installed in this gap, apart from the fact that by correspondingly large distances of the glass panes also particularly good heat and soundproofing can be achieved.
  • a large distance between them makes it possible to install particularly wide and stable slats or roller blinds in the intermediate space. If particularly wide, fixed lamellae are possible, larger lamellae lengths are in turn made possible without the lamellae requiring separate reinforcements or supports at intermediate points.
  • Improved thermal insulation values can be achieved as mentioned by the increased distance (in particular 25 mm and more) between the glass panes, wherein the distance upwards a limit is given by the fact that no convection in the space should occur. In the case of solar shading in the space such convection of the gas content or air content is additionally hindered. Experiments have shown that an optimum distance for best thermal insulation values is about 40 mm to 60 mm. At such distances then the installation of the control unit and the valve in a connection bar is particularly easy to accomplish, since then the connection bar has a corresponding thickness.
  • insulating glazings comparatively thin glass panes can advantageously be used in the case of the control equipment according to the invention, since the pressure differences between the space and the surroundings can be avoided or kept extremely small, and because of the good insulating properties, insulating glazings can also be used without difficulty instead of with three panes two glass panes are realized; This can also be a significant material savings and easier handling of the glass or insulating glazing can be achieved.
  • not so stringent scale to the quality of the adhesive bond of the glass panes in the area of the spacer strips or frame strips create, just because hardly more pressure differences occur during operation and an absolute gas-tightness is no longer required.
  • the control unit can automatically close or open the at least one valve at predetermined time intervals, for which purpose it may include a timer (timer) or an (electronic) clock.
  • the time intervals can be derived in particular from a clock generator as a timer. It is possible to open the valve at intervals of several minutes, to ensure a pressure equalization, and then close again, taking into account that a pressure difference builds up not very suddenly, but very slowly, for about a day.
  • control unit depends on measured parameters, such as internal and external pressure or pressure difference, indoor and outdoor temperature and humidity, which actuates at least one valve.
  • the at least one valve can be opened when the difference between the internal pressure and the ambient pressure reaches a predetermined limit, which can be accomplished by pressure measurement in space as well as in the environment or directly by means of a pressure difference measurement.
  • a predetermined limit can be accomplished by pressure measurement in space as well as in the environment or directly by means of a pressure difference measurement.
