Definitions

  • the present invention relates to a multi-pane element according to the preamble of independent patent claim 1.
  • the invention relates in particular to a multi-pane insulating element which has at least two surface elements, in particular glass surface elements, which are preferably arranged parallel to one another, a circumferential spacer frame to which the at least two surface elements are preferably connected airtight and vapor-tight, and a pressure compensation system for the space between the multi-pane element.
  • the invention also relates to a pressure equalization system for the space between a multi-pane element, in particular a multi-pane insulating element, and a method for equalizing a pressure difference between an inner volume defined by two surface elements and a spacer frame surrounding the surface elements and an outer volume.
  • the invention also relates to a multi-pane insulating element with a circumferential spacer frame, a cavity formed in the spacer frame being enlarged in such a way that a quantity of desiccant can be accommodated therein, which can accommodate the increased moisture entry through the pressure compensation element can absorb and thus achieve freedom from condensation of hermetically sealed insulating glass elements.
  • the present invention relates in particular to insulating glazing, which is formed by at least two surface elements, preferably arranged parallel to one another, in particular glass surface elements, which are connected to a circumferential spacer frame, preferably airtight and vapor-tight, so that a space is formed between the surface elements and the circumferential spacer frame .
  • the invention further relates to a spacer frame which has an opening which can be closed in an airtight and vapor-tight manner and via which access to parts or components provided in the space enclosed by the surface elements and the spacer frame is possible.
  • Such glazing units are usually used to glaze openings in buildings.
  • Such units must be constructed with great care to prevent the build-up of condensation, the presence of which is considered to be detrimental to the functioning of the glazing system, for reasons of aesthetics, because of the growth of mold and algae and impairment of vision and the light transmittance.
  • the conventional glazing units contain drying agents in order to prevent condensation in the space between the glass panes.
  • the pressure difference could stress or damage the seals or break the glass, typically during of transportation.
  • small tubes are used to provide temporary pressure equalization for insulated glass units.
  • the standard in North America is a stainless steel tube, 12 inches about 30 cm long and 0.020 inch inside diameter, about 0.05 cm, that is circumferentially placed through the gasket to provide a controlled flow path between the interior and the outside environment set up.
  • the units will then sent and can carry out a pressure equalization over a day or longer.
  • the tubes are squeezed to return the unit to a fully sealed condition.
  • the technical literature teaches that if the tube is left open, the airflow will bring in sufficient moisture to remove the desiccant to saturate in a relatively short period of time, resulting in the humidity related failure of the unit. This access of moisture will load the filler with moisture much faster than if the unit were completely sealed.
  • Venting a sight glass unit without a desiccant is not an option as some condensation will then occur under certain circumstances. Sight glass units are particularly sensitive to condensation because the glass panes are transparent and the condensation becomes very evident.
  • the desiccant When an intentional sight glass unit containing desiccant in the internal air space is vented, the desiccant will keep the air within the unit dry until it has absorbed to its capacity. Since conventional desiccants work in two directions, the desiccant initially acts as a moisture sink. In other words, the desiccant acts to equilibrate the unit to a relative humidity so that when a pane becomes cold, water will condense on the pane. This reduces the relative humidity in the unit, which in turn draws more moisture out of the desiccant. The unit then continues to condense resulting in an actual wet looking unit.
  • any glass unit that is sealed will experience an internal pressure change in the glass and "pillow" in response.
  • the amount of movement of the glass required to relieve the pressure change is directly proportional to the thickness of the unit.
  • the length or breadth of the unit is of secondary importance.
  • glass can easily counter this change in pressure if the distance between the panes is 0.5 inches by 1.27 cm. At 1 inch or above, glass breakage tends to occur because there is a greater amount of air in the unit that expands when heated, and even if there is no breakage, there is a resulting increase of stress on the seals, which leads to a higher frequency of failure of the Seal leads. If sight glass units are to be made with a large thickness, these units must be ventilated to relieve pressure differentials.
  • the invention is based on the object of specifying a multi-pane element, in particular in the form of an insulating glazing element, which is easy to manufacture, has a large space in which a sun protection device can be accommodated, has effective pressure compensation, and does not require any additional maintenance effort.
  • a corresponding pressure equalization system is to be specified which enables an effective relief of pressure differences in a multi-disk element without the risk of condensation occurring.
  • this relates to a multi-pane element which has at least two surface elements, such as for example glass panes, which are connected to one another via a spacer frame.

  • Usual spacers are 7 to 10 mm wide.
  • the desiccant it contains is designed to keep the insulating glass unit free of condensation for a period of 20 to 30 years if the edge seal is hermetically sealed.

  • the distance between the surface elements can be from a few cm to over 200 mm.
  • the space between the panes (7) is connected to the outside atmosphere, the rebate space or the interior by means of a pressure equalization system.
  • the pressure equalization takes place in its preferred form by means of an elongated cavity with a very small inner diameter.
  • the pressure compensation system can be designed as a capillary tube.
  • the capillary tube is dimensioned, for example, in such a way that the pressure equalization can take place quickly enough in the event of temperature changes, but that the exchange of air is nevertheless hindered in such a way that the resulting moisture input is reduced to a minimum.

  • a fine filter is preferably also attached in front of the pressure compensation system.
  • this fine filter is hydrophobic. This means that water in liquid form cannot pass through the filter, only in vapor form. In this way, the subsequent pressure equalization system is protected accordingly.

  • the opening options can be attached to the outside of the profiles as well as to the inside. The attachment of the opening option in the area of the openable cover has proven to be particularly advantageous. In this area, access to the desiccant cavities can easily be created.
  • the desiccant can then through the openings are replaced through it. This can be done, for example, by a suction device. Once the desiccant has been removed, new or regenerated desiccant can be reintroduced. As a result, the function of the insulating glass element can be extended for a long time.
  • this relates to insulating glazing, consisting of at least two glass panes 1, 2 and a circumferential spacer frame 3, to which the glass panes are connected airtight and vapor-tight, the distance between the glass panes 1, 2 being greater than 30 mm, wherein the spacer frame 3 has one or more cavities 5 and / or openings that are filled with a desiccant 6, and wherein the space can be opened on at least one side to provide technical equipment for sun protection or glare protection, sound insulation or other requirements to be introduced, and then can be closed again in a vapor-tight manner, and wherein the space between the panes 7 is connected to the outside atmosphere by at least one pressure equalization system 8.
  • the spacer frame 3 can be opened on at least one side by means of a cover.
  • At least one of the two glass panes can be made shorter, the remaining area being designed as a frame 16, 17, 18 with a cover 9.
  • the cover 9 present on the spacer frame 3 can be fastened in such a way that it can transfer static loads from the upper profile to the lower frame profile.
  • the cover 9 can be designed as a profile or as a box.
  • the spacer frame 3 can have such a large cavity 5 that a sufficient amount of desiccant 6 can be filled there.
  • the drive motor 11 can be located inside the cover 9 designed as a box.
  • the drive shaft 15 can be guided through the bottom of the cover 9 by means of an almost airtight passage 14.
  • the drive 11 can be located on the inside of the room.
  • the drive shaft 15 can be guided through a bore in the glass pane 2 by means of an almost airtight passage 14.
  • an additional drying agent package 19 can be located in the connecting line between the space and the outside atmosphere, through which the air flowing in and out is guided.
  • a desiccant can be located in the desiccant package, which can release moisture again to the air flowing through at temperatures from approx. 40 to 50 ° C.
  • the desiccant package can be connected to a solar collector 20 in a thermally conductive manner and thus heated when exposed to sunlight.
  • the desiccant package can be heated by a heating element.
  • the pressure compensation element can consist of a capillary tube wound into a spiral.
  • the pressure compensation element can consist of a valve which enables pressure compensation in the event of overpressure or underpressure.
