Definitions

  • the present invention relates to a multi-disk element according to the preamble of independent claim 1.
  • the invention particularly relates to a multi-pane insulating element, which at least two preferably parallel to each other surface elements, in particular glass surface elements, a circumferential spacer frame to which the at least two surface elements are preferably connected air and vapor-tight, and a pressure compensation system for the space of the multi-disk element.
  • the invention further relates to a pressure equalization system for the intermediate space of a multi-disk element, in particular multi-disk insulating element, and a method for equalizing a pressure difference between one of two surface elements and a spacer frame surrounding the spacer frame defined inner volume and an outer volume.
  • the invention further relates to a multi-disk insulating member having a peripheral spacer frame, wherein a cavity formed in the spacer frame is enlarged so as to house therein a desiccant amount can be, which can absorb the increased moisture input through the pressure compensation element and thus achieves a condensation of hermetically sealed insulating glass elements.
  • the present invention particularly relates to an insulating glazing, which is formed by at least two surface elements preferably arranged parallel to one another, in particular glass surface elements, which are preferably air-tight and vapor-tight on a circumferential spacer frame, so that a gap is formed between the surface elements and the circumferential spacer frame ,
  • the invention further relates to a spacer frame which has an air- and vapor-tight closable opening, via which access to optionally provided in the space enclosed by the surface elements and the spacer frame space components or components is possible.
  • Such glazing units are commonly used to glaze openings in buildings. However, such units must be constructed with great care to prevent build-up of condensation, the presence of which is considered to be detrimental to the operation of the glazing system, for aesthetics, mold and algae growth and vision impairments of light transmittance.
  • the conventional glazing units contain drying agents to prevent condensation in the space between the panes of glass.
  • the pressure differential could stress or damage the seals or break the glass, typically during of transport.
  • 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 long by about 30 inches long and with an inside diameter of 0.020 inches about 0.05 inches that is brought through the seal in the perimeter area to provide a controlled flow path between to set up the interior and the outside environment.
  • the units will then be shipped and can pressure equalize for a day or more.
  • the tubes are then squeezed to return the unit to a fully sealed condition.
  • the technical literature teaches that when the tube is left open the air flow will add sufficient moisture to the desiccant to saturate in a relatively short period of time, resulting in the moisture related failure of the unit. This access of moisture will load the filler much faster with moisture than if the unit is completely sealed.
  • Venting a sight glass unit without a desiccant is not an option, as under certain circumstances, some condensation will then occur. Sight glass units are particularly sensitive to condensation because the glass sheets are transparent and the condensation becomes very obvious.
  • the desiccant When a desired sight glass unit containing desiccants in the internal air space is vented, the desiccant will keep the air dry inside the unit until it has absorbed its capacity. Since conventional desiccants work in two directions, the desiccant initially acts as a moisture sink. In other words, the desiccant acts to balance the unit to a relative humidity such that when a disk becomes cold, water will condense on the disk. This reduces the relative humidity in the unit, which in turn pulls more moisture out of the desiccant. The unit then condenses further, resulting in an actual wet-looking unit.
  • any glass unit that is sealed will be subject to 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 width of the unit is of secondary importance. In the day-to-day sequence, glass can easily encounter this pressure change when the distance between the panes is 0.5 inches by 1.27 cm. Glass breakage typically occurs at 1 inch 2.54 cm or more, as there is a greater amount of air in the unit that expands when heated, and there is a consequent increase even if no break occurs at Load on the seals, which leads to a higher frequency of failure of the seal. If sight glass units of large thickness are to be manufactured, these units must be ventilated to relieve pressure differences.
  • the gap can be supplied for example by means of ventilation devices with dried air, and thus compensate for the existing pressure difference and the risk of condensation.
  • this technique is very complex and requires constant monitoring and power supply.
  • Another way is to flush the space with outside air.

  • this relates to an insulating glazing, comprising at least two glass panes 1, 2 and a peripheral spacer frame 3, to which the glass panes are connected in a vapor-tight and vapor-tight manner, wherein the distance between the panes 1, 2 is greater than 30 mm, wherein the spacer frame 3 has one or more cavities 5 and / or openings which are filled with a desiccant 6, and wherein the gap can be opened on at least one side to technical devices for the sun or glare protection, sound insulation or other requirements can be introduced, and then closed again vapor-tight, and wherein the disc space 7 is connected to at least one pressure equalization system 8 with the outside atmosphere.
  • the spacer frame 3 can be opened on at least one side by means of a lid.
  • At least one of the two glass panes can be made shorter, wherein the remaining area is designed as a frame 16, 17, 18 with lid 9.
  • the lid 9 present on the spacer frame 3 can be fixed so that it can transmit static loads from the upper profile to the lower frame profile.
  • the lid 9 may be formed as a profile or as a box.
  • the spacer frame 3 may have such a large cavity 5 that there can be filled sufficiently desiccant 6.
  • the drive motor 11 may be located within the lid 9 formed as a box.
  • the drive shaft 15 can be guided by means of a nearly airtight passage 14 through the bottom of the lid 9.
  • the drive 11 may be located on the inside of the room.
  • the drive shaft 15 can be guided by means of a nearly airtight passage 14 through a hole in the glass pane 2.
  • an additional desiccant package 19 can be located in the connecting line between the intermediate space and the outer atmosphere through which the incoming and outgoing air is guided.
  • a desiccant may be present in the desiccant package, which can release moisture back to the air flowing through at temperatures as low as about 40 to 50 ° C.
  • the desiccant package may be thermally conductively connected to a solar collector 20 and thus heated when exposed to sunlight.
  • the desiccant package can be heated by a heating element.
  • the pressure compensation element may consist of a spiral wound capillary tube.
  • the pressure compensation element may consist of a valve which allows pressure equalization at positive or negative pressure.
