Definitions

  • the present invention relates to a multi-pane element, in particular a multi-pane insulating element, which has at least two planar elements, in particular glass planar elements, which are preferably arranged parallel to one another, a circumferential spacer frame to which the at least two planar elements are preferably connected in an airtight and vapor-tight manner, and a pressure equalization system for the space between the Has multi-disc element.
  • the pamphlet EP 1 978 201 A2 relates to a building opening (window, door, shop window, etc.) with a first chamber formed by one or more panes of glass, on the outside of which a second chamber is attached, which forms an intermediate space with the first chamber and which is watertight but not evacuated , and into which a thin curtain wound on a winding roller and having solar-ray shielding properties can be inserted from above.
  • the pamphlet WO 2016/091258 A1 relates to a multi-pane composite consisting of at least one additional pane, which consists of single-pane glass or insulating glass, and at least one base pane, which consists of single-pane glazing or an insulating glass composite.
  • a cavity is formed between the attachment pane and the base pane, the cavity being closed by means of a spacer frame is established between the front pane and the base pane.
  • the spacer frame is angled, with this having a leg which is connected to the base glass by adhesion or contact pressure and there is a step between the spacer frame and the base glass, the multi-pane composite being held in the area of the step in the rebate space of profile bodies and windows or facades.
  • Glazing units are commonly used to glaze openings in buildings. However, 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 operation of the glazing system for aesthetic reasons, mold and algae growth and visual impairments of light transmittance.
  • conventional glazing units contain desiccants to prevent condensation in the space between the panes of glass.
  • 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 about 0.05 cm inside diameter, that is placed through the seal at the perimeter to provide a controlled flow path between the interior and the exterior environment set up.
  • the units are then shipped and allowed to equalize for a day or more.
  • the tubes are crimped to restore the unit to a fully sealed condition.
  • the technical literature teaches that if the tube is left open the air flow will entrain sufficient moisture to cause the desiccant to deteriorate to saturate in a relatively short period of time, resulting in the moisture-related failure of the unit.
  • 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 condensation becomes very apparent.
  • the desiccant will keep the air inside the unit dry until it has absorbed close 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 such that when a pane gets cold, water will condense on the pane. This lowers 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 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 width of the unit is of secondary importance.
  • glass can easily meet this pressure change when the distance between the panes is 0.5 inch 1.27 cm.
  • glass breakage tends to occur because there is a greater amount of air in the unit that expands when heated, and even if breakage does not occur, there is an increase resulting therefrom of stress on the seals leading to a higher frequency of seal failure.
  • When heavy gauge sight glass units are to be manufactured these units must be vented 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 produce, has a large space in which a sun protection device can be accommodated, has effective pressure equalization and requires no additional maintenance effort.
  • this relates to a multi-pane element which has at least two surface elements, such as glass panes, which are connected to one another via a spacer frame.
  • the surface elements can be sealed to the spacer frame, for example, by means of a vapor-tight seal (eg butyl) and an additional adhesive (eg silicone or thiocol).
  • a vapor-tight seal eg butyl
  • an additional adhesive eg silicone or thiocol
  • a glass pane as a surface element
  • another pane of insulating glass can also be used, for example to further adjust the thermal insulation properties.
  • the spacer frame is made of a vapor-tight material, e.g., aluminum, stainless steel, plastic, and is formed with a cavity(s) or an opening(s).
  • One or more cavities or openings are filled with desiccant.
  • Customary spacers have a width of 7 to 10 mm.
  • the desiccant it contains is designed to keep the insulating glass unit free of condensate over a period of 20 to 30 years with hermetically sealed edge seals.
  • the spacer, and thus the available space for the desiccant is significantly enlarged.
  • the width of the spacer in the proposed embodiment is at least 20 mm. Depending on the element size, larger widths of 30 mm and more are also possible.
  • the distance between the surface elements is at least 50 mm.
  • the space between the panes (7) is connected to the outside atmosphere, the rebate area or the interior by means of a pressure equalization system.
  • the pressure equalization takes place 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 in such a way that the pressure can be equalized quickly enough in the event of temperature changes, but the exchange of air is still impeded in such a way that the resulting moisture input is reduced to a minimum.
  • the capillary tube can be from a few cm long to more than 1 m long.
  • the inside diameter of the capillary tube is preferably between 0.5 mm and 2 mm.
  • the capillary tube can be designed either as a straight piece of tube, as a single or multiply bent piece of tube, or as a piece of tube coiled into a spiral. Instead of a spirally bent piece of pipe, the hollow space can also be produced by turning parts similar to a thread.
  • the use of two or more capillary tubes arranged in parallel has proven particularly advantageous. As a result, the function of the pressure equalization system can be further improved. In the case of small pressure differences, the system reacts very sluggishly. Only at higher pressures is a noticeable pressure equalization, and thus air exchange, made possible. Furthermore, the use of several capillary tubes has the advantage that if one of the tubes fails, there are still other tubes that fulfill their function and thus increased functional reliability is achieved.
  • the pressure equalization can also be effected by a valve that opens or closes the connection from a certain positive or negative pressure, and thus allows a controlled pressure equalization.
  • a fine filter is preferably installed in front of the pressure equalization system.
  • this fine filter is hydrophobic. This means that water in liquid form cannot pass through the filter, only in vapor form. This protects the subsequent pressure equalization system accordingly.
  • the amount of desiccant contained in the cavity of the spacer frame is such that it can keep the space between the panes dry over a long period of use.
  • the spacer frame is provided with an openable but vapour-tight cover on one long side. Ideally, this opening is made on the top of the element.
  • the cover can be designed as a simple plate, or as a profile or box. The cover is removed to install or remove the sun protection system or other technical equipment. If a sun protection system is installed, it is preferably attached to the underside of the cover so that it can be inserted easily and precisely into the gap. External venetian blind systems or suitable fabric or foil roller blinds can be used as sun protection.
  • sun protection systems In order to enable these sun protection systems or other technical devices to be driven, further sealed penetrations can be introduced in the glass or in the frame profile.
  • the drive of sun protection systems is best done automatically, for example, by means of electric motors. There are several positions and installation positions for motors.
  • the motor is mounted directly on the sun protection system.
  • this has the disadvantage that the replacement of a motor in the event of a defect is somewhat complex and that the motor is located in the hot space between the panes, which can have a negative impact on the service life.
  • the motor is installed in a room above the sun protection system.
  • the cover is designed as a kind of box. While the sun protection system is attached to the box below the floor, the motor is located inside the box.
  • the drive from the motor to the sun protection takes place, for example, via two deflection gears and an airtight passage of the drive shaft.
  • the space in which the engine is located is connected to the outside atmosphere via the rebate space and is therefore somewhat cooler than in the space between the panes.
  • the motor can be replaced without opening the space between the panes. However, this requires access to the upper area of the window element.
  • the box can be removed for repairs to the sun protection itself.
  • the motor for the drive of the sun protection system is installed on the inside of the room.
  • an airtight passage of the drive shaft from the sun protection system to the outside is installed.
  • the motor is then easily accessible on the room side. In the event of a defect in the motor, it can easily be replaced there. Repairs to the sun protection itself are carried out as in the first variant.
  • the pressure compensation system can have an air drying unit with a regenerative desiccant (desiccant pack) and an air line system, via which air can be exchanged between the intermediate space of the multi-pane element and the outside atmosphere.
  • the air line system can be designed in such a way that the air to be communicated during the exchange of air between the intermediate space and the outside atmosphere passes through the desiccant (desiccant package) of the at least one air drying unit.
  • the at least one air drying unit can be assigned an active and/or passive heating system, with which the desiccant can preferably be heated or heated as required, in order in this way to bring about a regeneration of the desiccant.

  • a desiccant that can be regenerated from a temperature of 40 to 50° C. for example a desiccant based on an amorphous silicon dioxide, is particularly suitable as a desiccant.

According to embodiments of the multi-disk element 22 according to the invention, this is provided with a pressure compensation system 100 . According to further embodiments, a sun protection system 10 is integrated in the space 7 between the panes.
  • Insulating glass panes are well known from the construction industry. As a rule, insulating glass panes consist of at least two panes of glass that are connected to one another by an edge seal.
  • the edge seal is designed to be almost airtight and vapour-tight and hermetically seals the gap to the outside atmosphere. This is necessary in order to minimize the entry of moisture into the space as far as possible.
  • desiccant In order to protect the insulating glass pane from condensate for years to come, there is a defined amount of desiccant in the space between them. This desiccant is usually housed in the edge bond. The amount of desiccant is sufficient to keep a hermetically sealed insulating glass pane free of condensate for around 20 to 30 years.
  • the edge seal itself usually consists of a spacer profile made of plastic or metal, as well as a primary and secondary seal. Due to static requirements, this version is limited to insulating glass panes with a space between the panes of a few cm.
