Definitions

  • the invention relates to a building glazing with fillable and emptable, controllable thermal insulation device, with at least one window field which, between two glass panes arranged at a distance from one another, has an insulating space which can optionally be filled with a free-flowing filling of insulating particles, the lower end of which is connected to a storage container via a suction conveyor line , from which the insulating particles reach an upper inlet of the insulating space.
  • Venetian blinds and similar devices only insufficiently meet the requirements for a high-performance thermal insulation device, especially since they only prevent the passage of radiation, but without improving the thermal insulation effect of the window field.
  • thermal insulation devices have been developed in which a free-flowing filling of insulating particles is optionally introduced and sucked into an insulating space between two glass panes.
  • This filling on the one hand prevents the passage of radiation in both directions (insulation or shading), so that undesired heating when the sun is too strong and heat loss at low outside temperatures are prevented; on the other hand, the filling made of insulating particles represents an additional thermal insulation layer, the thermal insulation capacity of which, owing to the lack of convection between the insulating particles, is significantly higher than the thermal insulation capacity of an air layer present between the two glass panes.
  • the total energy permeability (g-value) for incident radiation is composed of 1) direct solar energy transmission and 2) secondary emission as a result of solar radiation absorbed in the glazing.
  • the heat balance for incident sunlight from single insulating glass is cheaper than e.g. due to the higher g-value (no heat reflecting coatings). with heat protection glass.
  • the radiation losses are higher in the night hours, although this disadvantage does not come into play when using movable thermal insulation due to its insulating effect.
  • the window field is arranged vertically.
  • the storage container which holds the filling of insulating particles as long as the radiation passage through the window is to be released, is arranged at a distance from the window field and connected to it via a suction conveyor line through which the filling is transported from the window field to the storage container.
  • a pressure delivery line leads from the storage container to the window field in order to promote the filling of insulating particles from the storage container into the window field, if this is necessary.
  • the pressure delivery of the insulating particles from the storage container into the window field causes a considerable mechanical stress on the insulating particles, in particular due to the delivery pressure, which must be chosen so high that clogging of the delivery line is avoided.
  • the insulating particles consequently enter the insulating space in the window field at a relatively high speed and are thereby of a high mechanical quality Subject to wear.
  • the delivery pressure is transferred to the insulation area in the window field and leads to considerable mechanical stress on the glass panes, which consequently must be made correspondingly thick.
  • the object of the invention is therefore to provide a building glazing with controllable thermal insulation of the type mentioned that the greatest possible protection of the insulating particles is guaranteed.
  • the storage container is arranged above the insulation space and has a lower, controllable outlet flap which is connected to the inlet of the insulation space, so that the filling only enters the insulation space under the influence of gravity.
  • the insulating particles are transported very gently in their entire cycle. Since the insulating particles only trickle under the influence of gravity and therefore with very little mechanical energy into the insulating space in the window field as soon as the outlet flap of the storage container is opened, the mechanical stress on the insulating particles is so low that abrasion is largely avoided.
  • the window field and the storage container arranged above it are inclined accordingly to a sloping roof.
  • controllable thermal insulation of a roof glazing can be achieved without the storage container arranged according to the invention above the window field disturbing the external appearance of the building.
  • a plurality of window fields can preferably be arranged side by side, each window field being assigned a separate part of the shared or shared storage container. This enables a separate regulation of the thermal insulation for different window fields.
  • the window panel 1 shown in the drawing forms part of a building glazing and is inclined according to the sloping roof of the building.
  • the window field 1 has frame elements 2 and two glass panes 3 arranged at a distance from one another, between which an insulating space 4 (pane spacing 65 mm for 65 mm thermal insulation layer made of insulating particles) is formed, which serves to hold a filling 5 of insulating particles.
  • These insulating particles are, for example, rigid foam balls according to European patent 306 877.
  • a storage container 6 is also inclined according to the sloping roof and serves to hold the insulating particles.
  • the storage container 6 has a lower, manually or motor-operated outlet flap 7, which is shown in Fig. 2 with solid lines in its closed position. The open position is indicated in Fig. 2 with dashed lines.
  • the outlet flap 7 is connected to the upper inlet of the insulating space 4, so that the filling 5 of insulating particles from the reservoir 6 after the opening of the outlet flap 7 can trickle into the insulating space 4 only under the influence of gravity.
  • the insulating space 4 opens via a controllable lower outlet flap 8 into a collecting chamber 9.
  • a suction conveyor line 10 of high electrical conductivity is led out from the lower region of the collecting chamber 9 and opens with its upwardly conically open end 11 (pipe widening) in the upper region of the storage container 6.
  • FIG. 2 the course of the suction conveyor line is only shown schematically. In practical implementation, it has proven to be advantageous to guide the suction conveyor line 10 upwards in one of the two side frame elements 2, as is indicated in FIG. 1 with a broken line. This eliminates the need to provide pipes running outside the window field 1.
  • an upstream filter 12 (also an air drying filter) is connected to a suction fan 13, which is only schematically indicated in FIG. through an insulating body designed as a flow channel, through the suction conveyor line 10 into the reservoir 6.
  • the outlet flap 7 must be closed to build up the vacuum.
  • the insulation space 4 of the window field 1 is free of insulation particles and thus completely permeable to the entire incident solar radiation. If further heat input from solar radiation is to be prevented, for example in order to avoid undesired further heating of the interior of the building, or if heat radiation from the building to the outside at low outside temperatures due to radiation losses is to be avoided, the insulating space 4 is filled with the insulating particles.
  • the outlet flap 7 is opened by a flap drive (not shown).
  • the filling 5 of insulation particles trickles down and fills the insulation space 4.
  • the collecting chamber 9 can be provided with a ventilation opening 14.
  • the space 15 located at the upper end of the insulating space 4 below the outlet flap 7 in the upper region of the window field 1 can be provided with a ventilation opening 16 in order to ventilate the insulating space 4 when the filling of insulating particles flows downwards.
  • the suction conveyor line 10 has a conical tube widening 11 at the particle outlet in the storage container 6.
  • the suction conveyor line 10 can be designed as a suction hose.
  • the suction hose or hoses can be equipped with an integrated copper wire in order to obtain a higher electrical conductivity. In this way, any electrostatic charge that arises is dissipated by rubbing the insulating particles on the suction hose and with one another, in particular in the case of aggressive material to be conveyed.
  • the suction conveyor line 10 can be designed with a line diameter that increases gradually or conically in the conveying direction, so that the insulating particles are gentle due to low speed and because of the conical or conical expansion at the end 11 of the suction conveyor line 10 without impact even in the storage container 6 without compression be moved.
  • a manual or motor-operated closure flap 17 is arranged at the beginning of the suction conveyor line 10.
  • the collecting chamber 9 is provided with insulation 18 and designed as a flow channel.
  • a special fabric 19 is arranged in the collecting chamber 9.
  • the window field is arranged with an inclination of at least 25 °.
  • a thermal separating plate 20 At the transition from the storage container 6 to the insulating space 4 there is a thermal separating plate 20.
  • the window field 1 is supported by a beam 21.
