Abstract

In a heat-insulation and sound-proofing window, there are devices which allow room aeration and room deaeration, with recovery of heat from the waste air, by the timed method on the thermosiphon principle. For a more effective heat recovery, the horizontal soffit frame parts, which surround the two wings of a box-type window together with their fixed frames, accommodate slotted tubes which are rotatably mounted in foam bodies and which control the air movement between the box interior, the room side and the outside.

Description

Password: "Clock-controlled heat recovery

winnungsfenster "thermal and soundproof windows with devices, a room ventilation system based on the thermo-siphon principle with heat recovery from the exhaust air.

The invention has set itself the task of the ventilation function a heat and sound insulated window, preferably a box or composite window, with heat recovery from the exhaust air of a room without the heat and to impair the soundproofing function of the window with the aim of creating a room hygienic to create a good climate while saving as much heating energy as possible.

There are essentially three ventilation systems in the prior art in connection or on a window, the latter of which is a heat recovery includes.

The first group has been known as "permanent ventilation" for a long time. known. This ventilation device is usually located across the top over your window and, depending on the size and # number-of #, leaves it at right angles to its longitudinal axis The width of the air ducts, which can be adjusted, allows more or less outside air get directly into the interior of the room.

The passage volume of the air depends on the prevailing climatic conditions Conditions and does not include any heat recovery. Noise protection is ever available according to equipment.

The second group is a device of a similar nature and is for regulation the air flow rate is equipped with a fan that can be switched in stages. she does not contain heat recovery, generates drafts and brings during the heating season constant. Cold air into the room.

The third group works on the same principle, but has in Your fan housing has a heat pipe or similar element integrated, which when separated Guiding the supply and exhaust air from the latter removes heat and supplies it to the supply air. The efficiency of such a box, which has become known under the name "Klimabox" Ventilation device is not only dependent on the prevailing atmospheric conditions depending, but also on the air passage speed or residence time in the climate box itself.

The latter conditions are understandably unfavorable because here - as with the first group - the air duct only inside the fan housing can take place, which due to the spatial conditions on one side of a window, preferably above the window, cannot be made with a large volume. Between Upper edge of Ferster and Lintel is very little space in the height and very often located there is a roller shutter.

The invention has set itself the task that after the jam of the technology described above, to remedy the deficiencies that may arise and has essentially solved this as described below.

The object of the present invention is essentially as follows as described solved: In a multiple-glazed window with large pane spacing, preferably with a box or composite window, the one in the window is between The air space enclosed by the panes is used as a chamber in order to operate in a multi-cycle process to extract heat from the room exhaust air in the chamber, to store it within the chamber, to release them in the next cycle to the fresh air supplied from the outside and in the further Tact to supply the preheated supply air to the room.

The supply and exhaust air is to be transported using interval-controlled Rotary valves in the form of slotted tubes, one of which is in the bottom and one in the bottom is arranged in the upper chamber area, due to the temperature differences of the inlet or exhaust air and the pressure differences between the room and the outside atmosphere the thermo-siphon principle. The intervals that correspond to the cycle times could be correspond to the duration of the heat exchange and the flushing processes in the window chamber according to the prevailing climatic conditions and also to be able to optimize window size and volume dependent.

To support the natural air transport, a integrated #, possibly inside a slotted tube arranged fan with electrical Drive are used.

It can also be optional if the prevailing climates make it advisable make appear one or the other clock with its corresponding slotted tube position are maintained, the exchange of air also being supported by a fan can be.

Thus one has the possibility of a room - aeration and ventilation carry out a longer period of time, although temporarily the heat and soundproofing of the window slightly in favor of the currently desired Function is restricted, the above and below the glazing of the window Slotted tubes arranged in integrated housing parts are preferably packaged in foam embedded to optimize sound insulation.

The slotted tubes essentially have three switching positions: Position 1) Connection chamber to the outside Position 2) Connection chamber to the inside; Position 3) Complete closure The rotary movement of the slotted tubes is shown as an example in a known way with electrically operated servos (switchable small gear motors) carried out. The necessary impulses are provided in an equally well-known manner by a rotating, time-adjustable and adjustable interval generator triggered.

To the heat storage or heat release during the hielWftir provided To favor clocks, the inner fall (leil) ung) of the window sash encompassing Frame on at least two sides, but preferably also on all sides with this lined with suitable material. According to the invention, a metal can be used for this purpose use good thermal conductivity and large surface structure, e.g. 13 on off Aluminum produced in an extrusion process, finely laminated in the axial direction Profile.

Furthermore, it is proposed according to the invention, with several, in one Room located or adjacent, possibly combined in one element Windows to let the cycle sequence for the ventilation take place out of phase. This means that the room air-conditioning is largely continuous.

Ultimately, by means of an interval switch mentioned above, in connection with a timer switch the ventilation for certain operating times or switched off.

If for better air conditioning of the supply air and to promote the Room hygiene humidification of the air is necessary, this can also be done Chamber between the # .panes # of the window.
