FR2493391A1 - Ventilation unit for solar ray collecting window - has ducted surround with valves distributing warm air captured by shutters - Google Patents

Abstract

The window has single or double glazing (1) and behind that are blinds or shutters (4) that act as solar captors as well as providing a high insulation and an air tight seal. A box surrounds the shutters and has a lower air intake (5), an inversion shutter that can be worked manually or electro mechanically, and a non return valve (3). The outside facing surface of the shutter (6) has a selective dressing of high absorption and can be arranged with some channels or eyelets or it can be placed behind an assembly of adjustable blades.

Description

The present invention relates to openings, windows or bays, specially arranged to provide thermal gain using energy ~ olai- re. It is intended for the equipment of buildings, dwellings, offices, factories, etc ...

To date, the openings of the houses allow direct solar gains with glazing without shutter or curtain, or these being open. This gain is removed from the firm component.

These openings allow, at night, a significant loss of calories, as well as overheating of the house, the summer. When we want to carry out solar heating, we have either a greenhouse that is difficult to control, or a dark wall (wall
Tornado, or sensor).

In most cases, no burglary security is provided.

The present embodiment allows these windows and windows to perform the following functions:
A - direct sunshine with room lighting and light control
B - burglar-resistant closures or shutters
C - closures or insulating shutters (for nights)
D - air sensor operation, closings in place (on sunny days) Z - automatic shutter (at night) of the air passage
F - reverse air at sensor outlet s
1) inward (winter)
2) outwards (summer)
Windows or bay windows (opening or fixed), single or double glazing, are internally supplemented by an insulating shutter, either foldable, or with slats (horizontal or vertical), # either with sliding curtain or with rolling positioned a few centimeters to the 'interior of windows; these windows are therefore composed of a glazed surface and a movable insulating wall, the front face of which is arranged to capture the maximum of solar rays.

The whole being included in a frame comprising air inlets at the bottom, air outlets at the top, in a special box. This box includes hot air outlets to the interior with very sensitive automatic valves preventing cold air from entering at night. It also includes winter-summer reversal flaps ensuring the diffusion of hot air in winter towards the house, through valves; in summer, direct heat dissipation to the outside with circulation of fresh air in the house.

The sealing device is provided with very insulating, waterproof and anti-breakage properties. It is made up either of insulating curtains, or of classic shutters or of sunshade shutters with vertical or horizontal slats, mounted fixed and swiveling or pivoting and retractable.

The window or opening must meet the characteristics of the general drawing (fig.l P1.1), window 1, reversing shutters 2, automatic shutters 3, sunshade shutters or insulating curtains 4, lower air intakes 5, selective surface 6 .

 The insulator operating in direct gain fig.2 as a sensor, with anti-intrusion security fig.3, in insulation fig.4, in anti-overheating device fig.5.

The upper distribution box is made of insulating or insulated dobby.

It includes a very sensitive non-return valve 3 (P1.2 fig.l) and an interior-exterior reversal flap 2 (P1.2 fig.i) with manual or electro-mechanical co-controls. The main shutters which can take the form of flexible composite curtains, folding shutters 4 (fig.2 P1.2) or sunblinds with fixed axis and controlled rotation (fig.3 P1.2). Channel 7 (fig. 3
P1.2) ensures the connection between axes by means of pinions 8 (fig.3 P1.2) and the tensioners 9 (fig.3 P1.2), a latch 10 (fig.3 Pl.2) immobilizes the blades.

This rotation can also be obtained by rods or racks.

These sunshades can be mounted retractable with a movable axis and controlled rotation (fig. 4 P1.2), the blocks 11 (fig. 4 P1.2) made of anti-friction material sliding in the profile 12 (fig. 4 P1.2) by a screw 13 (fig.4 P1.2) and the interval pins 14 (fig.4 P1.2) coma nued by catne and gear motor 15 (fig.4 P1.2). Their spring 16 (fig.4 P1.2) tending to put the blades perpendicular to the glazing, stops of different heights 17 (fig.4 P1.2) provide orientation and closing at the end of the stroke.

 According to another embodiment, behind the window (s) 1 (fig. 1 P1.3), a blind with slats which can be reversible, a sensor side, a reflector side, 18 (fig. 1 Pl.3), is doubled '' a flexible insulating curtain 19 (fig.1 P1.3), or a clear, tinted, reflecting glass or a reversible dark sensor / reflector surface.

The blind can be replaced by a wire mesh or expanded metal 20 (fig.2 P1.3).

Fixed supporting posts can be used 21 (fig.3 P1.3) metallic or not, hollow or filled with concrete or water with circulation, etc ...

The rear surface 22 can be dark or transparent, fixed or mobile.

These bays and windows are intended to equip solar houses.

Claims (9)
