Abstract

The present invention concerns a window unit or french window for the insulation of bay windows forming a heat recuperator and air conditioning device. Window unit or french window characterised in that it is essentially constituted by a fixed sash 1 comprising two door frames 2-3, one of which 2 is intended to be an inside door leaf 4 and the other 3 an outside door leaf 6, of smaller dimensions than the inside door leaf 4, at least one 4 of these doors leaves being fitted with an insulating glazing 5, by a venetian blind 8 disposed between the two door frames 2-3, and by ventilation louvres 9 formed in the door frames 2-3 and which can be independently closed off.

Description

 The present invention relates to the field-closures of the building, in particular windows such as windows and doors-feneAtres, and has for object a block-window or door feneAtre for the insulation of glass windows forming heat recovery and device air conditioning.

 Currently, the closure of such bays is generally provided by means of glazed hunt with or without opening leaves, whose glazing is a double or triple insulating glass, to ensure continuity of insulation with the rest of the wall .

These existing glass frames ensure the thermal and sound insulation of the bays they equip, but do not allow to influence the atmosphere of the local team, for example to provide additional heating or air conditioning.
The present invention aims to overcome these disadvantages.

 It has, in effect, a blockSfenetre or French window for the insulation of glass windows forming heat recovery and air conditioning device, characterized in that it is essentially constituted by a chassies comprising two dormant frames, of which the one is intended for an inner flap, and the other for an outer flapper, of smaller dimensions than the inner flap, at least one of the flaps being provided with an insulating glazing unit, by a slat blind arranged between the two flaps. dormant frames, and by means of closable air vents independently formed in the dormant frames.

 The invention will be better understood thanks to the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the accompanying diagrammatic drawings, in which FIG. sectional view of a window-block or French window according to the invention, and Figures 2 to 5 show views similar to that of Figure 1, on a smaller scale, the operation of the window-block or day and night windows, respectively in winter (Figures 2 and 3) and in summer (Figures 4 and 5).

 According to the invention, and as shown more particularly, by way of example, Figure 1 of the accompanying drawings, the window block or window holder for the insulation of windows forming heat recovery and air conditioning device is constituted by a chassies I comprising two dormant frames 2 and 3, whose inner frame 2 is intended for a leaf 4 with insulating glazing 5 and the outer frame 3 with a leaf 6 with single glazing 7, by a lamella blind 8 mounted between the frames 2 and 3, and by vents 9 closable independently of each other, and arranged, preferably, in the upper and lower rails frames 2 and 3.

 It is also possible to equip the outer flap 6 with an insulating glazing, the inner flap 4 then being provided with a single glazing, or insulating, but at least one of the two flaps is provided with such an insulating glazing unit. .

 The outer flap 6 advantageously has dimensions smaller than those of the inner flap 4 so as to allow its complete opening.

 In order to allow a perfect disengagement of the air vents 9, the inner frame 2 is provided, below its upper rail and above its lower rail, with retaining rails 10, which limit the travel of the slats of the blind. 8 up and down. Thus, in the open position, the blind 8 is held against the upper rail 10 and hidden by the cross members of the frame 2 --- and the leaf 4 (Figures 3 and 5), and in the service position, the lower part of the blind 8 rests on the lower rail 10.

 The blind 8 is advantageously constituted by lamellae having an absorption face forming a solar energy sensor, and a reflecting surface reflecting the sun's rays through the glazing of the outer wing 6. It is also possible to make these strips with a parabolic section, their inner face being reflective and concentrating solar radiation on a thin zone of the outer face of the previous lamella, which is an absorption face. With this embodiment, the temperature gradient is high and allows a good thermal efficiency.

 The air vents 9 are of known type and can be controlled by means of actuating buttons 11, or in any other way.

 As described above, the ears 9 are preferably provided in the upper and lower rails of the sleeping frames 2 and 3. However, these ears may also be provided in the uprights of these frames, and their shape may be arbitrary.

 Thanks to its constitution, the device according to the invention can provide in addition to its insulating closure function, a heat recovery function, and a cooling function by aeration.

 Figures 2 and 3 show the operation of the window block or door-window in winter, respectively day with sunshine and night. Thus, by day, the blind 8 is advantageously lowered with its slats in an oblique position, in the direction of the sun, so as to form a solar collector whose space between the glazing 7 of the outer flap 6 and the blind 8 is swept by a penetrating air flow through the orles 9 of the lower cross member of the inner frame 2 and exiting heated by the orles 9 of the upper cross member of said frame 2. At night, the closing of the orles 9 allows for a sealed enclosure, wherein is enclosed a stationary air mass promoting thermal insulation.

 The operation of the block according to the invention in summer is shown in FIG. 4 and 5. By day and by sunshine, the blind 8 is lowered, its slats being in an oblique position so as to present their reflecting face to the sun's rays. in order to achieve attenuation of their effect by reflection of said rays, and aeration ale 9 of the sleepers of the outer frame frame 3 are open. The air between the frames 2 and 3 is then continuously renewed without risking intense heating, and the thermal insulation is improved. At night (FIG. 5), all the rings 9 are open, so that the hot air of the room can escape in the upper part of the block, a supplement of fresh air being able to penetrate through the lower ones.

 According to an alternative embodiment of the invention, not shown in the accompanying drawings, the window block or window can be provided with a heating element integrated in the frame 1 between the dormant frames 2 and 3, preferably between their lower cross member, and ensuring in the space between said frames air blade temperature greater than that of the outside and lower than the room.

 The heating element may be constituted by a low power electrical resistance, advantageously provided with a thermostat, or a small section branch branched line on the. valve of a central heating radiator, or the like.

 Such an embodiment makes it possible to further improve the insulating capacity of the assembly by sup pression of the convective losses, the heating element achieving a temperature corresponding partially to that obtained during the day thanks to the sunshine of the elements. slats of the blind 8.

 According to another embodiment of the invention, the window block or window-holder may be provided with a refrigerating body, at temperature adjustable by thex-mostat, arranged between the dormant frames 2 and 3, preferably in the part upper frame 1, and which ensures in the interior space of the latter an air gap temperature lower than that of the outside and greater than that of the room. Thus, the air of the room does not risk a convection heating by the outside air, and, in addition, it is thus possible to achieve air conditioning of the premises.

 The invention has been described with regard to casement frames. However, it is also applicable in the case of tilt-and-turn frames or sliding frames, or any other -closure closure devices.

 Thanks to the invention, it is possible to produce a window block or window holder for closing bays allowing, in addition to thermal insulation of said bays, a heat recovery during a sunny winter period, and an air conditioning system. by aeration during the summer night period.

 Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications are possible, particularly from the point of view of the constitution of the various elements, or by substitution of technical equivalents, without departing from the scope of protection of the invention.
