FR2500133A1 - Controlled solar heating of air circulated through enclosed space - with facility to cool space by exhausting circulated air to atmos. - Google Patents

Abstract

A current of air is drawn from the space. If the space requires heating the air current is warmed by solar radiation and returned to the space. If the space requires cooling, the air current is exhausted to atmos. and make-up air allowed to enter the space through low-level grills. Solar radiation through the glazed wall of a shaft contg. a multi-slatted venetian blind through which the air current has to pass. The slats pick up solar heat which is transferred to the air current. Pref. a fan is employed to force the air current of the shaft. The installation could provide winter heating and summer cooling for dwellings, factories, greenhouses, etc. and coul provide heat for crop driers and fruit driers. The installation is simple and inexpensive to install and operate.

Description

 The present invention relates to a forced air conditioning apparatus by solar radiator allowing in winter a heating, in summer a ventilation, intended for individual or collective houses, as well as for various industrial uses.

 In known devices of this kind, the problem of storage which is difficult to solve is very generally inapplicable to existing constructions. In addition, particularly special conditions for installing the devices known to date require studies for the installation of the material on the structure.

 The operation of the system of the present invention proves to be very flexible and reliable and does not require large investments by using standard commercial products. The device composed of a cold room and a hot room creates a forced depression. In addition, the addition of non-return valves automatically isolates the device from the room to be heated in the event of an anomaly or insufficient solar energy supply. This device has the advantage of not necessarily having to be close to the room to be heated, during installation constraints, by using suction and blowing ducts to be incorporated into the building or not.

 The device, object of the invention according to FIG. 1, comprises louvers 1 and 2 of small thickness comprising blades, advantageously using, for example, standard commercial shutters, the whole mounted on a frame allowing the air to pass and therefore playing the role of solar radiator. Double glazing, 3 and 4 on the external face, the internal face being covered with an insulating panel 13, such as for example hard and smooth hardboard or any other material giving the same results. An orifice, 17, allows any condensation water to be evacuated, situated in such a way that there is no source of introduction of outside air.

 This arrangement consists of forming a cold room, 5, and a hot room, 6, all inserted in a frame, 7, which can be easily affixed or integrated into a construction.

 A motor-fan, 8, draws air from the room and discharges it through an orifice, 9, crossing the wall. Likewise, the orifice, 10, passing through the wall allows the hot air to be distributed either directly in the room or by means of a pipe, 20, in the neighboring rooms, the return of cold air. then done by grids placed at the bottom of the doors.

 The air inlet box, 15, comprises a flow regulator 16, with a non-return valve. Likewise, the outlet box, 10, is equipped with a non-return valve 11. These valves are advantageously standard, such as for example the brand "Moderator".

 The temperature of the heated volume is regulated by the room thermostat 18, which acts on the fan motor 8. The installation is started up by a switch.

 A thermostat 12, also acts on the motor-fan, 8, so that the air distributed is sufficiently hot. A thermometer 14, gives the indication of the temperature prevailing in the hot room, 6.

 In summer period, the hot air is discharged outside through the conduit 21, after removing the pad 22, and closed the box 10, by the plate 19. An air intake located on a cold wall of the local will be practiced.

 The device which is the subject of the invention can be installed easily without major adaptation costs and applies without the list being limiting to dwellings and other premises such as: workshops, depots, agricultural sheds, gardening greenhouses, drying racks. linen, hay, prunes, medicinal plants, flower pollen, etc. or any other manufacturing or transformation process requiring a hot air flow.

Claims (6)

1) Air conditioning device for forced air intended for heating and  ventilation during the hot period, by solar radiator, characterized  in that the solar flux is absorbed by a set of louvers (1)  and (2), the air circulation system is provided by ventilation  forced (8) or natural, further comprising thermal regulation,  usable either in an adjoining room or in a remote room. 2) Device according to claim 1, characterized in that the installation  a fan motor (8) allows better temperature regulation  ture and better heat exchange. 3) regulation assembly according to claims 1 and 2 characterized in that  that it has non-return valves and an adjustable flow rate (16) and (11). 4) Device according to claims 1, 2 and 3 characterized in that the  thermal regulation is ensured by thermostats (18)  and (12) eliminating any risk of introducing insufficiently hot air. 5) Device according to claims 1, 2 and 3 characterized in that the air  hot is directly usable in a more distant room by user  tion of a pipe (20) insulated or not, depending on the environment. 6) Device according to claims 1 and 2 characterized in that it  comprises a closure of the box (10) and a conduit (21) on which  a shutter (22) is provided for use in ventilation  of the room in summer by extracting air by the motor-fan (8) and  rejection of outside air.
