FR2492065A1 - Panel-type solar heat collector - has air duct connected to inlet and outlet collector - Google Patents

Abstract

The solar panel is fixed to the purlins (7A,7B) of a rod by angle brackets (8A,8B). The angle brackets (8A) supports the air inlet collector (6A) whilst the other bracket (8B) supports the warm air outlet collector (6B). The metallic air duct is fixed to the inlet and outlet collectors by the liners (5A,5B). A layer of insulation is installed below the air duct and a static layer of air (3) is enclosed between the outer glazing panel (2) and the outer surface of the air duct. This surface is vitreous enamelled in a dark colour.

Description

Device for collecting solar energy
In French patent application No. 80 15 481 filed on July 11, 1980, the Applicants have described a solar air collector and its application to 11 air conditioning equipment of a building.

 In particular, a method of fixing the sensors to a building wall has been specified.

 An object of the present invention is to provide a new arrangement of solar air collectors, in particular for equipping individual houses, for which greater simplicity of implementation is sought.

 the invention relates to a device for collecting solar energy comprising at least one solar air collector, of the type formed by a metal sheath of substantially rectangular section, said sheath having a first and a second open end, the device comprising in addition a cold air intake manifold and an outlet manifold receiving the hot air from the sensor, characterized in that the metal sheath is kept in a fixed position by means of two sheath-shaped seals, a first seal connecting sealingly an opening of the intake manifold and a first open end of the sheath, a second seal sealingly connecting an opening of the outlet manifold and a second end of the sheath, the collectors each being fixed to a structural element of a house.

 The mounting of such a device is simple and does not require attaching to the metal sheath hanging brackets, nor to provide on the walls or frames of additional devices receiving the supports.

 The invention is clarified by the detailed description of an embodiment, made with reference to the accompanying drawing in which - Figure 1 is a vertical section of a roofing element provided with a device according to the invention - Figure 2 is a section on the line II-II in FIG. 1 - FIG. 3 is an enlarged view of part of FIG. 1 - FIG. 4 is an enlarged view of part of FIG. 2.

 In Figure 1, there is a solar collector 1, having the shape of a rectangular parallelepiped, and consisting of two folded sheets and assembled to form a sheath, as has been described in the aforementioned patent application. One of the sheets, which is exposed to the sun's rays, is made of vitreous enamelled steel, dark in color; the other sheet, galvanized, is crimped onto the enamelled sheet. The sensor is arranged so as to fit into a roof and can be tilted relative to the horizontal by an angle ranging from zero degrees (terrace) up to 50 degrees, according to regulatory building regulations.

 Parallel to the plane of the solar collector is arranged a glazing 2 the purpose of which is to delimit, with the collector, an air gap 3 limiting the thermal losses by convection of the surface.

 The sensor 1 is provided on its rear face with an insulating layer 4 which limits the thermal losses of the sensor.

 According to the invention, the sensor is held in place by sleeves 5A and 5B, respectively fixed to a manifold 6A for supplying cold air and to a collector 6B for leaving hot air.

 The sleeves, preferably made of elastomeric material, form seals between the interior of the assembly formed by the sensor and the collectors and the exterior of this assembly.

 The seals are fixed on the respective collectors, then the sensor is threaded on the seals which then suffice to support it.

 Joints from 4 to S cm in length are sufficient to support a sensor having a length of up to 2.5 meters in length (measured between the collectors) with a width of 0.75 meters.

 The fixing of the seal on the manifold is carried out for example by means of screws and nuts. Referring to Figure 3 which shows, enlarged, part C of Figure 1, we see that the manifold 6B is fixed to a fault 7B of the frame by means of an angle 8B.

 The collector 6A is similarly fixed to a purlin 7A.

 The collector 6B is partially surrounded by a layer 9B of thermal insulating material held by a profile 10B fixed to the purlin 7B.

 The collector 6A is similarly insulated.

 Figure 2 shows that one can have side by side several sensors such as sensor 1 of Figure 1. These sensors are referenced 1A, 1B, 1C, 1D. You can have up to 5 sensors with a single input collector and a single output collector.

Figure 4, which shows, enlarged, part D of Figure 2, shows that at the junction between two sensors the thermal insulation It is extended at 14 to the metal frame 12 of the glazing, the space 3 between the glazing 2 and the sensor 1 being closed by a wall 13, fixed on the sensor.

 The invention applies in particular to the heating equipment of individual houses.
