Description

AIR-WATER SOLAR WATER HEATER.

The present invention relates to a solar water heater device called "Air-Water", compact, compact and weight, usable in all climates and without any contribution of antifreeze or other products incompatible with the environment, characterized in that '' it combines two functionalities: a first so-called primary circuit functionality, consisting in capturing the calories from an air circuit heated by solar radiation and a second so-called secondary circuit functionality for moving the water heated by the calories captured by the primary circuit, using the thermosiphon phenomenon. Without apparent water reserves, the device of the invention is preferably in the form of a block of two successive flat panels of small thickness, including a first main plane preferably of rectangular parallelepiped shape comprising the device for capturing solar rays, for heating and circulating water, and a second annex plan of much smaller surface extending the main plane to contain the air suction device and the regulation means.

The device uses automatic regulation by a set of judiciously placed probes which as soon as the difference in water temperature between the two reserves (upper and lower) reaches one or more previously programmed values, automatically starts the production of a carpet air circulating on a heat absorbing plane, under the effect of an injection rail and a suction device causing a circulation of hot air in a closed circuit.

Numerous means are known today for heating heat-transfer products and more generally liquids by solar exposure, to transmit the calories taken by these products to domestic liquids and in particular to the water used by most homes.

If the removal of the heat given off by the sun's rays is now known to all and applied without great difficulty, certain parameters still remain to be mastered to make this mode reliable, economical and ecological.

Among these parameters, that of the imbalance between the optimum moment of production of solar heat and the moment of consumption, inevitably leads to the storage of hot water and above all to maintain it at operating temperature during unproductive periods and periods of inactivity.

To be reliable, efficient and economical, installations using solar radiation cannot multiply the use of overly bulky or too expensive ancillary equipment such as pumps, valves, diverter etc.

This is why, the thermosyphon phenomenon based on the difference in density between cold and hot water is often used to ensure the circulation of water in certain circuits. Thus the warmed cold water rises naturally from a sensor placed in the lower part towards a balloon most often placed at a level higher than that of the sensor, thus generating a natural circulation, entirely autonomous without circulation device or regulator and totally static. .

Most of the existing devices such as that described in US Pat. No. 4,766,650 state the installation of solar water heaters with solar collectors, heat exchangers, connection to a tank and circulation by thermosyphon phenomenon.

If this type of installation is effectively effective in applications in hot regions, it requires in colder or temperate regions the addition of antifreeze functionality.

It is also known for many installations, implementation problems, the collectors generally of flat shape being designed to be most often placed on roofs in order to obtain a better capture of the solar rays, must imperatively be placed on a plan much lower than that of the storage tanks, which obviously complicates things at the technical level because the supports must be reinforced, as well as at the level of aesthetics in an urban environment.

The use of these installations also involves securing the installed equipment, which, most often placed on the roofs, is exposed to bad weather, gusts of wind and other storms which place a heavy test on the equipment and its supports.

Aware of the drawbacks of the installations currently used in our environment, the author of the present invention has imagined a solar water heater device making it possible to reduce the size and the weight of the equipment while significantly improving performance.

Advantageously, the device of the invention is optimized by the use of sensors of suitable shape, as well as a particular technical arrangement associating circulation of air and circulation of water.

Air-Eau solar water heater according to claims 1, 3, 5 and 8, characterized in that 1 '"annex enclosure" (200), accessible by simple tilting of the "annex solar plan" (201), comprises its interior the "turbine group" (112), the connection of said "turbine group" (112) with the "warming chamber" (110) or the "suction tube" (111), the connection of said "turbine group" (112 ) with the “injection rail” (114) or the “delivery tube” (122), an electrical means for assisting with heating known as “support resistance” (207) provided with its thermal probe called “resistance probe” (209), the cold water inlet and hot water outlet conduits and an automatic regulation device called "regulator" (210) allowing the "turbine group" (112) to be triggered according to the temperature information from at least two thermal probes, in particular a so-called “air intake probe” (206) placed at the outlet from the “heating chamber” (110) on the “suction tube” (111) for access to the “turbine group” (112) and a probe called “high probe” (208) placed at the level of the “separator "(121) of the" warm air ramp "(113). 10, - Air-Eau solar water heater according to claims 1, 3, 5, 8 and 9, characterized in that 1 "annex enclosure" (200), includes the hydraulic and electrical arrangements necessary for the twinning of the water heater Air-Eau of the invention with other identical equipment, whatever the side of said pairing, the technical design of the equipment being adapted to the possible twinning of the two sides of the "annex enclosure" (200), the unused side being provided with shutters.
