FR2712671A1 - Solar panel for heating swimming pool water - Google Patents

Abstract

The solar panel, using a 'greenhouse effect', consists of a stainless steel panel through which the water runs in a thin layer between inlet and outlet pipes, mounted on an anodised aluminium frame, and covered with a sheet of safety glass. A number of the panels can be set side by side close to ground level for ease of cleaning and maintenance, and they can be connected in parallel to heat the water to the required temperature. The panels can be used to produce hot water for other purposes than swimming pools.

Description

The present invention relates to the manufacture of a solar collector with "greenhouse effect", known per se, intended in particular for heating swimming pool water and competing in performance and resistance with the heat pumps generally chosen for this application. of heating. (Fig. 1)
In this construction, the heating element, of the water-line type, is made from stainless steel sheet of good quality grade 316 L, which allows it to be insensitive to the attack of chlorine which is usually found. in significant quantities, often often unimportant, in swimming pool waters.

 This element which is currently on the market in various constructions and sizes is used for purposes other than capturing solar energy. They are in fact intended to heat or cool baths of different more or less corrosive liquids such as - baths used in electrolysis, dairy, vinegar, etc., in which they are immersed and inside which they circulate: hot water, cold water or other liquids to achieve the same result.

 The heating plate thus produced is insensitive to the attacks of water from pists changed from chlorine and other treatment products such as oxygen products, anti-algae products and pH control products. unlike solar collectors manufactured to produce sanitary hot water, the heating element of which is made from copper which does not resist water charged with chlorine and which therefore cannot be used for heating swimming pools.

 Likewise, the chassis is made up of profiles and anodized aluminum plates of grade AG 06, the sealing of which is ensured by the interposition, between the constituent elements, during the assembly of silicone sealant, thus making it perfect. - resistant to attack by atmospheric agents: rain, sun, mold, moss, etc.

In the search for quality, the glazing is made of safety glass which provides increased resistance to shocks, both thermal and mechanical and total safety in the event of breakage. (Fragmentation of the glass eliminates any risk of serious cutting) since these sensors are , on the designer's recommendation, to be installed at ground level and inclined at about 455 towards the south. This bump installation makes it easy to keep the glazing clean, guaranteeing maximum performance from the device, a port, and to verify, by the simple touch with the hand, of in tr in and exits of the pipes of circulation of water in the collectors, that these work correctly, on the other hand. (Fig. 2)
These solar collectors, which are modular, include upper and lower fixing means which allow them to be assembled and aligned, one after the other. rigidly, the number of which will be defined according to a ratio established by the manufacturer between the surface of a sensor and the volute of water contained in the swimming pool to be heated, variable according to geogrophic situations and therefore the corresponding sunshine values.

 Note that it is possible to install several rows of copters, porallelement, of sufficient spacing, each time the length of the ground available, does not allow to obtain the desired power on a single gnaw.

 These solar collectors thus produced can obviously also be used successfully. in the production of domestic hot water, heating greenhouses, etc., just as they can also be installed high up, such as on roofs, terraces. or various media.

Claims (3)

 1 - Solar collector with "greenhouse effect" intended to heat swimming pool water, not sensitive to different treatment products and noted the chlorine contained in them, including the heating element of the water blade type, is made from a quality 316 L stainless steel panel, preferably existing on the market, but used in different industries as a bath cooler or reheater with various aggressiveness and not previously used as an energy recuperator solar.  2 - Solar collector whose frame and glazing are made from noble materials (anodized aluminum, "safety glass") offering the guarantee of lasting resistance to attack by atmospheric agents (rain, cold, sun, mold, foam, etc.) and intended to be installed, in most cases, at ground level, facilitating growth - monitoring and maintenance (cleaning), including the upper and lower connection systems, allow assembly in line, so rigid, of several sensors placed end to end, the number of which will depend on the desired calorific power.  Several rows of collectors, of sufficient spacing, in order to ensure correct sunshine of the assembly, can be installed in parallel, in case the available length of land does not allow the necessary energy to be obtained with a single row .  3 - Solar collectors which can be advantageously used in any production of hot water, other than that of swimming pools.
