Description

SOLAR HEATING SYSTEM FOR SWIMMING POOLS Field of the invention The present invention relates generally to swimming pool heaters and more specifically relates to a solar heating system for efficiently heating a pool with solar energy.

Background Pool heaters have been used for many years. One type of these heaters is one that comprises an electric unit as a heater that heats the water using a conventional power source. A second type of pool heater comprises a cover that allows solar energy to enter the pool but retains solar energy within it. Another type of pool heater is one that comprises a solar heating unit that is positioned away from the pool where the water is pumped to the solar heating unit and when the water is hot it is returned to the pool.

One of these types of heaters is that described in US Patent 5,012,796 which consists of a manifold comprising a system of conduits for fluids connected to a pair of solar heaters.

Also, in the patent ES 1, 005.91 1 a pool heating system is described, which basically comprises a unit of solar cells that are responsible for transmitting solar energy to water.

Another type of pool heaters is that described in the US patent. 5,347,984, which consists of a sheet of flexible corrugated plastic that has one side of the sheet matte black and the other side in white, in addition to a flotation system based on plastic tubes located at the ends of the sheet .

The patent US 6,508,247 also describes a heater very similar to that of the previous patent; In this case, solar panels are described, which are rectangular or circular, black, plastic, floatable, corrugated, connectable and roll-up that cover the pool when it is not used.

US Patent 5,347,984 discloses a solar heater for pools based on flexible corrugated sheets having one side matte black and the other white, which is the one that is suspended below the surface of the water in a pool using floats tubular plastics and a series of staples. During daylight hours, the leaf is placed with the dark surface up and in reverse during the night to minimize heat loss.

US Pat. No. 5,143,052 describes a floating solar pool heater consisting of a plurality of vinyl tubes accommodated in multiple variations including the parallel position, together or separately, or in a coil pattern in such a way as to allow the water from the pool flow through it. The tubes can be transparent with a dark ribbon inside the portions of the base. A piping system in the form of an air bag can be included to collect heat.

US Patent 3,076,450 discloses a plastic swimming pool heater comprising a rectangular plastic frame having a transparent cover, an air space on a transparent panel covering a line of pipe in the form of a coil with a black plastic layer on the opposite side at the end of the ducts, and a layer of polyurethane foam forming the open base. The apparatus is distinguished by requiring a flotation foam and a water flow system in the form of a coil.

US 3,022,781 discloses a collapsible solar pool heat collector made of two flexible plastic membranes arranged as a coil or in the form of a pair of frames with a plurality of fluid conduits having inlet and outlet tubes. The rectangular frame is made from wood. The plastic film can be made of polyethylene, vinyl, polytetrafluoroethylene or polychlorotriflouretylene. Both the upper and lower plastic layer are painted black or have black carbon incorporated in the plastic.

US Pat. No. 3,683,428 discloses a rigid, floating, insulating and rapidly folding pool cover comprising foam sheets joined by flexible hinges.

However, conventional pool heaters have several drawbacks; to mention a few, many of them use a heating system by boilers that turns out to be very expensive, others use a solar concentration system from solar cells which have the disadvantage of heating water only superficial level, and some more are inefficient to heat different sizes and shapes of pools.

In this sense, the solar heating system for swimming pools of the present invention substantially overcomes the drawbacks of the conventional concepts and designs of the prior art, and thus provides a system developed for the purpose of efficiently heating the water of a pool using solar energy Object of the invention One purpose of the present invention is to provide a method of heating the water of a pool using solar energy.

Another object of the present invention is to provide a water heating system for a swimming pool.

Still, another object of the present invention is to provide a pool heating system that can be used in various sizes and shapes of pools.

Still, another object of the present invention is to provide a pool heating system which does not require additional space other than the pool.

Other objects and advantages of the present invention will be obvious to the reader and such objects and advantages are within the scope of the present invention.

To complement the objects indicated above, this invention can be understood in the illustrated form of the accompanying figure; However, this figure is merely illustrative, and any type of Changes in the specific construction illustrated and described will be within the scope of the claims claimed.

Brief description of the figures Figure 1 is a perspective view of the solar heating system for swimming pools, where (1) is an electric pump that has the function of raising the water of the pool to a coil system placed on the roof of a building, ( 2) is a pipe system that conducts water from the pool to the coil system, (3) it is a coil system where water heating is carried out through the absorption of solar energy, (4) is a pipe system that conducts the heated water in the coil system to the pool, and (5) is the pool.

Description of the invention The present invention provides a solar swimming pool heating system, which comprises an electric pump, an inlet pipe system that leads water from the pool to the coil system, a dark flexible plastic pipe system in the form of an elliptical coil , and a pipe system that conducts water from the coil system to the pool.

The electric pump is of a conventional design and has the function of pumping the water from the pool into the inlet pipe system, which It is directly connected to a coil system made of dark flexible plastic, usually black, of a caliber selected from the range of one half to three quarters of an inch. In this coil system where water heating takes place by using solar energy, since being a black surface allows the absorption of infrared rays from the sun and thus heats the water placed inside the system of plastic tubes that comprise the coil. It should be noted that the coil system has a length that allows sufficient water inside to fill the pool. In turn, the coil system is connected to an outlet pipe system that carries water from the coil system to the pool. In this sense, part of the pipe system, as well as the inlet pipe system may be located on the ground surface, or underground.

The coil system is made of a flexible polymer plastic material selected from the group of vinyl, polyvinyl chloride, polyethylene, polypropylene, polytetrafluoroethylene, polychlorotrifluoroethylene, and styrene. Vinyl plastic is preferred for resisting the deteriorating effect of ultraviolet light.

The exposure time of the water inside the coil to the solar rays will vary in time according to the volume of the pool. Additionally, in climates where water could freeze, the system may contain a series of valves that will allow to drain the water contained within the coil system.

It should also be understood that multiple changes and modifications may be made to the present invention, which will not be beyond the scope of the invention or the spirit of the invention.
