Definitions
- the present invention comprises a unit for heating drinking water for domestic consumption, or drinking water for industrial use, using solar energy.
- the unit can be applied mainly based on the natural convection circulation of the fluid, called thermosiphon circulation, although forced circulation is also feasible;
- thermosiphon circulation although forced circulation is also feasible;
- This unit is low cost, low maintenance and long service life, all these features combined with high efficiency, which allows compact and easy to install units, and can be applied directly to pressurized sanitary water networks.
- the temperatures involved in the applications described include water for sanitary or recreational use in homes and sanitary use in industry.
- the low cost of the units of the present invention is based on the efficient use of polymeric materials together with high-performance industrial manufacturing processes. Consequently, the circulation of the fluid is carried out in an exchanger made of polymeric material.
- the low maintenance of the units is achieved by the non-stick characteristics of polymers in general, and of the polymer in particular used in the present invention, which in general have a coefficient of thermal expansion different from that of the elements that tend to precipitate and adhere on the internal surfaces of the exchanger, which translates into a low tendency to generate scale and scale, especially in regions where available water has a large amount of diluted and suspended salts.
- the mechanical resistance of the exchanger is suitable for high i applications pressure, that is, to be directly connected to domestic sanitary water networks or sanitary water or industrial fluid networks.
- the mechanical resistance includes an adequate capacity that considers the freezing of the fluid inside the exchanger, especially when the fluid is water or some similar fluid that increases its volume when it is frozen, a situation that is quite likely because the units are located Outdoor for operation.
- the exchangers of the units of the state of the art must include, within certain operating periods, deep cleaning of the circuit that forces their partial or complete dismantling. This generates high maintenance costs, especially if it is considered that the units must be installed in places of difficult access such as terraces and roofs.
- Document CH621622 discloses a system for connecting a series of branch pipes to a common inlet so as to form an exchanger.
- the main deference between what is disclosed in the cited document and the present invention lies in the composition of the junctions of the bypass tube and the parallel tubes.
- the document discloses mechanical unions composed of three independent elements that allow the configuration of an exchange circuit. The provision of three elements are maintained by mechanical interference, which does not allow to ensure operation under conditions of internal fluid pressure, due to the risk of leaks. Mechanical interference is based on the use of elastic stress on the components during assembly. This elastic effort can be lost during the service of the union and the exposure of the material to heat and solar radiation.
- the exchanger of the present invention is obtained by the arrangement of two elements: manifold and tubes, joined by a thermofusion process, which establishes a molecular junction of the thermoplastic of the same type and quality as that found in the very material of the constituent parts. With this solution the leaks are discarded because it is a single internal circuit, which is empowered to operate at high pressure, allowing its direct connection to sanitary networks.
- CA1291474 Another state-of-the-art document that discloses details of the connection of the bypass tube to parallel tubes is CA1291474.
- the disclosed elements have a coil consisting of a pipe in whose cross section it is possible to distinguish different rings of material (metal, rubber and plastic), allowing to reach various applications, being raised mainly as an element that requires exchanging heat from a primary source to a high school for her application.
- This explains the arrangement of the pipes which obey the logic of the distribution of a radiator, where what is sought is to generate a circuit that is capable of distributing the heat dissipated by the tubes as homogeneously as possible, considering the existence of a booster pump and a closed circuit.
- the arrangement of the disclosed closed circuit allows it to incorporate special additives into the fluid, providing good performance over time; This differentiates it markedly from the system of the invention under study, which is designed to dispense with the secondary circuit and additional components, allowing the operation of the system with drinking water inside, favoring a configuration that allows greater solar collection minimizing Loss of energy Additionally, the arrangement and composition of the present invention, with pipes in parallel, allows the upstream operation of the internal water allowing operation by thermosiphon.
- GB2445222 discloses a system that allows you to configure sun catcher covers, without the need to install solar panels as extra elements in the configuration of the house.
- the modules are internally composed of a series of copper tubes, which are welded with copper fins solar collectors, these are arranged covering the largest area of desolation and a provision that allows the assembly of these on the roof of the buildings.
- the roof of these tiles is made of plastic material. The arrangement does not allow the operation of the modules by thermosiphon and requires the provision of a secondary circuit that contributes to a heat exchanger, commanded by a pump that allows the movement of the fluid.
- the product seeks to solve the architectural integration of solar panels, opting to cover a large collection area, rather than making the use of solar energy efficient in a system.
- the system of the present invention is configured to obtain the maximum yields, with the simplest possible system, avoiding secondary heat exchangers and complex circuits, in such a way as to favor the simple operation of the system which can be directly connected. to the home network.
- Another document of the state of the art, oriented mainly to constructive elements of the box corresponds to DE10321422.
- This document discloses the junctions of the receiver box of the heat exchanger of a solar panel type; the document establishes the provision of an angular piece that allows mechanically fix the lateral profiles of the box; In addition, an upper flange is established that allows a second piece to be fitted that by pressure supports the translucent cover.
- the box set forth in the cited document is due to a design of a rigid structuring frame for the arrangement of a solar panel inside;
- the model developed in the present invention raises a box to obtain the highest performance according to the collector inserted inside, that is, it is an integral part of the design of the collector in order to achieve optimum performance and the operating characteristics described in the previous paragraphs.
- Figure 1 shows a three-dimensional view of the unit for heating drinking water for domestic consumption, or drinking water for industrial use, using solar energy.
- a part of the translucent panel has been removed to show the arrangement of the parallel tubes.
- Figure 2 shows a cross-sectional view of the unit for heating drinking water.
- the profiles that make up the box, the insulating material and the arrangement of parallel tubes with respect to the translucent lid can be seen.
- the area that will be shown in detail in the following figure is enclosed in a circle.
- FIG 4 a sectional view of the distribution and collection tubes attached to the parallel tubes can be seen.
- the figure shows how two units of which are required to form the water circuit of an exchange unit of the preferred embodiment of the present invention are interconnected.
- the connection between the distribution tubes is made by thermofusion and the connection of the parallel tubes is made by thermofusion in the preferred mode, although in an alternative mode they can be connected by interference.
- connection scheme of a collection unit can be seen in one of the most efficient ways and which takes advantage of the main advantages of the present invention.
- the connection is direct to the sanitary water network and the circulation between the thermos and the collection unit is by thermosiphon effect, in this way no moving parts are required, the only restriction being the relative location of the thermos with respect to the collecting unit , which must be located above the collection unit.
- FIG 7 a graph of standard tests carried out in the collecting unit is shown where you can see the efficiency in the vertical axis, with respect to the difference between the ambient temperature and the average temperature normalized by the irradiation that normally affects the surface of the collecting unit.
- the vertical axis corresponds to efficiency and the horizontal axis corresponds to (T m - T a ) / I, where T m corresponds to the average water temperature, T a corresponds to the ambient temperature e / corresponds to the solar power per meter square that normally affects the collecting unit.
- Figure 7 shows a curve that only it is slightly more vertical than an equivalent curve of a conventional copper tube collecting unit, which is equivalent to a slightly more marked sensitivity to increases in the difference between the average temperature and the ambient temperature. It implies that in applications where hot water is required for home and recreational use, such as in swimming pools and bathrooms, the efficiency is absolutely comparable with conventional collection units, since excessively high temperatures are not required.
- the present invention corresponds to a solar energy collecting unit for heating water in high pressure applications and in which the circuit may be exposed to freezing temperatures.

- the solar energy collecting unit to heat water uses thermofusion joints, which guarantees a union without contribution or contamination, where the properties of the material remain unchanged and finally a single component final piece is obtained where the macromolecule of Plastic is rebuilt and the union is not distinguished.
- the parallel tubes (1) are manufactured by extrusion molding and are of substantially regular section. This is a common way of manufacturing large volumes of regular section tubes in a homogeneous, efficient and regular quality manner, suitable for the high mechanical demands that the high relative temperatures and the stresses that are imposed on the material by the freezing of the liquid in the lumen of the tubes.
- This process also allows the parallel tubes (1) to be cut to a standardized measure and their ends prepared for the process of joining the tubes of bypass (2) and discharge (3) by thermo fusion. In this way, collection and discharge units of lengths suitable for particular projects can be provided, although standardized measures are preferable in order to produce similar low-cost units.

- the efficiency of the collecting unit of the present invention in its preferred embodiment has been extensively evaluated and is comparable with the efficiency of the state of the art for the collection units manufactured in conventional materials.
