Description

Flat thermodynamic solar collector.

Object of the invention

The present invention refers to a solar panel whose purpose is to capture both radiation solar, either direct or diffuse, as of environmental energy, for the obtaining hot water, presenting a great efficiency to the being able to work even on cold or cloudy days and in total absence of light, such as during the night, with a low electrical consumption

Field of the Invention

This invention falls within the field of alternative energies in general, having their application within of manufacturing products for energy use solar and that contained in the environment in the form of temperature.

Background of the invention

They are well known, in the current state of technique, flat solar collectors that are based on circulate a working fluid through a circuit like water, glycol or a mixture of both, among others, that will leave heating as it runs through it due to the transformation in heat of the solar radiation incident on the surface of the same, reaction that is favored by the greenhouse effect that It originates inside.

On cold or cloudy days it happens that the temperature reached by the collector can be the same or slightly lower than the fluid that circulates inside, and as there is so little or no temperature difference between the two, no major heat transfer will take place, so The team will not work properly.

Likewise, if the heat requirement is Performs at night, no solar panel known in the current state of the art, for its dependent operation of light and solar radiation, would be able to provide a single calorie to the heating system or sanitary hot water that usually goes connected.

The present invention is designed to avoid such events, because it will circulate a fluid inside coolant at its boiling temperature, being able to reach this temperature at values greater than -30º being the difference of temperature between it and the environment quite considerable, running at peak performance when solar radiation strikes about our collector just like conventional collectors, but when there is no sun, or on cloudy days and at night, when the others stop working or work under minimum, our collector will continue to operate with a high coefficient of electrical transformation (COP) by capturing all the calories in your environment, which translates into efficient water collection Hot anytime of the year.

In this way, we obtain a sensor to high efficiency solar and energy use by providing hot water with low energy consumption, which may be used as domestic hot water, or for heating or pool air conditioning or for any other application in the that it is necessary to heat water, air or any other material, and that It works optimally with sunshine and remains a great Effectiveness in your absence.

Description of the invention

Specifically the present invention proposes use a variable size plate according to the application and power to be used, consisting of two aluminum, copper panels or other electro-welded material, in whose interior a die cut or insufflated circuit is delimited, by which refrigerant gas will circulate. This plate will be mounted on a frame of aluminum or other material that will incorporate a solar crystal for its front or sun exposure, which should have as main characteristic a high transmissivity to the solar radiation on its outer face and that will serve as a barrier to the radiation emitted by the aluminum plate or other material, which carry a paint or coating that presents as a characteristic main a high absorption and low emissivity, which will give as result the well-known "greenhouse effect", base of operation of most thermal solar panels.

The glass will be tempered glass to resist the external conditions and will be coupled in a metallic profile, preferably anodized aluminum, leaving a certain space between the cover and the aluminum plate. The panel so constituted will carry coolant fluid inlet and outlet connections (134a, 407 or others) and will be part of a compression cycle, acting as evaporator In this way, the cooling fluid will arrive in gaseous and high temperature state to the block compressor thermodynamic, after boiling in the panel and in it will increase its temperature and pressure, being driven until condenser consisting of a metallic coil introduced into the inside a tank, which will act as a temperature exchanger, or to an external exchanger, for example plates. Water contained here will be heated thanks to the condensation of the gas refrigerant, which will yield its sensible heat as well as its heat latent to lead to phase change. Once liquid, the fluid reaches the expansion valve located in the block thermodynamic, where its pressure will decrease and with it its temperature of boiling so it will change back to gas phase when it captures calories when circulating through the solar panel, which will exercise evaporator in the installation. Because of the extremely low boiling temperatures of the refrigerant gases, there will always be an important temperature difference between said gas and the environment, being able to work the equipment on cold, cloudy days, with rain, wind or night. The sensor will have a thermostat responsible for stopping the circuit in case the temperature ambient is lower than the boiling temperature of refrigerant, since in that situation the heat transfer necessary for the equipment to generate water heat to the desired temperature, avoiding power consumption, that although reduced, would take place.

The final aesthetics of the flat solar collector Thermodynamic presented here, can be as varied as designs they want to do the same always keeping the requirements indispensable technicians for its operation.

Description of the drawings

To complete the description that is being performing and in order to help better compression of peculiarities of the thermodynamic flat solar collector that we propose, it is accompanied by this specification, as integral part of it, the following figures:

Figure 2, in which the installation is represented complete with sensor and compression cycle thermodynamic

Description of the preferred embodiment

The detailed description of the embodiment preferred of the process of the present invention and of the elements that compose it, it is done in view of both figures. Figure 1 shows the elements that constitute the solar collector thermodynamic plane (1) which are, first of all, the panel of aluminum (2) consisting of two aluminum plates electro-welded inside which is delimited a circuit (3) through which the cooling fluid will flow, counting on an entrance (6) and an exit (7) for the same. On this panel will have a transparent glass cover or solar glass (4), leaving a space between them. This item is responsible for reducing thermal losses and favoring the effect greenhouse inside. Said cover is arranged on the panel secured by an anodized aluminum profile (5), capable of Resist external weather conditions. A thermostat (11) located in the collector, specifically at the rear of the crystal, deals with stopping the circuit in case there is no sufficient heat transfer between the environment and the fluid in moments of very low outdoor temperatures.

Figure 2 shows the complete installation where the thermodynamic flat solar collector can be observed (1) which will be located outside and oriented so that it receives the maximum amount of solar radiation. The cooling fluid comes out of the sensor in a gaseous state and reaches the thermodynamic block (8) where it is compressed and sent at high pressure and temperature to condenser. In this preferred embodiment the capacitor will be a coil (9) inserted inside an accumulator tank (10) of water, which will be heated thanks to the condensation of the refrigerant gas through said coil. Condensed fluid returns to the thermodynamic block (8) where the expansion valve its pressure will decrease, reaching the solar collector where it will pass from new to a gaseous state at the expense of the calories captured from Exterior.
