Assessment of the potential improvement due to multiple apertures in central receiver systems with secondary concentrators. In industry, it is used to dry tea, coffee, rubber, cotton, thread, leather, and textiles. Se necesita un espesor muy reducido para absorber la luz visible: The following present the main applications of these thermo solar elements.

These devices permit direct use of the energy obtained or its transformation into another type of useful energy [1] [2] [3] The concentrator is a device constructed with a high-reflectance material, which permits focusing radiation components released for the sun visible radiation, infrared and ultraviolet rays to avail of and use the energy contained in these signals.

Feasibility study of one axis three positions tracking solar PV with low concentration ratio reflector. Thermal solar concentrators These are devices that permit focusing radiation from the sun on a reduced area focusto concentrate thermal energy and light to easily use it with devices like Stirling motors, heating systems, solar kitchens, vapor turbines, or photovoltaic cells among other devices that operate with thermal energy or with the visible radiation from the sun.

En el interior de este tubo circula un fluido termoportador que capta y transporta el calor. La trama de los actores involucrados usuarios, explotadores, distribuidores, productores, etc. Solar energy collecting system using a primary reflector based on a pyramid structure. The rows of collectors of Shams 1 generate energy that avoids the emissions oftons of CO 2 per year, which is equivalent to removing 15, automobiles from circulation [23].

Sus 2 espejos pivotantes representan una superficie de m2. Table 1 indicates how these are classified according to the temperature reached: By evaporating the water separation of salt is achieved and water suitable for human consumption is obtained Figure 9. Este silicio de estructura desordenada y no cristalina presenta una gran ventaja. Este uses la thermal energy to propel el motor y el electric generator, integrated as a single device, as seen in Figure 2.

This air is circulated through open spaces, with which a constant temperature is maintained, reducing electric energy consumption. The concentrator is a device constructed with a high-reflectance material, which permits focusing radiation components released for the sun visible radiation, infrared and ultraviolet rays to avail of and use the energy contained in these signals. According to the temperature, they are classified according to the range of temperatures reached by the working fluid, which in turn depends on parabolicks type of application for which the device is required.

The solar kitchen shown in Figure 10 is located en Rajasthan, India and has 14 dish-type parabolic collectors, with 10 m 2 of reflecting surface.

A new computationally efficient model and biomimetic layout. El silicio cristalino es capaz de convertir en electricidad una amplia gama de longitudes de onda comprendidas entre y nm, o sea la parte visible y del infrarrojo cercano.

Although thermo solar systems have a vast number of applications in the industrial sector, electric energy production has most-influenced sector by these types of technologies. To meet these requirements, it is indispensable to use fossil fuels like coal, oil, and natural gas, but these generate negative effects because of the emission of residues and contaminating gases onto the environment, as well because of their high costs.

Direct solar radiation, energy, solar collectors, steam, temperature. The water vapor generated is taken to a cooling system condenser to condense it, thus, obtaining distilled water that is then stored in an adequate container.

Temperature in the fluid increases as it goes through the pipes. This technology provides viable and sustainable options over time, which undoubtedly will be of great importance in the near future, which is why there is a need to identify and implement new energy sources capable of providing energy sustainability in the mid- or long-term [1]. La potencia instalada es de 3,2 MW.

Collectors of medium, high, and very high temperature are used to generate electric energy and for activities that require high temperatures like incineration of hazardous wastes. This technology is being implemented to construct large power capacity thermo solar plants in which a support system is also required. Structurally, solar concentrators comprise three necessary elements for their functioning, which are mentioned ahead: Using solar systems to desalinate water requires large areas of land and it is not as efficient when compared to conventional systems non-solarbut its low cost and ease of implementation make it one of the most promising technologies among the applications using direct radiation from the sun [14] [15].

Development of thermo solar energy depends on direct solar radiation, sun shine, availability of surface area, and auxiliary services like water, gas, and electric networks. Many places exist like the Middle East and Africa that do not have enough water suitable for human consumption, even though they coastal zones with access to the sea.

In other versions, energy is used to generate water vapor that is used to propel a vapor turbine and a generator. It starts by providing a brief description of the importance of using solar collectors as an alternative to reduce the environmental impact caused by the production of non-renewable sources paraolicos coal and oil. En este caso, el agua circula por una red de tubos negros paralelos y se calienta lentamente.

The type of working fluid used in this type of collector concentraddores usually demineralized water or ethylene glycol. Incluso se puede modificar paraboilcos espectro de la luz incidente.

Concentrador solar – Viquipèdia, l’enciclopèdia lliure

A review of optimized design layouts for solar power tower plants with campo code. According to their geometric configuration they can be flat solar collectors and concentrating solar collectors.

System element that concentrates the radiation that will then be transformed into another type of useful energy. English pdf Article in xml format Article references How to cite this article Automatic translation Send this article by e-mail. This comprises a group of heliostats flat reflectors aligned in circular manner.

Soluciones al Cambio Climático: una Visión Panorámica

Additionally, the system has an oil boiler that guarantees its operation under all conditions [16] At m above sea level, and when solar radiation peaks are reached on certain parabolucos, the system can provide approximately 38, meals. How to cite this article. Y eso de manera proporcional: All the concentrators have the same operating principle, but present differences regarding geometry, amount of energy concentrated, and how the energy is used.

Usually, it is used in electric power generation facilities with large power capacity.
