Hybrid solar -PLG system for industrial scale steam and hot water generation; Sistema hibrido solar -GLP para geracao de vapor e agua quente em escala industrial. These last three were evaluated before and after the disinfection process effluent parameters.

Then, it would be necessary to have a methodology that indicates what to do in this situation, and for that reason, this work performs an study about the data processing of the obtained measurements to infer values to be incorporated to the series in situations where the data are lost. Solar thermal technology is presented for concentration into a point for the production of heat and energy in small and large scale, emphasis is made on the capacity for the combination with current technologies using fossil fuels for electricity generation and process steam, increasing the global efficiency of the power plants and notably reducing the pollutants emission to the air during the insolation hours.

This design of solar water heater is well suited to Mexican conditions, as it makes use of the high local intensity of the solar radiation, and as the channel shape of the ducts minimizes bursting during the rare occurrences of freezing temperatures in the region; it also has the advantage of being manufacturable at low cost from simple materials. The approach of this work are the foundations of the method and the system that has been developed to apply it, that incorporates automatic acquisition equipment for continuos monitoring of the information and elements to control the parameters of interest.

The concentration of atmospheric greenhouse gases, mainly the CO2, has increased in the last decades due to anthropogenic activities. The tubes were covered with absorbing fins made by recycled aluminum cans. A saline solution that represents produced water was used in the experiments, using sodium chloride ppm. Thereby, it is possible to estimate the solar heating of produced water of petroleum. This work shows how artificial vision feedback can be applied to control systems. To incorporate lost data, the Time Series Analysis based in spatial state models were used.


Explains the design and construction of two types of solar panels for the garrava, one type based on commercial high efficiency multi-junction solar cells and other based pzsso UPC Electronic Engineering Department in-house developed solar cells.

Abstract The main aim of this paper is to evaluate the emissions of carbon dioxide in as consequence of economic activities in developing countries South Africa, Argentina, Brazil, China, India and Mexico.

Solar chimney for the natural ventilation of buildings: Numerical model of simulation for solar collector of water heating; Modelo de simulaco numerica para colector solar de aquecimento de agua. The results point to a low financial viability in the paso of distributed microgeneration projects, suggesting the need to remove the tax burden and reduce financing costs.

To assess the bacteria reactivation we kept the water in bottles for 24 hours, pretending a very common situation in Brazilian rural houses. The equipment revealed technical viability, reaching the minimum temperature of 35 deg C for shower, whenever the solar radiation was above the W.

Aquecedor solar de baixo custo – PET

The collector consists of five plates of PVC with 10 mm thick, mm wide and mm length, with ao area equal to 1,4 square meters.

Ao longo do aquecimentoo teor de carotenoides foi praticamente todo degradado e consequentemente a cor foi bastante alterada. The development and implementation of these devices in various countries of the world, has allowed us to evaluate the technical feasibility of the technologies associated with the development and use of Renewable Energies to solve the global energy problems, and, in this way, achieve the long-awaited energy independence to which aspire all the nations of the planet.

The water temperature achieved the tank at the end of the day averages 65 degrees Celsius in winter weather conditions in the central Mexican highland. The objectives of the work were: Aproveitamento dos subprodutos da extra??

Como fazer um Aquecedor caseiro p/chocadeira

The absorbing surface of the collector is formed by twelve PVC pipes of 25 mm outside diameter connected in parallel via connections in T of the same material. A clean option to obtain hydrogen is the utilization of such renewable sources.

The influence of each of the preparation parameters on film properties has been systematically studied. The main idea is to make a blend of various existing systems in order to produce an efficient and cost effective prototype. Para ello se desarrolla: This collector works with natural convection. The room temperature and the speed of the wind were also evaluated, verifying its influence in the heating system.


The sample comprised news items from more than 3, published on the topic between October and October For the Peruvian conditions the more adequate solar water system for a rural or domestic usage is a 1.


We presentboth the conceptual design of the experimental results. The tests showed good performance of the system. This paper will address the use of solar energy with the basic purpose of heating water for bathing in popular residences and in isolated rural areas, using low cost systems, built with easily materials that is found in any area of the country.

Construimos un calentador de agua solar para trabajar la sostenibilidad. Analysis of solar radiation and other variables for the evaluation of locations of thermo solar power stations; Analisis de radiacion solar y otras vairables para la evaluacion de emplazamientos de centrales termosolares.

Escola de Engenharia], Emails: Mediciones de temperatura por un periodo de 30 dias, arrojaron valores. The state of the Ceara imports most of its consumed energy, configuring itself as a region eminently energy importer. The theoretical methodology use here is based upon the Gagrafa paper paeso, and in attrition is considered the hot water drainage due to the dally consumption. To know all the factors that influence the s of a system of water heating by solar energy it is important the determination of its economic and technical viabilities and, distribution targeting in urban and agricultural residences.

A flat solar collector built from galvanized steel plate, working by thermosyphonic flow, optimized for Mexican conditions; Un colector solar plano construido de lamina de acero galvanizada, operando por flujo termosifonico, optimizado para las condiciones mexicanas. Ademas de brindar un documento de consulta entre los profesionales dedicados al dise y como base de consideraciones bioclimaticas que debe tener el reglamento de construcciones.

Com a crescente disponibilidade de dados observacionais sobre estrelas T Tauri, a busca por modelos mais precisos vem se tornando cada vez maior.

This paper presents the development of a solar oven fordrying plants and vegetables using fuzzy control. El trabajo que aqui se reporta esta enfocado a la fundamentacion del metodo y al equipamiento que se ha desarrollado para instrumentarlo, que incorpora equipos automaticos de adquisicion continua de informacion y elementos de control para los parametros de interes.

La Memoria del Proyecto describe los componentes y procesos involucrados para alcanzar los objetivos. Os resultados obtidos foram os seguintes: The solar assisted system proposed uses flat plate solar collectors integrated with an existing hot water tank, where water is heated with vapor from a diesel ran boiler.
