A procedure to evaluate the quality of solar thermal installations is proposed, following some analogy to the Calificacion Energetica de Viviendas C. In this system, the total aquecedlr outside the brooding area could be maintained at 0,11 m. Ill email you some time. Interference of heating on the antimicrobial activity and chemical composition of Origanum vulgare L. The garrafx idea is to make a blend of various existing systems in order to produce an efficient and cost effective prototype.

Aquecedor solar de baixo custo – PET

From these measures, a theoretical and experimental methodology was developed and applied for the evaluation of the heat and mass transfer coefficients that govern this process. To estimate this variable, empirical models have been developed using several parameters and, recently, prognostic and prediction models based on artificial intelligence techniques such as neural networks.

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 system showed great potential for application, usability and effectivity.

In view of this problem, the objective was to examine how the use of solar distillers can provide the production of drinking water, and assess pe socio-economic and environmental benefits from the use of this technology.

Os subprodutos da extra?? La difusion y transferencia de la tecnologia desarrollada a pequenos productores rurales, contribuye a mejorar su calidad de vida al posibilitarles ingresos adicionales. In the last years several applications, which had the sun as their electric energy resource, were implemented in the rural areas of many countries.


Have you considered including some social bookmarking links to these sites. In terms of receiving surface, the prototype tested here has an area of 1.

DAMIRA AGUIAR LTDA. by Daniele Mota Cunha on Prezi

The heated floor system was considered better than other under the aspect of electrical energy use. On the other hand, it is described a simplified method to design solar collectors based on the determination of minimum entropy generation during the thermal conversion of the solar device by using the thermal analysis procedure established and the method derived of the second law of the Thermodynamics are finally presented.

It was concluded that this system attended the proposed objectives, producing clean hot air that can be used for drying purposes as well as ambient space heating. A computational program was developed to assist the study of several configurations that optimizes the implantation cost of an wind- solar through considered mathematical model.

aquecimento solar para: Topics by

First, a preliminary dryer design procedure is described step by step. The system operated without interruptions and it did not need maintenance, except for the monthly aqyecedor cleaning.

It has tree systems: The use of renewable approaches of energy, that are ‘infinite’ energies as the wind and the light of the sun, for examplecan become an excellent alternative. The developed mathematical model was garfafa through the Multiple Linear Regression technique, on the basis of the previous knowledge of variables: Irreversibility analysis of non isothermal flat plate solar collectors for air heating with a dimensionless model; Analisis de las irreversibilidades en colectores solares de placas planas no isotermicos para calentamiento de aire utilizando un modelo adimensional.

Dois experimentos foram realizados separadamente. To achieve this purpose, we appraise the causes of global warm and the main uses of fossil fuels and silar these factors affect the world economy.

We analyzed three options for water heating with tank accumulation: Full Text Available In Costa Rica, there has been a growing interest to use pineapple fiber from plant, for which current processes need to be improved or new processes need to be developed, with emphasis on drying methods.


Email me if you get the chance and share your wisdom. In order to test and calibrate models for estimating solar radiation data were collected from four meteorological stations belonging to the National Institute of Meteorology INMET to represent the climatic region northwest of Minas Gerais for the period from to Despues, se analizan cualitativamente dos secadores: The use of per energy in systems of agricultural residential water heating, can complement the economy of electric energy, base of the Brazilian energy matrix.

Se realizan ejemplos de aplicacion, donde se obtienen ciertos resultados de los cuales se hace una breve discusion. Three tons of moist corn were dried.

Aquecedor solar feito de garrafas PET

One of the most important requirements to make a project of rational use of solar energy is the precise knowledge of the temporal-spatial sllar of the solar resource on the terrestrial surface.

Besides being an available natural resource, the solar energy is very applicable in places with few recourses and low money resources, because there aren’t either the need of chemical products neither a huge cost commercial materials can be reused.

I was basically curious about if you ever considered modifying the design of your site?

Several additives have been used. The influence of the design parameters on the entropy generation by fluid friction and heat transfer is analyzed and it is found that for certain combinations of these parameters optimal thermodynamic operation can aqyecedor achieved. Technologies of digital simulation validate the results. Application examples are performed, obtaining certain results that are discussed briefly.

A compound collector for some formed V-trough concentrators can be an alternative to the conventional solar collectors flat plate.
