Finally, the economic feasibility of the solar water system is demonstrated when it is compared with the usual immersion electric resistance boiler. Interconnection of the absorbers tubes forms a similar tubular network existing in solar collectors of the type the plate and pipe.

In absolute terms, the panel is the most frequently cited source, since just seven news items comprised exceptions to the ‘consensus. Before being installed a solar heater, It must be tested, numerical or experimentally to get his characteristic equation, which is the efficiency curve, plotted as a function on the temperature of entry and solar incident radiation on the collector. According to several sources the electric shower, as it is now simple and extremely cheap, is the villain of the national electrical system.

Therefore, this paper presents some technical subsidies applied to rural homes, even to lower income people’s homes aiming to stimulate the Brazilian public authorities to make a public police to facilitate both the industrialization and dissemination of solar heating systems, appropriate to the rural area, with lower costs, compounded by good technology equipment, with guarantee of lasting and quality.

Mediciones de temperatura por un periodo de 30 dias, arrojaron valores. Crunchy numbers The concert hall at the Sydney Opera House holds 2, people. The results point to a low financial viability in the implementation of distributed microgeneration projects, suggesting the need to remove the tax burden and reduce financing costs.

The dimensionless model developed and validated by Baritto and Bracamonte for the thermal behavior of flat plate solar collector without glass cover is improved by adding the entropy balance equation in a dimensionless form.

To assess the bacteria reactivation we kept the water in bottles for 24 hours, pretending a very common situation in Brazilian rural houses. The results of the analysis show that, the thermal efficiency is not sufficient to rate de dryer performance.

We evaluated thermal parameters that proved the viability of the heating system studied. Este trabajo presenta algunos de los resultados preliminares de la aplicacion del estudio en un edificio de la Universidad junto con el analisis de la situacion inicial y las propuestas del manejo de energia reactiva, de iluminacion exterior e interior como soluciones para el ahorro de energia. The dryer has received great acceptance by the industry due to its low cost and good operating efficiency.

In Ecuador there are many non-electrified remote areas, especially in the province of Pastaza, in this article a solar absorption cooling system is presented as an alternative for the air conditioning of a doctor’s office medical clinic in Community Kumay.

The present study was conducted to evaluate the suitable temperature and thickness of the poultry litter related to the electric heating systems glass fiber and armed mortar and regarding the ambient temperature variations.

The most commented on post in was The Elle tie-on – chinelos feitos com sobras de tecido.


Thermochemical cycles based on metal oxides for solar hydrogen production; Ciclos termoquimicos basados en oxidos metalicos para produccion de aqquecedor solar. It also controls the input and output temperature to the solar collectors, as well as the cost analysis which shows the savings of fuel of the SSHW with a conventional system to heating water.

The jack fruit almonds were dried whole, half, with pellicle and without it. First, the experiments for the determination of the angular error of the concentrator and the dimensions of its focal region are described.


By the degree of development of both technologies it is advisable to present them in different sections. It will be presented the thermal efficiency, heat loss, water temperature of the thermal reservoir at the end of the process and simulation of baths for a house with four residents.

Development of tool for optimization in the measurement of solar radiation; Desarrollo de herramientas para la optimizacion en la medicion de la radiacion solar.

Notes for a procedure of certification of thermal solar facilities; Apuntes para un procedimiento de certificacion de instalaciones solares termicas.

In this new energy group, the solar energy transformed by the use of photo voltage cells is becoming very important. Factors like functionality, maintenance, organizational and space limitations, and costs were analized.

A parametric study is developed and the distribution of internal irreversibilities along the collector is analyzed.

This work presents results of the application of a model of solar -wind hydrogen energy for the Ceara state and variables such as population, gross intern product, energetic demand, energy imports, fossil fuel and hydrogen prices, income from hydrogen sale, and others parameters. Os valores de temperatura em cada ponto determinado foram coletados de 5 em 5 minutos. Application examples are performed, obtaining certain results that are discussed briefly.

Almond cut in half and the pellicle removed reduced the drying time. In the system proposed, which uses flat collectors, both natural and forced convection are responsible for the transfer of heat to the circulating water. Radiative transfer model for estimation of global solar radiation; Modelo de transferencia radiativa para la estimacion de la radiacion solar global.
