The electrical resistance heating system was the best regarding to the animals’ thermal comfort needs. Se propone la instalacion de un sistema solar con colectores planos y el aprovechamiento de uno de los dos tanques de agua caliente existentes, donde se efectua la trasferencia de calor al agua por medio de vapor, lo cual disminuye el costo del sistema solar.

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. The thermal analysis of the considered collector was based on the applied methodology the CPC for Hsieh and Leao 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.

T-student tests had been used to detect the significant difference in the average of total cost to being considered the diameter of the wind. Se estudia la dependencia de la eficacia con la nubosidad. We have studied the thermal efficiency of these stills as a function of solar intensity, covers, geometrical configuration, quantity of water, salt concentration and artificial cooling of the cover.

Os sistemas avaliados foram: El tiempo de secado disminuyo notablemente respecto al secado a cielo abierto. With the present work they are sought to analyze the results based on simulations hourly of an installation eolar solar refrigeration by absorption, subjected to different sources of weather data.

Results are also presented for the ray tracing study, from which the optimal characteristics of the receiver are obtained according to the experimental results. La difusion y transferencia de la tecnologia passso a pequenos productores rurales, contribuye a mejorar su aqueceodr de vida al posibilitarles ingresos adicionales.


This tool has been developed from a mathematical model which is composed of a system of equations. ABSTRACT – This experiment was carried out in two phases to study the effect of different heating systems on the productive and bioeconomical performances in broilers. Besides that, this version also allows simulations that consider heat losses at night, situation in which a reverse circulation can occur and mean efficiency loss, depending on the simulated system type.

Then, two different modes of a tunnel dryer are investigated: Sistema de concetracion solar para integracion arquitectonica. The dimensions of the collector, the material and dimensions of the covert, the material and dimensions of the absorber plate, the optic efficiency and the type and thin of the insulator are the fundamentals design parameters that can be varied.

El software fue programado en Visual Basic siguiendo las especificaciones tecnicas de la normatividad vigente en la materia. The objective is to quantify the variation of fluids’ temperature, and correlate it to environment variables, especially solar irradiation.

The solution of the equations system was obtained by the multidimensional version of the Newton-Raphson method. This paper presents some of the preliminary results of the study’s application in an University building, along with the analysis of the initial situation and the proposals for passso handling of reactive energy and the outer and inner lighting as solutions for energy saving.

The current version is capable of simulating 6 different arrangements’ possibilities combined with auxiliary energy: With such elements, monthly regression equations were determined for the estimation of solar radiation as a function of insolation.

To guarantee the good performance of the SSHW, a control and monitoring system for the temperature of the mix inside the biodigester is proposed.

An analysis of thermal performance of these devices operating stationary and without tracking of the sun is researched. Analysis of passive systems as a tool for energy saving in buildings: Preparacion por descarga luminiscente y caracterizacion electrooptica de aleaciones de silicio amorfo para celulas solares. By comparison of both estimated and measured global solar radiation along yeara typical annual visibility series was obtained over every location.

The solar collector was connected to a thermal aqhecedor, also alternative, low-cost forming the system of solar water heating. A fundamental aspect in solar facilities is how to know the incident radiation in the plant which we want to analyze or the size. The objective of this research was to compare the electrical energy use and thermal environment promoted by three heating technologies for piglets in nursery.



This method can be applied to a great variety of thermal systems since it is based on the knowledge of the border condition for the temperature at the surface of the plate, and the temperature profile that characterize the dimensionless coefficient of heat transfer in the fluid, according to its definition given by the Nusselt number.

The used experimental material consisted of boxes of water, pipes of aluminum, hay of grassy, manure of birds and swine, aquarium compressors, hoses and pipes, porous stones, fish lingers and thermometer.

Solar desalination System of Sea Water for Efficient Irrigation of a Crop Module; Sistema de desalacion solar de agua de mar para riego eficiente en un modulo de cultivo. Full Text Available We have constructed three solar stills of areas 0.

These estimations showed root mean square error between 3. Para cumplir con este pr However, the mass transfer coefficient is affected only by the temperature.

Constituiu a amostra 63 pacientes. It is known, also, through studies, that this state possesses high potential for the exploitation of solar energy also for the generation of gsrrafa energy. We studied eight settings between absorber plate, thermal insulating EPS boards and thermal reservoirs and liters.

The heated floor system was considered better than other under the aspect of electrical energy use. Technologies of digital simulation validate the results.

El sistema integrado es una alternativa valida en el marco de una produccion sustentable productiva para pequenos productores. Based on these data, nine models to estimate.

The system worked on a thermosyphon and was tested in two configurations: Debido a que la antena de aluminio tiene un angulo de borde de 90 grados Celcius, es necesario usar un receptor tipo cavidad que permita la captacion de energia tanto interna como externa.

In this context, there are very interesting alternatives, among which is the replacement of electric heating bath water by heating by solar energy. Optimization of a computer simulation code to analyse thermal systems for solar energy water heating; Aperfeicoamento de um programa de simulacao computacional para analise de sistemas termicos de aquecimento de agua por energia solar.
