in this paper, optimal design of hybrid solar-wind- diesel energy system with battery storage for reliable load in arsoon village in ardabil is presented. the village has 35 households that mean daily energy consumption is estimated 63.4 kwh. in this design optimization is implemented, considering loss of power supply probability (lpsp) index for reliable load providing, with minimum total cons...

This study aims to determine the average value of hot water temperature and thermal efficiency that can be produced by using iron pipes as fluid collectors in Solar Energy Water Heater design system. Collector are made three variations 5, 7 9 which placed a wooden box with transparent glass cover on collector surface. The inside is lined styrofoam aluminum foil reduce heat loss environment. Dat...

This article presents the results of experimental studies main thermal characteristics a solar collector, heated air duct an indirect type drying plant for agricultural products. The temperature measurement at lower, middle and upper parts entrance output heater different radiation intensities during day in periods month city Tashkent are given. calculation volume flow through heater, specific ...

In this investigation, the effect of replacing conventional solar absorber with a new on thermal performance double-pass air heater has been studied experimentally and numerically. Three configurations have introduced, first configuration is double pass flat plate (DPSAHWFP) for aim comparison, second tubular that includes set tubes which are fitted perpendicularly to direction airflow (DPSAHWT...

CFD analysis of 2-dimensional artificially roughened solar air heater duct with additional circular vortex generator, inserted in inlet section is carried out. Circular transverse ribs on the absorber plate are placed as usual. The analysis is done to investigate the effect of inserting additional vortex generator on the heat transfer and flow friction characteristics inside the solar air heate...

This study is concerned with the results of a Life Cycle Assessment comparison between photovoltaic e silicon based modules and thin film modules e and solar thermal systems, as technologies which are usually installed for partially covering household energy demand. Several studies focused on energy and environmental performances of photovoltaic and solar thermal collectors, however they have b...

In this paper, a cascade control strategy is applied to the temperature inside hybrid solar-gas dryer. order use dryer even at night and in unfavorable weather conditions, drying chamber heated by two systems. The first one solar air heater second gas heater. collector relatively slow compared heating system. Static dynamic studies were established have revealed nonlinear behavior of each subsy...

The paper reports on the optimization of a heater used in a Thermoluminescence glow curve apparatus. Two variants of the heater, planchet system and block system, are described. Both variants performed by a cheap material as graphite and designed following cryogenic principles, are very simple constructively, ensure minimum heat losses and require

The biggest problem faced by the world these days is pure drinkable water, and in a few years, water will not be easily available, as it becoming brackish saline due to pollution. By using solar energy, still can produce which used for drinking, cooking, also industrial purposes. In this research, based on clean technology energy drive system that operated with an approximately negligible maint...
