many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (asf) of such systems. in this paper, the behaviour of integrating the phase change material (pcm) in sdhw systems is modelled and optimized numer...

Recently Debates about Energy and the issue of global warming have led to the use of new energy. One of the best options for this purpose is the use of a new hybrid system of power, heating and refrigeration, with its thermal source of solar and geothermal energy. In the present study, used a combined cooling, heating and power system based on the organic Rankine cycle and the Ejector Refrigera...

Solar panel is popular renewable energy technology because it environmentally friendly, zero emissions, and clean.  However, the conversion value from solar radiation to electricity quiet small, more than 70% of discharged into heat energy.  Therefore, a collector needed take advantage dissipation panel. In this study, an air placed at bottom indicating potential energy, electrical efficiency e...

Hybrid air conditioning systems can allow significant energy saving and emissions reductions with respect to conventional air-conditioning systems. Thermal analysis of a desiccant wheel, heat exchanger, ground source circulation system, solar collector for hybrid system is performed in this study. The effects these parameters have been studied: Inlet temperature, humidity ratio, wheel speed, re...

In this paper, on the basis of Green Comprehensive Plan at Hakim Sabzevari University of Sabzevar, Iran, the application of active solar  systems for the dining hall is evaluated. The impact of solar systems and energy management designed for this hall on energy consumption and environment was investigated.This study measures the electricity and thermal energy consumption of the dining hall , p...

This study represents a year-round energy performance of two solar water heating (SWH) systems with a 4m2 flat plate collector (FPC) and an evacuated tube collector (ETC) operating under the same weather conditions. The energy performance of the two considered systems was compared on a monthly and yearly basis. The obtained results showed that for an annual total solar insolation of ...

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...
