Air conditioning is an important part in building services world-wide in both commercial and residential buildings. With the general attempt to reduce the usage of fossil fuels and increase the usage of green solutions, the market for solar air conditioning is growing rapidly. Solar air conditioning combines solar thermal absorbers to transfer solar radiation into heat with heat-driven cooling ...

The amine regenerator of acid removal unit in South Pars Gas Complex, Assalouyeh, Iran was modeled. This model was fitted to assess the large scale columns and allow application of solar thermal energy for production of low pressure steam. Heat transfer fluids including Therminol oil, sulfur, or salt melt could be applied to yield thermal energy from a solar collector and to store and transfer ...

In this article, a Colombian field was chosen which is located in Puerto Nare, Antioquia where there good location to install Concentrated Solar Power (CSP), consists of concentrating heat through the sun, generate steam and supply it also be able do without absence solar irradiation, article LCOE calculation will evidenced by System Advisor Model (SAM) simulator taking into account different f...

Induction Heating system utilizes electricity for the generation of heat, whereas solar energy is largely available energy source for generation of heat. Combining solar energy with induction heat generation technique is the efficient solution for the heat generation application. The proposed system presents an effective control scheme incorporated in half bridge series resonance induction heat...

A hybrid solar panel has been invented to integrate photovoltaic (PV) cells onto a substrate through a functionally graded material (FGM) with water tubes cast inside, through which water serves as both heat sink and solar heat collector. Therefore, the efficiency of PV cells can be improved by temperature control while the heat conduction to the substrate can be minimized for saving of air con...

Two novel hybrid combined cycle power systems that use solar heat and methanol, and integrate CO2 capture, are proposed and analyzed, one based on solar-driven methanol decomposition and the other on solar-driven methanol reforming. The high methanol conversion rates at relatively low temperatures offer the advantage of using the solar heat at only 200–300 C to drive the syngas production by en...

introduction nowadays, due to higher environmental pollution and decreasing fossil fuels many countries make decisions to use renewable fuels and restrict using of fossil fuels. renewable fuels generally produce from biological sources. biodiesel is an alternative diesel fuel derived from the transesterification of vegetable oils, animal fats, or waste frying oils. considering the differences be...

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...

introduction controlling greenhouse microclimate not only influences the growth of plants, but also is critical in the spread of diseases inside the greenhouse. the microclimate parameters were inside air, greenhouse roof and soil temperature, relative humidity and solar radiation intensity. predicting the microclimate conditions inside a greenhouse and enabling the use of automatic control sys...

In this paper, a model for closed loop solar system is presented and an attempt is made to generalize the model to be utilized for primary design of any solar active thermal system. This model may be used for systems in which gas or a liquid are fluids that flow. Two new parameters, namely, the system heat delivery factor and the system heat absorption factor are introduced in the model. These ...
