in this paper, dynamic transient method and conventional degree-hours method (static) have been compared to estimate heating and cooling loads of building’s wall. all main wall surfaces of various orientations, i.e.south, west, east, north, and horizontal are considered in the climate of tehran, iran. in this study, a conventional wall structure, which is comprisedconcrete as main wall material...

integrated energy systems utilizing renewable sources are sustainable and environmentally substitutes for conventional fossil-fired energy systems. a new multigeneration plant with two inputs, such as biomass and solar energy, and four useful outputs, such as cooling, heating, power, and distilled water, is presented and investigated in this paper. the proposed system includes evacuated tube so...

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...

Nowadays, ever-increasing energy demands and the depletion of fossil fuels require efficient environmentally friendly technologies for generation. In this context, systems integration makes a very strong proposition since it results in saving, fuel diversification, supply cleaner energy. To end, is utmost importance to realize current developments field portray state art renewable generation in...
