Currently Iran and Morocco are going through an energy transition. Ambitious plans exist at international, regional and national governance levels to deploy renewable energy sources (RES), such as concentrated solar power (CSP) and photovoltaic (PV) solar power. These plans foresee deployment of RES to cover local growing energy needs, to diversify energy supply and to benefit from electricity ...
background: benzene, toluene, ethyl benzene and xylene compounds (btex) are very dangerous in terms of health and environmental and have high toxicity in aquatic environment. the purpose of this study was to investigate the performance analysis of petroleum hydrocarbons xylene using solar radiation uv/tio2 method in industrial synthetic waste . methods: an experimental-interventional study was ...
energy consumption is very high in greenhouses mainly due to off-season production. the main source of its energy supply is fossil fuels. due to the disadvantages of fossil fuels consumption and preventive laws in the incoming years, study on reducing consumption and replacing a part of them with renewable energy is essential. in this research, a solar heating system, equipped with a concentrat...
the steady state effect of vertical fins is assessed on a photovoltaic/thermal solar air heater having a double pass configuration in which fins are placed in the lower channel perpendicular to the direction ofair flow. air passes through the upper channel of the air heater and before passing in the opposite direction through the lower channel. the effects of design, climatic and operating para...
growing tendency for urbanization and rapid development of the cities has resulted in urban neighborhoods obstructing the access of each other to the natural sources e.g. solar energy, natural ventilation. sunlight as the main part of input energy in urban energy balance equation and natural lighting is of vital importance. this paper attempts to achieve an optimum morphology for residential bl...

introduction electrical performance of solar cells decreases with increasing cell temperature, basically because of growth of the internal charge carrier recombination rates, caused by increased carrier concentrations. hybrid photovoltaic/thermal (pvt) systems produce electrical and thermal energy simultaneously. pvt solar collectors convert the heat generated in the solar cells to low temperat...
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 tub...

In the preset study, the performance of a solar assisted heating, ventilation and air conditioning (HVAC) system in an operating theater building was studied. The yearly performances of the existing HVAC system and the system with the added solar collectors were simulated in terms of energy consumption and provided air conditions using a transient system simulation software (TRNSYS). In t...
