The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...
Significant energy is used to provide and maintain environmental conditions for thermal comfort in high-rise residential buildings, which largely depends on the components of the shell design. Therefore, to achieve high amounts of energy savings in buildings, high-impact design measures must first be defined and then optimized. This study seeks to answer the question of how the components of th...
Buildings are responsible for a large fraction of the world’s total electrical consumption. Energy awareness of residents, by means of timely electrical consumption feedback through smart metering, aims to reduce the waste of energy. Further savings can be achieved by leveraging social norms and entertainment to drive sustainable behavior. In this paper, we investigate two important pillars in ...
Transformative impacts on our energy security rely on creative approaches for consumption and generation of electricity. Technological contributions can impact both areas if they focus on problems of scale. For example, occupancy-based electrical loads (HVAC and lighting) accounted for roughly 50% of the total consumed electricity in the U.S. in 2008. Meanwhile, roughly 50% of consumed oil in t...
With development of distributed generation in industrial microgrids (IMGs), the energy management program is used for optimal scheduling of production and consumption that reduced the operation cost. By restructuring in power systems and increasing energy prices in some hours of the day, more attention has been paid to the demand side management programs. In this paper a new model for controlla...
About 20% of the electricity produced in the world is consumed in rotary equipment for conveying fluids such as water, gas, air, and other liquids, while the loss of energy consumption in this sector is more than 60%. The aim of this study is to evaluate different efficiencies in the pumping stations in the pressurized irrigation systems to address low energy efficiency issues in the pump stati...
In this study, we will investigate the possibility of using renewable energy resources in area where electrical energy is not supported. We will consider it as a micro-grid and we will try to supply its electrical energy by decreasing cost and having reliability in system. Generally, the main reason of designing and developing of distribution grid is responsible to growth of electrical consumpt...
