This study evaluated the energy saving potential of renewable generation systems based on integrated solar in an urban environment. The city concept was implemented using photovoltaic (PV) and thermal systems. As a case study, Sejong national pilot smart South Korea selected to evaluate penetration rate. For evaluating proposed systems, electrical loads were estimated field measurement data. Th...

This study was born in the context of new challenges imposed by the recast of the EU Energy Performance of Buildings Directive. The aim of this work is to develop strategies to identify and investigate the relationship between decisional variables within a nZEB design concept, providing a useful method to deal with a huge number of simulations corresponding to a large number of building configu...

1. Abstract This paper presents two approaches developed at the Australian National University for modelling the transient response of a parabolic dish steam cavity receiver. Both approaches are based on a heat transfer model for a cylindrical pipe using a moving-boundary formulation, and feature the ability to model multiple phase flow that changes dynamically. A model simulation is implemente...

Abstract In city gas pressure reducing stations, in order not to hydrate natural after a sudden drop pressure, the temperature is raised by heater. The increase such that drop, inside pipes does freeze. These heaters are burning and very high consumption, because they use fossil fuels, produce environmental pollution. Accordingly, this research, solar energy will be used preheat gas, which for ...

Conventional basin-type solar still (CSS) is the simplest type of water distillation system. In this study, CSS was modeled and simulated. The effect variations in mass inside basin, absorber absorptivity, glass reflectivity heat loss coefficient were investigated. Finally, system simulated using same data radiation intensity, ambient temperature wind speed each variation highest distilled resu...

To take advantage of the data generated in buildings, this document proposes a methodology based on machine learning model to improve thermal comfort and energy efficiency. This uses measured (e.g., indoor/outdoor temperature, relative humidity, etc.) forecast meteorological data) train multiple linear regression indoor temperature space under study. Using genetic algorithm optimization method,...

Abstract The topic of energy saving is a constant in everyday life, and it widespread all over the world. Space heating using solar panels most used renewable source energy, but application for cooling fluids refrigeration growing very fast. Among techniques refrigeration, this work focused on Desiccant Cooling. In particular, with use dynamic simulation software, was possible to study heat sup...

Climate change and resource energy depletion are already impacting ecosystems societies around the world. As a result, environmental sustainability has become one of humanity’s priority challenges. This study aims to use ecological multilayer material in order reduce impact carbon needs heating severe climates which people die each year from cold. The combination investigated gives low thermal ...

In the recent times, the use of solar energy for the refrigeration purpose has been increasing day by day. Generally, solar used for cooling purpose has proposed many advantageous features in the refrigeration field. The cooling path is basically depends on the amount of solar radiation. The more amount of solar radiation directly increases the C.O.P. of the system. In this research paper, the ...
