The development of urban areas by densification of the existing urban infrastructure and setting up of new dwellings raises the question of spatial and temporal distribution of energy supplies to provide thermal comfort. Urban development projects are indeed not necessarily coordinated and may unexpectedly appear, either through new building projects or by opportunistic study of key area, or by...

In this study, an analysis of energy and exergy utilization in the utility sector of Jordan by considering the sectoral energy and exergy flows for the years 2007-2011 has been conducted based on real data obtained from main generators in Jordan. The overall energy and exergy efficiencies, for the entire utility sector, are found to be in the range of 35.1 to 38.1%. It is expected that the resu...

In this study, a new proposed multi-generation system as a promising integrated energy conversion system is studied, and its performance is investigated thermodynamically. The system equipped with parabolic trough collectors and biomass combustor to generate electricity, heating and cooling loads, hydrogen and potable water. A double effect absorption chiller to provide cooling demand, a proton...

Energy determines the ability of matter to work. However, in given environment, real usefulness perform work is determined by exergy. This study covers not only solar, but also any monochromatic thermal radiation. The value such radiation was its exergy and ratio exergy-to-energy. A novelty this demonstrate means that polychromatic can be increased dispersion effect greater, lower temperature A...

This paper presents the energy and exergy analysis of thermal power plant Tuzla in Tuzla, Bosnia Herzegovina. The main aim this is to analyze components a 200 MW steam unit order identify quantify sites with highest losses calculate efficiency values all when operating at nominal load. influence change ambient temperature block load on value was taken into analysis. further includes impact oper...

We use fuel oil as an alternative in compression ignition engines without modification. In this study, we performed tests at different engine speeds using diesel blends a engine. Energy and exergy analysis was carried out the performance emission values got from these tests. Through energy analysis, distribution of determined thermal efficiency calculated. The highest is 34.76% on F40 2250 rpm....
