In the present study, performance analysis of a multi effect distillation with thermo vapor compressor (MED-TVC) desalination system coupled to a combined cooling, heating and power (CCHP) system with gas turbine prime mover has been carried out to cogeneration of cooling, heating, power and potable water. The system incorporates air compressor, combustion chamber, gas turbine, triple pressure ...

Purpose of this study was to investigate the sustainability of domestic gas consumption and identify the social factors that affect it. Three questions were asked in this study. 1) How stable is the gas consumption practice at home? 2) What are the elements that affect gas consumption as a sustainable practice?3) What solutions can be offered to increase gas consumption sustainability? After re...

Long-term fluxes of CO(2), and combined short-term fluxes of CH(4) and CO(2) were measured with the eddy covariance technique in the city centre of Florence. CO(2) long-term weekly fluxes exhibit a high seasonality, ranging from 39 to 172% of the mean annual value in summer and winter respectively, while CH(4) fluxes are relevant and don't exhibit temporal variability. Contribution of road traf...

Heating, electricity and transportation are the three components of urban systems final energy consumption. Geothermal energy and biomass are two promising renewable energy resources that can be used for the production of heat, electricity and biofuels, thus allowing a reduction of fossil fuel consumption and of the associated greenhouse gas emissions. The goal of this paper is to assess the po...

A comprehensive survey of 1450 households in 26 Chinese provinces was undertaken in 2012 to identify the characteristics and potential driving forces of residential energy consumption in China. The survey covers six areas: household characteristics, dwelling characteristics, kitchen and home appliances, space heating and cooling, residential transportation, and electricity billing, metering, an...

The energy sector in Romania consists of three sub-sectors: electricity, natural gas and heat. Among these, the sub-sector of thermal energy is in the most precarious situation because it has been neglected for a long time. This sub-sector is particularly important both due to the amount of final heat consumption (of over 50% of final energy consumption), and to the fact that it has a direct ne...

In this paper, an Adaptive-Network-based Fuzzy Inference System (ANFIS) is used for forecasting of natural gas consumption. It is clear that natural gas consumption prediction for future, surly can help Statesmen to decide more certain. There are many variables which effect on gas consumption but two variables that named Gross Domestic Product (GDP) and population, are selected as two input var...

Iran is ranked first in the world in terms of natural gas storage.Natural gas consumption in Iran has always been growing and there has been no effort to save from Iranian households. Per capita energy consumption in Iran is three times the global average and 13 times that of Japan. In this study, we tried to determine the main factors that affect resedential gas consumption. By referring to 38...

The intergalactic medium (IGM) prior to the epoch of reionization consists mostly of neutral hydrogen gas. Lyman-α (Lyα) photons produced by early stars resonantly scatter off hydrogen atoms, causing energy exchange between the radiation field and the gas. This interaction results in moderate heating of the gas due to the recoil of the atoms upon scattering, which is of great interest for futur...

We have analyzed Chandra observations of 18 low-luminosity early-type galaxies with LB ∼ 3×10L⊙B. Thermal emission from hot gas with temperatures between 0.2 and 0.8 keV comprises 5-70% of the total 0.5-2.0 keV emission from these galaxies. We find that the total X-ray luminosity from LMXBs (resolved plus the power-law component of the unresolved emission) scales roughly linearly with the K-ban...
