Energy Consumption and an Environmental Problem

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Air-conditioning: Energy Consumption and Environmental Quality

Analysis of the energy and environmental efficiency of the transportation sector under the constraints of energy consumption and environmental pollutions in Iran

Economic growth has caused some environmental problems such as energy shortage and environmental pollution. In this regard, in the present study, the analysis of a fixed-sum energy and environmental efficiency to achieve sustainable efficiency in the transport sector of Iran under the limitation of energy consumption and environmental pollution using the Common equilibrium efficient frontier da...

Technology Development, Energy Consumption, Greenhouse Gases Emission and Environmental Pollution in Aluminium Industries

Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...

Environmental and Ecological Effects of Energy Production and Consumption

The exponential increase of energy consumption, since the beginning of the industrial revolution, has produced significant changes in the global environment, chief among which is the increase of the average concentration of carbon dioxide in the atmosphere from 280 ppm in 1750 to more than 390 ppm in 2011. Climatologists predict that this change will cause an increase of the average temperature...
