[ 1 ] - ارزیابی ترمواکونومیکی سیستم ذخیره ساز انرژی خورشیدی در گلخانه به منظور کاهش مصرف سوخت
در این پژوهش استفاده از یک سیستم ذخیره ساز انرژی خورشیدی در گلخانه ها با هدف کاهش مصرف سوخت امکان سنجی می گردد. در این راستا، انرژی خورشیدی در دسترس از روش ایزوتروپیک و با تکیه بر سایر قوانین معتبر علمی محاسبه گردیده، آنالیز انرژی بر روی گلخانه نمونه صورت می پذیرد و میزان سرمایه گذاری اولیه بر اساس...
[ 2 ] - Dynamic Modelling of a Compressed Air Energy Storage System in a Grid Connected Photovoltaic Plant
The use of photovoltaic (PV) cells in domestic and industrial applications has grown rapidly through the recent years. Constructing PV plants is a very smart measure to produce free electricity in large scales, especially in the countries with higher solar irradiation potential. On the other hand, compressed air energy storage (CAES) has already been proposed to be employed for energy storage a...
[ 3 ] - Fuel Consumption Minimization in Greenhouses by Employing an Innovative System Taking Advantage of Solar and Geothermal Energies
Replacing fossil flues by renewable and sustainable energies have been the concern of scientists working in this area over the recent decades. Furthermore, greenhouses play a key role in producing various crops year-round and in bohemian climates. For this objective, the greenhouses employ heating, ventilating and air conditioning (HVAC) systems to provide the favourable conditions for the cons...
[ 4 ] - Proposing a Novel Configuration for CGSs Aimed at Reducing Energy Consumption and Exergy Destruction
A CGS is of the most important parts in natural gas transmission pipelines in which the high inlet natural gas (NG) pressure is reduced to much lower value by employing a throttling valve. This pressure drop causes hydrate forming, preventing stable NG flow through the pipeline. To prevent hydrate forming, NG is usually preheated by heaters which burns remarkable amount of NG. In this work, a n...
