Maximizing the use of aquifer thermal energy storage systems in urban areas: effects on individual system primary energy use and overall GHG emissions

چکیده
• The primary energy use of ATES systems evaluated for high and low aquifer utilisation levels. High levels reduce individual systems, as more wells can be placed. highest utilization level considered is 115% resulted in 82% adoption. For <80%, buildings not affected by subsurface interactions. >80%, interactions affect gas +15% electricity +/-15%. Low temperature (<25 °C) Aquifer Thermal Energy Storage (ATES) have a world-wide potential to provide low-carbon space heating cooling using heat pumps combined with the seasonal storage recovery heated cooled groundwater. increasingly utilize space, decreasing overall an urban area. However, interaction may negatively performance existing systems. In this study, it investigated how levels, obtained varying well placement policies, between turn affects use. To end, building climate installation model developed integrated MODFLOW-MT3DMS thermal groundwater model. spatial distribution requirements 26 unique present city centre Utrecht, varied agent-based modelling approach applying dense spacious restrictions.

Energy use efficiency, GHG emissions, and carbon efficiency of paddy rice production in Iran
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...

متن کاملEnergy efficiency in a building complex through seasonal storage of thermal energy in a confined aquifer
Confined aquifers are formations surrounded by impermeable layers called cap rocks and bed rocks. These aquifers are suitable for the seasonal storage of thermal energy. A confined aquifer was designed to meet the cooling and heating energy needs of a residential building complex located in Tehran, Iran. The annual cooling and heating energy needs of the buildings were estimated to be 8.7...
