Download or read book District Heating and Cooling Networks written by Antonio Colmenar Santos and published by MDPI. This book was released on 2020-05-12 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional thermal power generating plants reject a large amount of energy every year. If this rejected heat were to be used through district heating networks, given prior energy valorisation, there would be a noticeable decrease in the amount of fossil fuels imported for heating. As a consequence, benefits would be experienced in the form of an increase in energy efficiency, an improvement in energy security, and a minimisation of emitted greenhouse gases. Given that heat demand is not expected to decrease significantly in the medium term, district heating networks show the greatest potential for the development of cogeneration. Due to their cost competitiveness, flexibility in terms of the ability to use renewable energy resources (such as geothermal or solar thermal) and fossil fuels (more specifically the residual heat from combustion), and the fact that, in some cases, losses to a country/region’s energy balance can be easily integrated into district heating networks (which would not be the case in a “fully electric” future), district heating (and cooling) networks and cogeneration could become a key element for a future with greater energy security, while being more sustainable, if appropriate measures were implemented. This book therefore seeks to propose an energy strategy for a number of cities/regions/countries by proposing appropriate measures supported by detailed case studies.

Download or read book A System Perspective on Energy End Use Measures in a District Heated Region written by Stefan Blomqvist and published by Linköping University Electronic Press. This book was released on 2019-06-04 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: A district heating and cooling (DHC) system can be a viable piece of the puzzle in the efforts of reducing the greenhouse gas (GHG) emissions. Especially if the DHC system include combined heat and power (CHP) plants which enable electricity production from renewable resources. This is set forth in national energy targets and sustainable development goals (SDGs), adopted by the United Nations in 2015. Moreover, improved energy efficiency and energy savings are important factors in fulfilling the national targets of decreased energy intensity as well as reducing the use of fossil fuels. The aim of this thesis is to analyze the impacts of two energy end-use measures in a DHC network and their consequences on the efforts towards sustainable development. The end-use measures studied are (1) renovation of a multifamily building stock and (2) the use of a hydronic pavement system (HPS) including analysis of different control strategies. The end-use measures are assessed in terms of energy use and efficiency, use of renewable and fossil resources, and local and global GHG emissions. Lastly, it is analyzed how the results relate to national energy targets and SDGs. By using simulation and optimization models, several scenarios of end-use measures are analyzed in the two studies. In the first study, six scenarios are analyzed, as the renovation packages include measures on the envelope, ventilation and conversion from district heating to ground source heat pump. In the second study three scenarios are analyzed, where the HPS are operated all-time at a temperature below 4°C or are shut down at temperatures below -10°C or at temperatures below -5°C. The results of the study regarding the renovation of a multifamily building stock indicate a future reduction in heat demand. All scenarios show energy savings of the studied building, which ranged from 11% to 56%. All scenarios show a reduction in local GHG emissions, as well as reduced fossil fuel use. Although the largest reduction was found in the use of renewable resources. From a global perspective on GHG emissions, the scenarios with district heating out-performed measures with heat pump solutions in the studied system. Moreover, the study point to positive impacts on the efforts towards SDGs. To mitigate the reduced heat demand from the renovation of the building stock, an HPS may be used. The results show mostly renewable resources were used for the HPS. The use of HPS was found to generate a positive impact on global GHG emissions. A control strategy that shuts down the HPS at temperatures below -10°C would result in 10% energy saving and would maintain acceptable performance of the HPS. Furthermore, it would reduce the use of fossil fuel and reduce local GHG emissions by 25%. Moreover, an HPS may contribute to SDGs. It is concluded that energy end-use measures of renovating a multifamily building stock are vital in the work towards an improved energy intensity. However, these measures result in a decreased demand for heat in the DHC network. This can then lead to reduced electricity production from renewable resources in the CHP plants, which in turn have a negative impact on the global GHG emissions. By finding new applications, like HPS, the infrastructure of DHC networks could be utilized efficiently and serve as one piece of the puzzle that is the efforts towards sustainable development. Ett fjärrvärme- och fjärrkylenätverk kan vara en viktig del i arbetet att minska växthusgasutsläppen. Speciellt då ett fjärrvärme- och fjärrkylenätverk nyttjar kraftvärme, vilket möjliggör elproduktion från förnybara resurser. Detta efterfrågas i de nationella energimålen och i de globala målen för hållbar utveckling, även kallade Agenda 2030, som antogs av Förenta Nationerna 2015. Dessutom är förbättrad energieffektivitet och energibesparing viktiga faktorer för att nå de nationella energimålen för minskad energiintensitet. Syftet med denna avhandling är att analysera effekterna av två användningsåtgärder i ett fjärrvärme- och fjärrkylenätverk, samt dess konsekvenser för en hållbar utveckling. De åtgärder som undersöks är (1) renovering av ett flerbostadshusbestånd och (2) användningen av ett markvärmesystem. Användningsåtgärderna analyseras utifrån energianvändning och energibesparing, användning av förnybara och fossila resurser, samt lokala och globala växthusgasutsläpp. Slutligen analyseras hur resultaten relaterar till nationella energimålen och de globala målen för hållbar utveckling. Genom att använda simulerings- och optimeringsmodeller analyseras flera scenarier av användningsåtgärder i de två studierna. I den första studien analyseras sex scenarier, där renoveringsåtgärderna innehåller klimatskals- och ventilationsåtgärder, samt ett byte av värmesystem från fjärrvärme till värmepump. I den andra studien analyseras tre scenarier. Ett då markvärmesystemet drivs kontinuerligt vid en utomhustemperatur under 4° C, samt då systemet även stängs av eller försätts i viloläge vid utomhustemperaturer under -10°C respektive -5°C. Resultaten från den först studien pekar på ett minskat värmebehov i framtiden. Alla scenarierna innebar energibesparingar i den studerade byggnaden, som varierade från 11% till 56%. Alla scenarier uppvisade en minskning av lokala växthusgasutsläpp, samt minskning av fossil bränsleanvändning. Dock ses den största minskningen i användandet av förnybara resurser. I ett globalt perspektiv på växthusgasutsläpp, så presterar värmelösningar med fjärrvärme bättre än de med värmepump i de studerade systemen. Studien uppvisar positiva effekter på de nationella målen, samt de globala målen för hållbar utveckling. För att möta den minskade värmebehovet kan ett markvärmesystem nyttjas. Resultaten visar att främst förnybara resurser används. Användningen av markvärme har en positiv inverkan på globala växthusgasutsläpp och en kontrollstrategi som försätter markvärmesystemet i vila vid temperaturer under -10°C kan resultera i 10% energibesparing samtidigt som en acceptabel prestanda bibehålls. Detta minskar den fossila bränsleanvändningen, samt de lokala växthusgasutsläppen med 25%. Ett markvärmesystem kan bidra i arbetet med de nationella målen, samt de globala målen för en hållbar utveckling. Slutsatsen är att renovering av ett bestånd av flerbostadshus ska genomföras i arbetet för en minskad energiintensitet. Dessa åtgärder leder emellertid till en minskad efterfrågan på värme. Detta kan minska elproduktion från förnybara resurser i kraftvärmeanläggningarna, vilket i sin tur har en negativ inverkan på de globala växthusgasutsläppen. Genom att hitta nya applikationer, som markvärme, kan infrastrukturen i fjärrvärme- och fjärrkylenätverk nyttjas effektivt fortsättningsvis och fungera som en bit i pusslet för en hållbar utveckling.

Download or read book Bridge Management 5 written by G. A. R. Parke and published by Thomas Telford Publishing. This book was released on 2005 with total page 696 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains over eighty papers covering the fields of bridge management systems, inspection methods, structural assessment and maintenance strategies; together with the reliability and risk management techniques. This book is useful for bridge owners and engineers engaged in bridge design, assessment, repair and strengthening. The last five years have seen the art of bridge management develop into a mature subject. Bridge owners and engineers recognise the importance of implementing fully operational bridge management strategies to ensure that all road and rail bridges remain functional for as long as possible. Bridge structures form a major part of the vast financial investment in infrastructure and consequently their careful management involving structural appraisal, repair and strengthening is of paramount importance. Factors such as the chosen repair method can influence how often and for how long a bridge structure is out of operation. This in turn, determines the ensuing traffic and/or rail delay costs and also any resulting increase in traffic pollution.The 5th volume on Bridge Management contains over eighty papers which span the fields of bridge management systems, inspection methods, structural assessment and maintenance strategies; together with the latest reliability and risk management techniques. Almost all of these papers have been presented at the Fifth International Conference on Bridge Management held at the University of Surrey in Guildford, UK in 2005. The book will prove to be a very useful reference manual for all bridge owners and engineers engaged in bridge design, assessment, repair and strengthening. The volume is also recommended as a reference text for other professionals who are concerned with care of the environment and the minimisation of pollution due to traffic delays and non-conventional repair and protection methods.
