Renewable Heating And Cooling

Renewable Heating and Cooling: Technologies and Applications presents the latest information on the generation of heat for industry and domestic purposes, an area where a significant proportion of total energy is consumed. In Europe, this figure is estimated to be almost 50%, with the majority of heat generated by the consumption of fossil fuels. As there is a pressing need to increase the uptake of renewable heating and cooling (RHC) to reduce greenhouse gas emissions, this book provides a comprehensive and authoritative overview on the topic. Part One introduces key RHC technologies and discusses RHC in the context of global heating and cooling demand, featuring chapters on solar thermal process heat generation, deep geothermal energy, and solar cooling technologies. Part Two explores enabling technologies, special applications, and case studies with detailed coverage of thermal energy storage, hybrid systems, and renewable heating for RHC, along with case studies in China and Sweden. Users will find this book to be an essential resource for lead engineers and engineering consultants working on renewable heating and cooling in engineering companies, as well as academics and R&D professionals in private research institutes who have a particular interest in the subject matter. Includes coverage on biomass, solar thermal, and geothermal renewable heating and cooling technologies Features chapters on solar thermal process heat generation, deep geothermal energy, solar cooling technologies, and special applications Presents case studies with detailed coverage of thermal energy storage, hybrid systems, and renewable heating for RHC Explores enabling technologies and special applications

Heating and cooling represent significant energy loads around the world, with the associated high level of carbon emissions. Many countries have commitments in place to derive an increasing proportion of the energy they use for heating and cooling from renewable sources; some are seeing greater success than others in moving towards these targets. This best practices handbook from the International Energy Agency's Renewable Energy Technology Deployment (RETD) Implementing Agreement provides energy policymakers and professionals in the renewable energy industry with a practical, easy to use guide and toolkit to the most effective policy options for deploying renewable energy for heating and cooling in the residential sector. The book opens with a comparative review of renewable energy for heating and cooling policies in a broad range of IEA member countries in Europe, Asia and North America and then goes on to present the policy approaches of the individual countries and more detailed studies of specific programmes. The second part of the book presents readers with flowcharts which allow them to navigate directly to the best practices which are most relevant to their situation. Planning, design and implementation are all covered, each with examination of the possible barriers that may be faced and the most appropriate policy response used to date. pUlished with IEA-RETD.

District heating and cooling (DHC) combined with renewable energy sources can help meet rising urban energy needs, improve efficiency, reduce emissions and improve local air quality. Although currently dominated by fossil fuels such as coal and gas, DHC systems can be upgraded, or new networks created, to use solid biofuel, solar and geothermal energy technologies. Depending on local conditions, renewable-based DHC brings a range of benefits, including increased energy security, improved health and reduced climate impact.To date, only a few countries have taken advantage of their renewable resource potential for DHC or created policies to promote further uptake. Sweden and Switzerland have started promoting renewable-based district heating,while Denmark - with ambitious decarbonisation policies -already uses high shares. Many cities and regions envisage a growing role for district in their energy plans; some are also looking increasingly at district cooling.As this REmap sector study from the International Renewable Energy Agency (IRENA) shows, renewables could feasibly supply more than one fifth of the energy needed for DHC worldwide. But to drive the transition, policy makers need to fully understand the costs, bene¿ts and actual potential for renewable-based DHC.

Advances in Solar Heating and Cooling presents new information on the growing concerns about climate change, the security of energy supplies, and the ongoing interest in replacing fossil fuels with renewable energy sources. The amount of energy used for heating and cooling is very significant, estimated, for example, as half of final energy consumption in Europe. Solar thermal installations have the potential to meet a large proportion of the heating and cooling needs of both buildings and industry and the number of solar thermal installations is increasing rapidly. This book provides an authoritative review of the latest research in solar heating and cooling technologies and applications. Provides researchers in academia and industry with an authoritative overview of heating and cooling for buildings and industry in one convenient volume Part III, ‘Solar cooling technologies’ is contributed by authors from Shanghai Jiao Tong University, which is a world-leader in this area Covers advanced applications from zero-energy buildings, through industrial process heat to district heating and cooling

This book provides a manual for the technical and structural design of systems for supplying decentralised energy in residential buildings. It presents the micro-combined cooling, heating & power systems Stirling engines & renewable energy sources (mCCHP-SE-RES) systems in an accessible manner both for the public at large, and for professionals who conceive, design or commercialise such systems or their components. The high performance levels of these systems are demonstrated within the final chapter by the results of an experiment in which a house is equipped with a mCCHP-SE-RES system. The reader is also familiarized with the conceptual, technical and legal aspects of modern domestic energy systems; the components that constitute these systems; and advanced algorithms for achieving the structural and technical design of such systems. In residential buildings, satisfying demands of durable development has gradually evolved from necessity to obligation and institutionalisation. Consequently a major paradigm change has appeared in the supply of energy to residential buildings, from the centralised production of energy using fossil fuels to the decentralised production of energy using local renewable sources. Furthermore, on the energy system market, energy micro systems which use renewable energy sources are increasingly commercialised. From among these, the mCCHP-SE-RES systems are particularly striking because they offer a high performance and they enhance the relationship between humans and the environment. This book is intended for postgraduate students of electrical engineering, applied mathematicians, and researchers of modelling and control of complex systems or power system technologies.

This book offers a comprehensive introduction to novel absorption heating technologies for improving the energy efficiency of heating systems. The proposed low-temperature heating systems, based on an air source absorption heat pump (ASAHP), significantly increase heating efficiency and reduce pollution emissions. As the performance of ASAHPs deteriorates at lower ambient/driving temperatures, a series of advanced cycles is used to extend their applicability, with the compression-assisted ASAHP being the most outstanding example. The book discusses the generator-absorber-heat-exchange ASAHP as a promising solution to make the best of high driving temperatures, an aspect that can be improved further via compression. Further, it addresses the ground source absorption heat pump (GSAHP), which eliminates the soil thermal imbalance of the conventional ground source electrical heat pump (GSEHP), and also reduces the number of boreholes . Various hybrid GSAHP systems are proposed to further enhance applicability, efficiency, and economy: these include a combined GSAHP and GSEHP system, as well as ASAHP and GSAHP systems that incorporate design optimizations. In closing, the book explores the merits of novel working fluids and highlights recent advances concerning waste heat and renewable energy utilization.
