Advanced District Heating and Cooling (DHC) Systems


Book Description

Advanced District Heating and Cooling (DHC) Systems presents the latest information on the topic, providing valuable information on the distribution of centrally generated heat or cold energy to buildings, usually in the form of space heating, cooling, and hot water. As DHC systems are more efficient and less polluting than individual domestic or commercial heating and cooling systems, the book provides an introduction to DHC, including its potential contribution to reducing carbon dioxide emissions, then reviews thermal energy generation for DHC, including fossil fuel-based technologies, those based on renewables, and surplus heat valorization. Final sections address methods to improve the efficiency of DHC. - Gives a comprehensive overview of DHC systems and the technologies and energy resources utilized within these systems - Analyzes the various methods used for harnessing energy to apply to DHC systems - Ideal resource for those interested in district cooling, teleheating, heat networks, distributed heating, thermal energy, cogeneration, combined heat and power, and CHP - Reviews the application of DHC systems in the field, including both the business model side and the planning needed to implement these systems




District Heating and Cooling Networks


Book Description

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.

Handbook of Low Temperature District Heating


Book Description

This book reviews the history and evolution of district heating networks, with a focus on current and future issues of the district heating sector. Novel developments in the field of low temperature district heating are studied, limitations for safe operation and avoidance of bacteria are considered, and the associated improved performance of the system with fewer network losses is presented. This book showcases how the evolution of district heating networks is linked to the increased use of renewables and de-carbonized heat sources with specific focus to waste heat streams and solar energy systems. Considering the novelty of these technologies, technological developments and funding schemes for these investments are still immature to some extent. For that reason, a comprehensive review of the main aspects of energy planning as well as district heating economics and financing schemes for large-scale investments in renewable energy systems for district energy systems is performed. In the light of digitalization, networks are increasingly monitored, allowing for a drastic change in the approach for network operation. This book also explores the increased digitization and monitoring of networks and how this impacts network operation. This book is of interest to engineers, academics and officials interested in energy systems, presenting readers with the key concepts and tools to adapt to the evolution of district heating into an integrated, digitized and higher performing system.










Current Trends and Future Developments on (Bio-) Membranes


Book Description

Current Trends and Future Developments in (Bio-) Membranes: Cogeneration Systems and Membrane Technology offers an exhaustive overview of the status of cogeneration systems as they relate to advanced membrane technologies for energy savings. The different options for cogeneration are analyzed, both for large (district) and small (residential) size units, with different primary fuels. Energy efficiency is reported and lifecycle analysis is carried out for all different options. The book outlines strategies for engineering development and process intensification of interest to both industrial and developing countries. Finally, the book includes three chapters on lifecycle analysis (LCA) and economic analysis. - Provides an overview of the interconnections between membrane technology and the systems used for the cogeneration of electricity, such as exhaust gas cleaning, carbon capture and sequestration, and low temperature fuel cells - Includes two different studies on LCA and a case study on economic analysis - Presents comprehensive reviews on various traditional cogeneration systems and compares them to alternative membrane-based technologies - Covers membrane based technologies and their application in co-generation systems - Addresses key issues on the introduction of process intensification in energy production




Microgrids and Local Energy Systems


Book Description

This book addresses important topical questions of microgrids and local energy systems. It begins with an investigation of the electrical protection of microgrids followed by a study of the power converters used and the utilization of multi-objective optimization for the selection of component ratings. Subsequent chapters address peer-to-peer energy trading in microgrids, local district heating and cooling systems, neighborhood generators used to supplement the utility electricity supplies in Iraq, and regulatory impediments to micro-wind generation in the United States.
