Available in PDF, EPUB and Kindle. Book excerpt: Small and micro combined heat and power (CHP) systems are a form of cogeneration technology suitable for domestic and community buildings, commercial establishments and industrial facilities, as well as local heat networks. One of the benefits of using cogeneration plant is a vastly improved energy efficiency: in some cases achieving up to 80–90% systems efficiency, whereas small-scale electricity production is typically at well below 40% efficiency, using the same amount of fuel. This higher efficiency affords users greater energy security and increased long-term sustainability of energy resources, while lower overall emissions levels also contribute to an improved environmental performance.Small and micro combined heat and power (CHP) systems provides a systematic and comprehensive review of the technological and practical developments of small and micro CHP systems.Part one opens with reviews of small and micro CHP systems and their techno-economic and performance assessment, as well as their integration into distributed energy systems and their increasing utilisation of biomass fuels.

Book Synopsis Energy Model of an Air Source Heat Pump to Explore Performance Improvements under Cold Conditions: A Python Framework: Preprint by :
Download or read book Energy Model of an Air Source Heat Pump to Explore Performance Improvements under Cold Conditions: A Python Framework: Preprint written by and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Replacing combustion appliances with heat pumps can be part of a strategy to electrify buildings. When their electricity is supplied by renewables, the adoption of heat pumps for space heating may help curb the carbon dioxide emissions inherent to traditional heating systems that burn natural gas or coal. When operating in very cold climates, however, heat pump performance deteriorates, sometimes requiring backup heating supplied by electric resistances or other sources to continue to function. To avoid the use of electric resistances, complementary technologies, like thermal energy storage, solar collectors, or alternative refrigerants, have been explored in recent years. In this study, we present an open-source Python-based numerical model developed to evaluate the annual hourly performance of an air source heat pump (ASHP) operating in the USA. Simulation results include coefficient of performance and heating capacity. The model, validated with experimental results, will be employed in the future to investigate the feasibility of integrating thermal energy storage and other technologies into ASHPs operating in cold climates.

Book excerpt: New inverter-driven ASHPs are gaining ground in colder climates. These systems operate at sub-zero temperatures without the use of electric resistance backup. There are still uncertainties, however, about cold-climate capacity and efficiency in cold weather and questions such as measuring: power consumption, supply, return, and outdoor air temperatures, and air flow through the indoor fan coil. CARB observed a wide range of operating efficiencies and outputs from site to site. Maximum capacities were found to be generally in line with manufacturer's claims as outdoor temperatures fell to -10 degrees F. The reasons for the wide range in heating performance likely include: low indoor air flow rates, poor placement of outdoor units, relatively high return air temperatures, thermostat set back, integration with existing heating systems, and occupants limiting indoor fan speed. Even with lower efficiencies than published in other studies, most of the heat pumps here still provide heat at lower cost than oil, propane, or certainly electric resistance systems.
Book Synopsis Sustainable Development for Engineers by : Karel Mulder
Download or read book Sustainable Development for Engineers written by Karel Mulder and published by Routledge. This book was released on 2017-09-08 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is crucial that engineers – from students to those already practising – have a deep understanding of the environmental threats facing the world, if they are to become part of the solution and not the problem. Is there a way to reconcile modern lifestyles with the compelling need for change? Could new improved technologies play a key role? If great leaps in the environmental efficiency of technologies are needed, can they be produced? Engineers are in a privileged and hugely influential position to innovate, design and build a sustainable future. But are they engaged or uninterested? Are they knowledgeable or ignorant? This book has been developed by a number of committed educators in European engineering departments under the leadership of Delft University of Technology and the Technical University of Catalunya to meet the perceived gap between what engineers know and what they should know in relation to sustainable development. The University of Delft decided as long ago as 1998 that all of its engineering graduates, working towards careers as designers, managers or researchers, should be prepared for the challenge of sustainable development and, as such, should leave university able to make sustainable development operational in their designs and daily practices. The huge amount of knowledge gathered on best-practice teaching for engineers is reflected in this book. The aim is to give engineering students a grounding in the challenge that sustainable development poses to the engineering profession, the contribution the engineer can make to attaining some of the societal and environmental goals of sustainability, and the barriers and pitfalls engineers will likely need to confront in their professional lives. Concise but comprehensive, the book examines the key tools, skills and techniques that can be used in engineering design and management to ensure that whole-life costs and impacts of engineering schemes are addressed at every stage of planning, implementation and disposal. The book also aims to demonstrate through real-life examples the tangible benefits that have already been achieved in many engineering projects, and to highlight how real improvements can be, and are being, made. Each chapter ends with a series of questions and exercises for the student to undertake. Sustainable Development for Engineers will be essential reading for all engineers and scientists concerned with sustainable development. In particular, it provides key reading and learning materials for undergraduate and postgraduate students reading environmental, chemical, civil or mechanical engineering, manufacturing and design, environmental science, green chemistry and environmental management.

Book Synopsis Nordsyn study on air-to-water heat pumps in humid Nordic climate by : Stignor, Caroline Haglund
Download or read book Nordsyn study on air-to-water heat pumps in humid Nordic climate written by Stignor, Caroline Haglund and published by Nordic Council of Ministers. This book was released on 2019-05-03 with total page 113 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study presented in this report has been performed for Nordsyn sponsored by the Nordic Council of Ministers. The aim of this study was to analyse if the information given on the energy labels of air-to-water heat pumps give consumers in Nordic countries sufficient information on energy performance. When comparing results from field measurements to declared values, it shows the declared values are usually better than the field data, especially in countries with humid climate. There could be several reasons for this deviation as non-optimal installations, bypass of control systems, old field data etc. The suspicion that the deviation is due to that the standard tests do not take humidity sufficiently into account could not be proved nor fully dismissed. Recommendations are given on how this could be further investigated, including field measurements in Nordic countries.
