Book Description
Seminar paper from the year 2021 in the subject Engineering - Power Engineering, grade: 1,3, Technical University of Munich, language: English, abstract: In this paper, the principle of heat pumps will be looked at and discussed more in detail. Heat pumps can play an important role in the transformation towards reducing greenhouse gas emissions and energy consumption, due to their ability to lift low-grade environmental heat with power to a temperature level useful in buildings. They are efficient in providing heat when implemented correctly and can also provide demand response. Thus, heat pumps are able to provide, compared to other heating systems, significant carbon savings that are even expected to rise further in the future. Reducing greenhouse gas emissions and energy consumption poses one of the major issues that has to be dealt with at present. National and international climate change objectives demand a significant reduction in all sectors Along with the increasing expectations of reducing greenhouse gas emissions, these global targets are causing a change in our energy system. The demand for energy-efficient and cost-effective systems have risen due primarily to dwindling resources causing increasing energy costs. To deal with these issues, the focus shifts more and more towards phasing out fossil fuels and replacing them with electrical energy systems powered by renewable intermittent energy sources, such as sun and wind, to decrease our reliance on fossil fuels. One way to heat buildings more efficiently is the use of a heat pump. Heat pumps have become popular in Germany, by now, over 1 million have been implemented.

Book Description
Advances in Ground-Source Heat Pump Systems relates the latest information on source heat pumps (GSHPs), the types of heating and/or cooling systems that transfer heat from, or to, the ground, or, less commonly, a body of water. As one of the fastest growing renewable energy technologies, they are amongst the most energy efficient systems for space heating, cooling, and hot water production, with significant potential for a reduction in building carbon emissions. The book provides an authoritative overview of developments in closed loop GSHP systems, surface water, open loop systems, and related thermal energy storage systems, addressing the different technologies and component methods of analysis and optimization, among other subjects. Chapters on building integration and hybrid systems complete the volume. Provides the geological aspects and building integration covered together in one convenient volume Includes chapters on hybrid systems Presents carefully selected chapters that cover areas in which there is significant ongoing research Addresses geothermal heat pumps in both heating and cooling modes

Book Description
It has long been recognized that realizing the potential for energy conservation and diversification by using heat pumps offers considerable benefits to the environment. Important work on more efficient and ozone-friendly working fluids will further enhance the case for greater support of heat pump research. This book contains the Proceedings of the Third International Energy Agency Conference held in Tokyo in March 1990. The main theme of the Conference, 'Heat Pumps - Solving Energy and Environmental Challenges', is explained in great depth, covering not only technical characteristics but economic factors and the role of government and other bodies in promoting research, and the uses of all types of heat pumps are also fully considered. As well as publishing the papers presented at the meeting, the book also contains the extensive complementary poster sessions from the Conference.

Book Description
In recent years, heat pumps have emerged as a promising new form of technology with a relatively low environmental impact. Moreover, they have presented householders with an opportunity to reduce their heating bills. Heat pumps can heat a building by 'pumping' heat from either the ground or the air outside: an intriguing process which utilizes principles that are somewhat analogous to those employed in the domestic refrigerator. Armed with the practical information contained in these pages, homeowners will have the necessary knowledge to take advantage of this potentially low-carbon technology to heat their properties.Describes what a heat pump is, how it works, the different methods of pumping heat and the importance of an appropriate and well-planned installation. Examines the air, the ground and water as sources of heat and explains how to make an informed choice. Considers the all-important subject of distributing the heat through radiators or through an under-floor system. Covers hot water production and delivery to the taps. Outlines environmental and financial issues associated with heat pumps. Dispels some common misconceptions and presents a number of case studies. Essential reading for all those householders who are considering installing heat pumps in order to heat their homes in a more eco-friendly and efficient way. Aimed at those homeowners who wish to do some of the work themselves or who wish to shadow sub-contractors. A useful reference tool for architects, plumbers, heating engineers, builders and students. Superbly illustrated with 155 colour photographs and diagrams by Gavin D J Harper. John Cantor is a heat pump engineer, inspector and consultant and has written many articles on the subject. Gavin D J Harper is a member of the Institute of Engineering and Technology.

Book Description
The text describes the main features of currently available heat pumps, focusing on system operation and interactions with external heat sources. In fact, before choosing a heat pump, several aspects must be assessed in detail: the actual climate of the installation site, the building’s energy requirements, the heating system, the type of operation etc. After discussing the general working principles, the book describes the main components of compression machines – for EHPs, GHPs and CO2 heat pumps. It then addresses absorption heat pumps and provides additional details on the behavior of two-fluid mixtures. The book presents a performance comparison for the different types, helping designers choose the right one for their needs, and discusses the main refrigerants. Notes on helpful additional literature, websites and videos, also concerning relevant European regulations, round out the coverage. This book will be of interest to all engineers and technicians whose work involves heat pumps. It will also benefit students in energy engineering degree programs who want to deepen their understanding of heat pumps.

Book Description
This book contains the texts of the lectures which were givenat the Nato Advanced Study Institute on Advanced Heat Pumns which was heldat Espinho, Portugal in September 1980. Aprevious NATO Advanced Study Institute on the topic of heat pumps had been held in 1975. The significance of heat pumps with respect to energy conservation was the main topic of this Institute. In 1980it was felt that considerable research had to be done in order to be able to produce more energy efficient, less costly and more widely ap~licableheat ~umos. This requires a good understanding of the functioning of the types of heat pumps available. The simultaneous coverage of the basic funda mentals of heat pumps of different drive in one lecture series therefore was the goal of the 1980 Advanced Study Institute. Only a few lectures were devoted to heat pump applications. The lectures on heat pump applications were intended to ~ive only a short overview. They were supplemented by lectures on the latest developments on vapour compression as well as sorption systems.
