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

Ground-Source Heat Pumps presents the theory and some of the most recent advances of GSHPs and their implementation in the heating/cooling system of buildings. The authors explore the thermodynamic cycle with calculation, operation regimes and economic indicators and GHG emissions of a vapor compression heat pump. They go on to examine substitution strategies of non-ecological refrigerants and types of compressors and heat pumps, before delving into the different GSHP systems, as well as their compared economic, energy and environmental performances using classical and optimized adjustment for various operating modes. Surface water heat pumps and ground water heat pumps are covered, and special focus is given to both vertical and horizontal ground-coupled heat pump systems, for which modelling and simulation is discussed, and experimental systems are described. Due to its advanced approach to the subject, this book will be especially valuable for researchers, graduate students and academics, and as reference for engineers and specialists in the varied domains of building services. Explores fundamentals and state-of-the-art research, including ground-coupled heat pump (GCHP) systems. Includes performance assessment and comparison for different types of GSHP, numerical simulation models, practical applications of GSHPs with details on the renewable energy integration, information on refrigerants, and economic analysis.

Geothermal Heating and Cooling is a complete revision of Ground-Source Heat Pumps: Design of Geothermal Systems for Commercial and Institutional Buildings, which is recognized as the primary reference for nonresidential ground-source heat pump (GSHP) installations. This new work takes advantage of the many lessons learned since the time of the original publication, when GSHPs were primarily residential applications. Many improvements have evolved, and performance data, both positive and negative, is now available to guide the development of best practices. This essential guide for HVAC design engineers, design-build contractors, GSHP subcontractors, and energy/construction managers also provides building owners and architects with insights into characteristics of quality engineering firms and the information that should be provided by design firms competing for GSHP projects.This revision draws on new ASHRAE and industry research in critical areas, as well as measured data from long-term installations and optimized installation practices used by high-production GSHP contractors. Nearly all chapters and appendices were completely rewritten, and they include coverage of closed-loop ground (ground-coupled), groundwater, and surface-water systems plus GSHP equipment and piping. Additional information on site characterization has been added, including a new hydrogeological chapter. Another new chapter contains results of recent field studies, energy and demand characteristics, and updated information to optimize GSHP system cost. While other publications deal primarily with ground-coupled heat pumps, this text includes detailed coverage of groundwater, surface-water, and GSHP costs.Tables, graphs, and equations are provided in both Inch-Pound (I-P) and International System (SI) units. As a bonus, supplemental Microsoft® Excel® macro-enabled spreadsheets for a variety of GSHP calculations accompany the text.

With ground source heat pump systems becoming an increasing focus in the building energy efficiency sector, fully understanding their behavior is key. For systems such as these, computer simulation is typically performed to design them, or to examine their potential energy performance. Therefore, having detailed simulations that take into account all relevant behaviors of these systems is of the utmost importance.

Increasing energy demand and environmental pollution in United States has been led toward using renewable energy sources over recent decades. Ground-source heat pump systems are one of the promising new energy technologies that have shown rapid increase in usage over the past ten years in the United States. Low efficiency and lack of design guidelines are still the limits of GSHP systems. This paper studies the effects of heat conduction in boreholes used in geothermal heat pump systems. The purpose of this study was to determine the temperature distribution in ground source heat pump system by studying and modeling the ground bore and compare it to proposed design system based on advanced heat transfer and finite elements techniques. Solid Works software, version 2010 is utilized to simulate and calculate each system by using finite elements methods. Findings and Conclusions: The ground loop heat exchanger model was successfully implemented in the Solid Works program. The primary objective of this study is: examine effects of ground-boreholes on closed-loop GSHP systems, develop a design and simulation tool for modeling the performance of a ground Loop Heat Exchanger on closed-loop GSHP systems, and comparing the effects of boreholes different configuration in energy distribution on closed-loop GSHP systems. Simulation result based on the mathematical background which is presented in chapter 2 and 3, have an excellent agreement with the purpose of this thesis and showed the significant energy saving. The solid and hollow cylindrical bores simulate in steady state and transient cases. The results demonstrate around 5.8 % saving in energy consumption by applying a proposed system.
