Download or read book Geoenergy Modeling II written by Haibing Shao and published by Springer. This book was released on 2016-10-06 with total page 99 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is dedicated to the numerical modeling of shallow geothermal systems. The utilization of shallow geothermal energy involves the integration of multiple Borehole Heat Exchangers (BHE) with Ground Source Heat Pump (GSHP) systems to provide heating and cooling. The modeling practices explained in this book can improve the efficiency of these increasingly common systems. The book begins by explaining the basic theory of heat transport processes in man-made as well as natural media. . These techniques are then applied to the simulation of borehole heat exchangers and their interaction with the surrounding soil. The numerical and analytical models are verified against analytical solutions and measured data from a Thermal Response Test, and finally, a real test site is analyzed through the model and discussed with regard to BHE and GSHP system design and optimization.

Download or read book Residential Geothermal Systems written by John Stojanowski and published by Pangea Publications LLC. This book was released on 2011-03-01 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: NEW EXPANDED EDITION with color illustrations and spacious 8.5 x 8.5 format adds detailed descriptions of the components of the heat pump, open loops systems and important decisions that the homeowner must make. Interest in residential geothermal systems has grown as more people realize they can replace their fossil-fuel heating system with one that is three to five times more efficient and doesn't require a chimney to exhaust noxious fumes. Currently in the USA there is a federal 30% tax credit that applies to the total installation cost. These newer, safer systems provide heating as well as cooling simply by transferring heat between the home and the ground or a nearby body of water. Since this is a relatively new technology, the number of experienced installers is limited, but growing. Therefore, there is a burden on homeowners interested in installing one of these systems to absorb as much information about residential geothermal systems as possible. This book was written specifically to meet that need as well as to help HVAC professionals who are new to residential geothermal systems. Readers will learn how heat pumps are able to extract heat from relatively low temperature water circulating in ground loops and raise it to a temperature high enough to heat a home. They will also learn how to estimate the size of the heat pump required and the ground loop size as well for straight 2-pipe, 4-pipe, 6-pipe and Slinky loop configurations. This is important in order to verify that the installer correctly sizes the system. An incorrectly sized system will result in an unhappy homeowner. Both horizontal and vertical loop systems, for GX and DX, are covered. Some of the technical issues that are addressed include: Loop water flow rates and Reynolds Number, heat of extraction/rejection, heating capacity, desuperheater setup, open-loop/closed-loop, SCW, pond loops, DX, Manual-J, COP. The final chapter consists of a set of flowcharts guiding the homeowner to ask the pertinent questions needed for a successful installation.

Download or read book Commercial Program Development for a Ground Loop Geothermal System written by Paul A. Gross (II) and published by . This book was released on 2011 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of the earth's thermal energy to heat and cool building space is nothing new; however, the heat transfer approximations used in modeling geothermal systems, leave uncertainty and lead to over sizing. The present work is part of a Wright State effort to improve the computer modeling tools used to simulate ground loop geothermal heating and cooling systems. The modern computer processor has equipped us with the computation speed to use a finite volume technique to solve the unsteady heat equation with hourly time steps for multi-year analyses in multiple spatial dimensions. Thus we feel there is more need to use approximate heat transfer solution techniques to model geothermal heating and cooling systems. As part of a DOE funded project Wright State has been developing a ground loop geothermal computer modeling tool that uses a detailed heat transfer model based on the governing differential energy equation. This tool is meant to be more physically detailed and accurate than current commercial ground loop geothermal computer codes. The Wright State code allows the geothermal designer to optimize the system using a number of outputs including temperature field outputs, existing fluid temperature plots, heat exchange plots, and even a histogram of the COP data. Careful attention to the algorithm speed allows for multi-year simulations with minimal computation cost. Once the thermal and heat transfer computations are complete, a payback period calculator can compare any conventional heating and cooling system to the designed geothermal system and payback periods are displayed. The work being presented as part of this thesis deals with five issues that were required to make the Wright State geothermal computer code a reality. The five aspects of this modeling tool addressed by this thesis work are: energy load calculations, GUI (graphical user interface) development, turbulence model development, heat pump model development, and two-dimensional numerical grid development. The energy load, or heating and cooling load, calculations are handled using the sophisticated DOE program called EnergyPlus. This thesis work developed a technique for coupling EnergyPlus to the Wright State geothermal code and devising a way for novice users to obtain energy loads quickly and easily, while still allowing expert users to utilize the full strength of EnergyPlus. The GUI for the Wright State computer program was developed with the novice and expert users in mind. The GUI offers ease of use while maintaining the ability for the expert users to setup unique designs for simulation. A unique way of modeling the effects of turbulent flow in the ground tube has allowed the Wright State code to maintain low computation times, while having small errors for a wide range of Reynolds numbers. To make the Wright State ground loop computer model more complete, a heat pump was developed as part of this work. The heat pump model uses the performance characteristics of commercial heat pumps to determine the performance of the geothermal system. The energy transport in the fluid is determined and used to select one of eighteen water-to-air heat pumps that calculate hourly COP's for all system conditions. The calculated heat pump efficiencies are used in an energy balance with hourly building loads to calculate the next iteration's bulk temperature entering the ground loop. Additional details are provided in this thesis on each of these five, important, computer modeling issues.

Book excerpt: This comprehensive compilation of DOE documents provides unique and practical information about geothermal heat pumps, including small geothermal systems and DIY systems. Contents: Chapter 1: Small Geothermal Systems: A Guide For The Do-It-Yourselfer * Chapter 2: Using The Earth To Heat and Cool Buildings * Chapter 3: An Information Survival Kit For The Prospective Geothermal Heat Pump Owner * Chapter 4: Success Stories of the Geothermal Energy Program * Chapter 5: Ground-Source Heat Pumps: Overview of Market Status, Barriers to Adoption, and Options for Overcoming Barriers A heat pump-like an air conditioner or refrigerator-moves heat from one place to another. In the summer, a geothermal heat pump (GHP) operating in a cooling mode lowers indoor temperatures by transferring heat from inside a building to the ground outside or below it. Unlike an air conditioner, though, a heat pump's process can be reversed. In the winter, a GHP extracts heat from the ground and transfers it inside. Also, the GHP can use waste heat from summer air-conditioning to provide virtually free hot-water heating. The energy value of the heat moved is typically more than three times the electricity used in the transfer process. GHPs are efficient and require no backup heat because the earth stays at a relatively moderate temperature throughout the year. A GHP system has three major components: a ground loop (buried piping system), the heat pump itself (inside the house), and a heating and cooling distribution system. There are two main types of GHP systems. The earth-coupled (or closed-loop) GHP uses sealed horizontal or vertical pipes as heat exchangers through which water, or water and antifreeze, transfer heat to or from the ground. The second type, the water-source (or open-loop) GHP, pumps water from a well or other source to the heat exchanger, then back to the source. Because of their versatility, earth-coupled systems dominate the GHP market. Typical loop installations for the earth-coupled systems are expected to work for 50 years. More than 400,000 GHPs are operating in homes, schools, and commercial buildings in the United States. They are adaptable to virtually any kind of building; the Federal government has installed nearly 10,000 GHPs. Geothermal resources are available across the United States at varying depths, providing a ubiquitous buried treasure of domestic renewable energy. Enormous amounts of hydrothermal geothermal energy is available in the western United States, but theoretically, geothermal sources are available across the United States. The key to being able to use geothermal energy is to find a way to enhance geothermal systems lacking key natural characteristics. Natural geothermal systems depend on three factors to produce energy: heat, water, and permeability. While heat is present virtually everywhere at depth, water and permeability are less abundant. Geothermal technology is an attractive renewable resource because it can provide a constant source of renewable baseload electricity. While the sun and wind offer a large potential source of renewable energy that varies over time, geothermal technology is uninterruptible and can provide a stable baseload form of energy while diversifying the nation's renewable portfolio. Geothermal energy has low environmental risk and impact. When used with a closed-loop binary power plant, geothermal systems emit zero greenhouse gas emissions and have a near zero environmental risk or impact.
