DOWNLOAD EBOOKGeothermal or ground source heat pumps (GSHPs) are among the growing renewable energy technologies used for heating and cooling of buildings. However, little work has been done to investigate their geo-environmental effects within the subsurface. This research uses FEFLOW software, to simulate heat and mass transport for a vertical closed-loop GSHP system. Steady and transient flow and heat transport results for a multiple borehole system are presented which indicate long-term effects on ground temperature. Moreover, the impact of heat exchanged with the subsurface on contaminant transport and biodegradation processes is studied to evaluate the possibility of utilizing this heat as a remediation strategy. The results reveal that temperature changes caused by GSHP operation can significantly enhance biodegradation of hydrocarbon contaminants. For instance, elevated subsurface temperature resulted in 96% reduction in benzene concentration, from 0.306 to 0.011 mg.L-1, after one year of GSHP operation for an office building in Toronto.

DOWNLOAD EBOOKGround source heat pumps are a very successful renewable technology used in many countries, so why are they less popular in the UK? With the current focus on going green, and the environment being a 'hot topic' at the moment, it seems that ground source heat pumps have been overlooked in the UK. They clearly have the potential to greatly help the UK to reduce its environmental impact. This book looks into existing case studies of heat pumps in the UK to determine whether they should be widely installed in domestic properties. Different factors are considered such as financial viability, carbon dioxide emissions and running costs. The conclusion is that GSHP can greatly benefit the environment as well as the occupants.

DOWNLOAD EBOOKGround-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.

DOWNLOAD EBOOKThis book presents an overview of geothermal heating systems using ground source heat pumps in different countries. It evaluates the emissions and energy costs generated by the operation of low enthalpy geothermal systems, with heat pumps fed by different energy sources, and assesses, from an international point of view, those policies whose aim is a sustainable, low-carbon economy. The use of low-impact energy sources is gradually growing with the aim of reducing greenhouse gases emission and air pollution. The alternatives offered by geothermal systems are one of the key solutions for a future renewable development, enabling the electrification of heating systems and the use of biofuels. The book will be of interest to energy professionals and researchers.

DOWNLOAD EBOOKThe recommendations summarise the state of the art. Their aim is the proper exploitation of the ground for geothermal purposes without adversely affecting the ground or the groundwater on the one hand and the operation of the system and nearby buildings on the other. The recommendations should be used during consulting, design, installation and operation in order to achieve optimum and sustainable use of the ground at a specific location. Authorities responsible for supervising and approving projects can use the recommendations as a guide when taking decisions and making stipulations. The Geothermal Energy Study Group was set up in Bochum in 2004 and became the joint DGGV/DGGT study group in 2007. Some 20 specialists from universities, authorities and engineering consultants are active in the group and meet two or three times a year.
