A unique approach to the study of geothermal energy systems This book takes a unique, holistic approach to the interdisciplinary study of geothermal energy systems, combining low, medium, and high temperature applications into a logical order. The emphasis is on the concept that all geothermal projects contain common elements of a "thermal energy reservoir" that must be properly designed and managed. The book is organized into four sections that examine geothermal systems: energy utilization from resource and site characterization; energy harnessing; energy conversion (heat pumps, direct uses,...

This work reviews and analyses design options used to assess the feasibility of a Ground Source Heat Pump (GSHP) to supply heating to twelve flats. Incentives for communal heating and renewable energy are examined, as are grants and schemes provided to assist uptake of GSHP systems. Four elements of GSHP system design are evaluated: heating load, pump size, borehole array and heat delivery system. The aim is to determine optimal design by minimising energy demand, land use, material use and project costs, whilst maximising system efficiency. Peak Load calculations and various borehole options ... [Read More]
