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. 000772315 588__ $$aDescription based on print version record. 000772315 650_0 $$aGeothermal engineering. 000772315 650_0 $$aGeothermal resources. 000772315 77608 $$iPrint version:$$tGeoenergy Modeling 2.$$d[Place of publication not identified] : Springer Verlag 2016$$z9783319450551$$w(OCoLC)954429244 000772315 830_0 $$aSpringerBriefs in energy.$$pComputational modeling of energy systems. 000772315 852__ $$bebk 000772315 85640 $$3SpringerLink$$uhttps://univsouthin.idm.oclc.org/login?url=http://link.springer.com/10.1007/978-3-319-45057-5$$zOnline Access$$91397441.1 000772315 909CO $$ooai:library.usi.edu:772315$$pGLOBAL_SET 000772315 980__ $$aEBOOK 000772315 980__ $$aBIB 000772315 982__ $$aEbook 000772315 983__ $$aOnline 000772315 994__ $$a92$$bISE
