Thermal Performance of Borehole Heat Exchangers
An important issue in the design of systems using borehole heat exchangers is to find costeffective methods to construct the borehole heat exchanger so that heat can be injected or extracted from the ground without excessive temperature differences between the heat carrier fluid and the surrounding ground. This paper presents an overview of experiences and current activities in this field.
متن کاملPredicting thermal–hydraulic performances in compact heat exchangers by support vector regression
An alternative model using support vector regression (SVR) based on dynamically optimized search technique with k-fold cross-validation, was proposed to predict the thermal–hydraulic performance of compact heat exchangers (CHEs). 48 experimental data points from the author’s own study were used in the present work. The performance of SVR with different regularization parameter c and kernel para...
متن کاملEffectiveness of Thermal Sanitization of Piggery Slurry Using Heat Exchangers
Livestock agriculture dominated by pig rearing is responsible for the production large volumes of wastes. Across the European Union there are over 151 million pigs that produce 300 million tonnes of slurry annually. Furthermore, intensive production linked to certain regions, leads to zones of nutrient excess where available land for land spreading is insufficient. However, even if the environm...
متن کاملThermal Efficiency Comparison of Borehole Heat Exchangers with Different Drillhole Diameters
Thermal efficiency of borehole heat exchangers (BHE) is of crucial importance for the design and optimization of ground source heat pump (GSHP) system. This paper investigates thermal efficiency of a BHE with three drillhole diameters: 121 mm, 165 mm and 180 mm. The BHE was installed in a GSHP system of an office building located in Nuremberg, Germany. Thermal properties and hydraulic propertie...
متن کاملTitle : 2 D THERMAL RESISTANCE OF PILE HEAT EXCHANGERS
Structural foundation piles are being used increasingly as heat exchangers to provide renewable heat for new buildings. To design such energy systems a steady state is assumed within the pile, which is conventionally characterised by constant thermal resistance. However, there has been little research regarding pile resistance and there are few published case studies. Numerical modelling result...
