摘要
Horizontal ground-coupled heat exchanger for geothermal systems is proposed. The exchanger includes sub-surface formation of not expensive special structure heat conductive stratum around conduit loops. Analytical and finite element modeling allowed estimating the new structure efficiency. The proposed decision permits to increase by 2-3 times the transmitted heat power of the exchanger and correspondently to reduce the required pipe length and land area. The underground loop must be sized to meet the peak thermal power load. The proposed exchanger structure may fill simply this requirement, because at relatively short-term operation the efficiency of the proposed structure is even higher and reaches increasing by 2.5-4 times in dependence on climate zone.
