WebNov 19, 2024 · Closed Loop Geothermal Systems There are 3 types of closed loop geothermal systems: vertical, horizontal, and pond / lake. Because pond/lake loops require having a water source on the property, … WebThe closed-loop systems use a buried earth coil as the ground heat exchanger (GHE) through which a heat transfer fluid, typically an antifreeze solution, is circulated. The GHE, installed either vertically in borings or horizontally in trenches, exchanges heat with the ground ( Fig. 1 ). イファ女子大学 語学堂 寮
