The lower BHE thermal resistance can be achieved by using thermally enhanced pipes and grout, increasing the surface area of the loop, and locating the legs proximal to the borehole [16]. Globally, GSHPs represent 71.6% of all direct-use geothermal installations and 59.2% of direct-use ...
Water will begin to condense on the surface of a cooling coil at the point where the surface temperature equals the dew point of the entering air and, in order to calculate the heat transfer through the cooling coil, the relative areas associated with the wet and dry portions of the coil ...
