Since direct exchange technology is not new and is very efficient, why haven the larger heating/cooling companies pursued the technology?
There are several answers to this question. • Larger companies are focused on traditional designs and are generally not aware of the newer, reverse-cycle, direct exchange (DX) systems, which have only been marketed on a very limited basis for about 15 years. • Older, first generation, horizontal field, DX technology required a great deal of land area for system installation, which severally limited the available market and hindered general market acceptance (the ETA design only requires one to three 6 inch diameter holes for a two ton through a five ton system). • There were legitimate concerns over lack of compressor oil return (and resulting premature compressor failure) in older, first generation DX horizontal field system designs, including a few relatively shallow (50′ to 100′ deep) vertical designs. ETA has totally solved and eliminated the oil return concern by additing of a patent-pending oil separator component that prevents oil from traveling into the sub-surface tubing. • Th
