Summary

DESCRIBES HIGH-EFFICIENCY GROUND HEAT EXCHANGER DEVELOPED FOR USE WITH GROUND-SOURCE HEAT PUMPS. THE EXCHANGER IS MADE OF COPPER TUBING SHAPED IN THE FORM OF A SPIRAL, WHICH CAN BE INSTALLED IN A VERTICAL BOREHOLE BACKFILLED WITH SAND. STATES THAT THERMAL PERFORMANCE OF A FULL-SCALE PROTOTYPE INDICATES THAT THIS TYPE OF HEAT EXCHANGER CAN ACHIEVE VERY HIGH HEAT EXTRACTION RATES IF SUBFREEZING OPERATING TEMPERATURES ARE USED. FOR MOST SOIL TYPES FREEZING AND THAWING ARE NOT A PROBLEM. (INT. BUILD. SERV. ABSTR., GB., 24, N 6, 1989/11-12, 89-01731.
