ShareGROUND-COUPLED HEAT PUMP SYSTEM. EXPERIMENTAL RESULTS.
Author(s) : METZ P. D.
Summary
SINCE OCTOBER 1980, A SMALL HOUSE IN LONG ISLAND HAS BEEN HEATED AND COOLED BY A LIQUID-SOURCE HEAT PUMP USING A SHALLOW SERPENTINE EARTH COIL AS A HEAT SOURCE/SINK. THE HEAT PUMP USED IS A COMMERCIALLY AVAILABLE WATER-TO-AIR UNIT. THE EARTH COIL CONTAINS 155 M OF 4 CM MEDIUM-DENSITY POLYETHYLENE PIPE AND IS BURIED 1.2 M DEEP. AN ANTIFREEZE SOLUTION CONSISTING OF APPROXIMATELY 25% ETHYLENE GLYCOL IN WATER IS EMPLOYED TO PERMIT SUBFREEZING EARTH-COIL OPERATION.
