MONITORING OF RESIDENTIAL GROUNDWATER-SOURCE HEAT PUMPS IN THE NORTHEAST.

Author(s) : FREEDMAN G. M., DOUGALL R. S.

Summary

TWO GROUNDWATER HEAT PUMPS WERE INSTALLED IN EXISTING RESIDENCES IN CLIMATES OF MORE THAN 6,000 HEATING DEGREE-DAYS (DEG F). THEY REMOVE HEAT FROM SUPPLY WATER VIA A VAPOUR COMPRESSION REFRIGERATION CYCLE TO HEAT AIR IN A FORCED-AIR DISTRIBUTION SYSTEM. THEY WERE RETROFIT INTO FORCED-AIR FOSSIL-FUEL-FIRED HEATING SYSTEMS. ELECTRIC FURNACE UNITS WERE INSTALLED TO CONVENIENTLY MEASURE BACKUP HEAT REQUIREMENTS AND FOR CALIBRATION. BOTH UNITS EXHIBITED HEATING SEASON COP LESS THAN COPS PUBLISHED BY THE MANUFACTURERS. NO SIGNIFICANT SUPPLEMENTAL HEAT WAS REQUIRED BY EITHER SYSTEM.
