PERFORMANCE MONITORING OF SELECT GROUND WATER HEAT PUMP INSTALLATIONS IN NORTH DAKOTA.

Author(s) : MATHEN D. V.

Summary

A GROUND WATER HEAT PUMP MONITORING PROGRAM WAS UNDERTAKEN TO OBTAIN THE ON-SITE SEASONAL PERFORMANCE FACTOR OF GROUND WATER SOURCE HEAT PUMPS AND TO PREDICT POTENTIAL EFFECTS OF LARGE-SCALE APPLICATION OF SUCH HEAT PUMPS ON AQUIFERS AND ON THE DEMAND LOADS OF ELECTRIC UTILITY COMPANIES. TEN HEAT PUMP SITES WERE MONITORED, PROVIDING A VARIATION IN SYSTEM CONFIGURATION, GEOGRAPHICAL LOCATION, WELL DEPTH, AND WATER TEMPERATURE AND DISPOSAL METHODS. RECORDS OF THERMAL ENERGY USAGE, WATER REQUIREMENTS, ELECTRICAL ENERGY CONSUMPTION, INLET WELL WATER TEMPERATURE, AND OPERATING PROBLEMS WERE MAINTAINED. THE HEAT PUMP PERFORMANCE LEVELS APPEAR TO BEOPERATING WITHIN THE RANGES SPECIFIED BY THE HEAT PUMP MANUFACTURERS, WITH AN APPROXIMATE 50% SAVINGS OVER ELECTRIC-RESISTANCE HEATING SYSTEMS. ENERGY SAVINGS OF GROUND WATER HEAT PUMPS OVER CONVENTIONAL AIR-TO-AIR UNITS IS HIGHLY DEPENDENT ON THE PARASITIC ENERGY REQUIREMENTS OF THE GROUND WATER HEAT PUMP SYSTEM.
