NATURAL GAS INTERNAL COMBUSTION ENGINE-DRIVEN HEAT PUMPS.

Author(s) : SHELTON S. V.

Summary

COMPARED TO CURRENT HIGH EFFICIENCY CONDENSING FURNACES, GAS HEAT PUMPS OFFER PRACTICALSAVINGS ON THE ORDER OF 50%. THE MOST MATURE CONCEPT AVAILABLE IS THE NATURAL GAS INTERNAL COMBUSTION ENGINE HEAT PUMP SYSTEM. SEVERAL HUNDREDS OF THESE SYSTEMS ARE OPERATING IN WESTERN EUROPE. ONLY ONE IS KNOWN IN THE US FOR SEVERAL YEARS, AND IT IS THE FOCUS OF THE PAPER. AN INTERNAL COMBUSTION ENGINE WATER-TO-WATER HEAT PUMP PACKAGE DESIGNED FOR HEATING ONLY WAS MODIFIED, INSTRUMENTED, AND INTEGRATED INTO A RESIDENTIAL CENTRAL AIR HEATING/COOLING SYSTEM TO PROVIDE TOTAL SPACE CONDITIONING FOR A 320 M2 RESIDENCE. THE RESULTING SEASONAL HEATING AND COOLING COEFFICIENTS OF PERFORMANCE WERE 14AN5ETL. THESE DEMONSTRATED FIELD EFFICIENCIES ARE APPROXIMATELY DOUBLE THOSE OF CONVENTIONAL GAS FURNACES AND APPROXIMATELY 50% HIGHER THAN THOSE OF CONVENTIONAL ABSORPTION AIR CONDITIONING.
