DESIGN OF WATER-TO-AIR HEAT PUMPS WITH HIGH COOLING EFFICIENCY FOR GROUND-COUPLED APPLICATIONS.

Author(s) : KAVANAUGH S. P.

Summary

UNITARY WATER-TO-AIR HEAT PUMPS HAVE OUTSTANDING AIR-AND WATER-HEATING CAPABILITIES. THE PAPER PRESENTS SEVERAL PERFORMANCE IMPROVEMENT POSSIBILITIES WITH UNITARY WATER-TO-AIR HEAT PUMPS. THE DESIGN PARAMETERS OF TWO 2.5 TON (8.8 KILOWATTS) HEAT PUMPS ARE PRESENTED. DESIGN COOLING EFFICIENCIES IN THE 14.0 TO 15.0 BTU/WH (COP = 4.1 TO 4.4) RANGE ARE PREDICTED WITH RECIPROCATING COMPRESSORS. SEASONAL EFFICIENCIES SHOULD BE 15% HIGHER. AN ADDITIONAL 10% IMPROVEMENT IS POSSIBLE WITH SCROLL COMPRESSORS AND IMPROVED INDOOR FAN MOTORS.
