STEADY-STATE REFRIGERANT FLOW AND AIR FLOW CONTROL EXPERIMENTS FOR A CONTINUOUSLY VARIABLE SPEED AIR-TO-AIR HEAT PUMP.

Author(s) : MILLER W. A.

Summary

A CONTINUOUSLY VARIABLE SPEED, AIR-TO-AIR SPLIT-SYSTEM RESIDENTIAL HEAT PUMP OF NOMINAL 9.7 KILOWATT CAPACITY WAS INSTRUMENTED AND TESTED IN THE LABORATORY. THE COP, CAPACITY OF THE SYSTEM, AND COMPONENT EFFICIENCIES WERE MEASURED DURING STEADY-STATE HEATING-AND COOLING-MODE OPERATION. THE INDOOR BLOWER SPEED AND THE REFRIGERANT SUBCOOLING AT THE CONDENSER EXIT WERE VARIED AT DISCRETE COMPRESSOR SPEEDS TO DETERMINE THE BEST COP. HEATING-AND COOLING-MODE TEST RESULTS SHOWED A 10% IMPROVEMENT IN COP FOR OPERATION WITH A VARIABLE AREA THROTTLE AS COMPARED WITH A CAPILLARY TUBE THROTTLE.
