A REFRIGERANT ENTHALPY METHOD FOR MEASURING REVERSING VALVE HEAT TRANSFER.

Author(s) : HARGRAVES D. P.

Summary

TECHNIQUES FOR MEASURING REFRIGERANT ENTHALPY AT FOUR STATIONS AROUND A REVERSING VALVE ARE DESCRIBED. A HEAT FLOW BALANCE IS USED TO CALCULATE HEAT FLOW CONDUCTED THROUGH THE VALVE MATERIALS OF CONSTRUCTION. AN ANALYTICAL METHOD FOR MINIMIZING THE EFFECTS OF INTERNAL LEAKAGE ON THE CALCULATED HEAT TRANSFER IS DEVELOPED. REFRIGERANT ENTHALPY CHANGE CAN BE AN ACCEPTABLE MEASURE OF REVERSING VALVE HEAT TRANSFER WITH INTERNAL LEAKAGE RATES CURRENTLY TYPICAL IN THE INDUSTRY.
