HEAT TRANSFER, PRESSURE DROP, AND MASS LEAKAGE IN REVERSING VALVES: CHARACTERIZING PARAMETERS.

Author(s) : DAMASCENO G.

Summary

A STUDY TO COMPARE THE PERFORMANCE OF SEVERAL TYPES AND MAKES OF REVERSING VALVES AS USED INHEAT PUMP SYSTEMS IS PRESENTED. THE PARAMETERS ADDRESS: (1) MASS LEAKAGE FROM THE DISCHARGE, (2) (HIGH PRESSURE) TO THE SUCTION SIDE (LOW PRESSURE), (3) INTERNAL HEAT LOSS AND EXTERNAL HEAT LOSS FROM THE BODY OF THE REVERSING VALVE TO THE AMBIENT, AND (4) PRESSURE DROPS. TESTS WERE PERFORMED IN TWO DIFFERENT SETUPS: ONE USED TO MEASURE MASS LEAKAGE AND THE OTHER FOR HEAT LOSSES AND PRESSURE DROPS.
