TWO-PHASE REFRIGERANT FLOW MEASUREMENT WITH LIQUID AND VAPOUR SEPARATION TECHNIQUE.

Author(s) : MEI V. C.

Summary

CONVENTIONAL TWO-PHASE FLOW MEASURING TECHNIQUES ARE EITHER TOO EXPENSIVE OR HAVE LOW ACCURACY OR BOTH. THE PAPER PRESENTS AN ACCURATE MEASUREMENT IN WHICH THE LIQUID AND VAPOUR ARE SEPARATED AND THE FLOW RATE OF EACH PHASE IS MEASURED WITH CONVENTIONAL FLOW METERS. A LOW-COST AND LOW-PRESSURE DROP SEPARATOR WAS BUILT AND TESTED ON A SPLIT HEAT PUMP SYSTEM. THE RESULTS INDICATE THAT THE SEPARATOR WORKED AS EXPECTED BY SEPARATING THE TWO-PHASE REFRIGERANT FOR VAPOUR QUALITY FROM 6.1 TO 14.7%, WITH REFRIGERANT PRESSURE DROP RANGING FROM 14 TO 35 KILOPASCALS IN MOST TESTS.
