MEASURING THE CONCENTRATION OF A FLOWING OIL-REFRIGERANT MIXTURE: INSTRUMENT TEST FACILITY AND INITIAL RESULTS.

Author(s) : BAUSTIAN J. J., PATE M. B., BERGLES A. E.

Summary

A REFRIGERANT FLOW LOOP FOR THE EVALUATION AND CALIBRATION OF OIL CONCENTRATION SENSORS IS PRESENTED. CAPABILITIES OF THE FLOW LOOP ARE DEMONSTRATED WITH THE RESULTS OF AN INITIAL SERIES OF EXPERIMENTS USING MIXTURES OF R22 AND A NAPHTHENIC MINERAL OIL. THESE EXPERIMENTS PROVIDED PRELIMINARY DATA ON THE PERFORMANCE OF 2 POTENTIAL OIL CONCENTRATION SENSORS: A VIBRATING U-TUBE DENSIMETER AND AN ULTRASONIC ACOUSTIC VELOCITY SENSOR. EXPERIMENTALLY DETERMINED VALUES OF SPECIFIC GRAVITY AND ACOUSTIC VELOCITY IN THE FLOWING OIL-REFRIGERANT MIXTURES ARE INCLUDED.
