MEASURING THE CONCENTRATION OF A FLOWING OIL-REFRIGERANT MIXTURE WITH AN ACOUSTIC VELOCITY SENSOR.

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

Summary

AN ACOUSTIC VELOCITY SENSOR WAS CONSTRUCTED FOR THE MEASUREMENT OF OIL CONCENTRATION IN THE LIQUID LINE OF A REFRIGERATION SYSTEM. THE SENSOR WAS TESTED UNDER SIMULATED LIQUID-LINE CONDITIONS WITH R12-NAPHTHENIC OIL, R22-NAPHTHENIC OIL, AND R502-ALKYLBENZENE OIL MIXTURES IN CONCENTRATIONS OF 0 TO 30 WEIGHT-PERCENT. TEST TEMPERATURES IN THE SIMULATED LIQUID LINE RANGED FROM 294 TO 319 K (21 TO 46 DEG C) AT PRESSURES CORRESPONDING TO APPROXIMATELY 1.7 K (1.7 DEG C) SUBCOOLING. STATISTICAL ANALYSIS OF THE DATA SHOWED THAT THE ACOUSTIC VELOCITY SENSOR CAN BE USED WITH AN UNCERTAINTY OF ABOUT 1 WEIGHT-PERCENT OR LESS FOR NEARLY ALL OF THE TEST CONDITIONS.
