ON EXPERIMENTAL ERRORS IN P-V DIAGRAMS.

Author(s) : KIM J., SOEDEL W.

Summary

IT IS COMMON PRACTICE TO FOLD PRESSURE-TIME DIAGRAMS OF COMPRESSORS INTO PRESSURE-VOLUME DIAGRAMS BECAUSE THE LATTER ARE OF SPECIAL THERMODYNAMIC SIGNIFICANCE. IT WAS FOUND THAT EVEN A SMALL MEASUREMENT ERROR OF THE TOP DEAD CENTER POSITION MAY CHANGE THE PRESSURE-VOLUME DIAGRAM SIGNIFICANTLY. ALSO, THE INFLUENCE OF PRESSURE TRANSDUCER CALIBRATION ERROR WAS INVESTIGATED. ERRORS ASSOCIATED WITH THE PRESENT METHOD OF LOCATING SUCTION AND DISCHARGE PRESSURES WITH THE AID OF VALVE OPENING DATA IS DISCUSSED.
