INFLUENCE OF OIL INJECTION AND PRESSURE RATIO ON SINGLE SCREW PERFORMANCES AT HIGH TEMPERATURE.

Author(s) : BLAISE J. C., DUTTO T.

Summary

A MONO-SCREW COMPRESSOR OPERATING AT 370 K (97 DEG C) CONDENSING TEMPERATURE FOR HEAT-PUMP APPLICATION WITH R142B WAS TESTED FOR OVER 1,000 HOURS WITH VARIOUS RATES OF OIL INJECTION AND PRESSURE RATIOS. INCREASES IN THE SEALING OIL FLOW GAVE INCREASES IN VOLUMETRIC EFFICIENCY WHICHDECREASED SLIGHTLY WITH INCREASED BEARING OIL FLOW DUE TO INCREASES OF RELEASED REFRIGERANT. DECREASES IN EFFICIENCY WERE OBTAINED WHEN PRESSURE RATIO DID NOT CORRESPOND TO THE COMPRESSOR VOLUME RATIO. D.W.H.
