Summary

THE AUTHOR OUTLINES THE NEED FOR TWO-STAGE COMPRESSION IN LOW-TEMPERATURE REFRIGERATION. FOUR BASIC SYSTEMS OF INTERSTAGE COOLING FOR VAPOUR AND LIQUID ARE DISCUSSED, SUBCOOLING USING AN INTERSTAGE EVAPORATOR WITH OVERFEED FOR INTERSTAGE VAPOUR COOLING BY LIQUID INJECTION BEING PREFERRED. ITS MAIN ADVANTAGE OVER BUBBLE-TYPE INTERCOOLING, APART FROM SPACE SAVING, IS THAT NO COLLECTING POINT OCCURS FOR THE INTERSTAGE OIL. THE CHOICE BETWEEN TWO INDIVIDUAL SINGLE-STAGE COMPRESSORS AND AN INTEGRAL 2-STAGE MACHINE IS ARGUED, PREFERENCE BEING SUGGESTED FOR THE INTEGRAL MACHINE AT SMALLER DUTIES. D.W.H.
