Summary

THE PAPER IS CONCERNED WITH A ROLLING PISTON TYPE ROTARY COMPRESSOR FOR AIR CONDITIONING USE. THE LEAKAGE THROUGH CLEARANCES BETWEEN ROLLING PISTON FACES AND CYLINDER HEAD WALLS IS ANALYSED THEORETICALLY AND EXPERIMENTALLY. THE LEAKAGE DECREASES VOLUMETRIC EFFICIENCY AND INCREASES POWER CONSUMPTION OF THE COMPRESSOR. FRICTION LOSSES AT THE VANE TIP AND SIDES AND AT THE ROLLING PISTON BEARING ARE ANALYSED TAKING ACCOUNT OF THE KINEMATICS OF THE COMPRESSOR. IT IS INDICATED THAT THE SHORT LENGTH/DIAMETER CONFIGURATION OF THE CYLINDER IS FAVOURABLE TO DECREASE TOTAL LOSS BUT THE REVERSE IS DESIRABLE TO ACHIEVE MAXIMUM RELIABILITY OF THE COMPRESSOR.
