Summary

THE POSSIBILITY OF ENERGY SAVING BY SPEED CONTROL OF THE REFRIGERATION COMPRESSOR. SPEEDCONTROL IS COMPARED WITH SUCTION VALVE LIFTING. THE SPEED CONTROL IS ONLY DONE IN TWO STEPS WITH A TWO-SPEED MOTOR. THE ENERGY SAVING AT 50% CAPACITY IS 35% COMPARED TO VALVE LIFTING. THE EXPERIMENTS ARE CARRIED OUT ON A 30 KILOWATT REFRIGERATION COMPRESSOR WITH AN EVAPORATION TEMPERATURE OF 263 K (-10 DEG C), WORKING UNDER PRACTICAL CONDITIONS IN A FLOODED SUCTION. BECAUSE OF THE LOWER SPEED DURING A GREAT PART OF TIME, THE MAINTENANCE COSTS OF THE COMPRESSOR ARE ALSO LOWER. A. L. S.
