Summary

TECHNOLOGIES IN THE DESIGN AND MANUFACTURE OF HERMETIC COMPRESSORS FOR DOMESTIC REFRIGERATORS AND AIR CONDITIONERS ARE NOW REQUIRED TO MEET TWO MAJOR MARKET FACTORS: SAVINGS IN ENERGY AND COMPACTNESS. WITH REGARD TO THE FORMER FACTOR THE AUTHORS HAVE CONCENTRATED UPON IMPROVING THE VOLUMETRIC EFFICIENCY OF MACHINES AND REDUCING FRICTIONAL LOSSES IN THE MOVING PARTS. TO ACHIEVE COMPACTNESS, THE COMPRESSORS WERE FITTED WITH MANY PLASTIC COMPONENT PARTS. WITH COMPRESSORS FOR AIR CONDITIONING, INVERTERS ARE BEING USED TO PROVIDE BETTER CAPACITY CONTROL AND THEY ALSO ENSURE GREATER MACHINE RELIABILITY, PARTICULARLY IN VIEW OF THE FACT THAT THE COMPRESSOR RUNNING SPEED IS SUBJECTED TO STEPLESS AND CONTINUOUS CHANGE FROM LOW TO HIGH SPEEDS. LUBRICATION SYSTEMS AND VALVE CONTROL HAVE ALSO BEEN IMPROVED UPON IN THE SEARCH FOR ENERGY ECONOMIES.
