REFRIGERATION EQUIPMENT FOR FISHERY VESSELS USING SCREW COMPRESSORS.

Author(s) : BYKOV A. V.

Summary

NEW SERIES OF THE UNIFIED MARINE REFRIGERATING MACHINES AND UNITS WORKED OUT ON THE BASIS OF THE VERTICAL SEMI-HERMETIC SCREW COMPRESSORS OPERATE ON R22 IN THE RANGE OF THE OPERATING BOILING TEMPERATURES FROM 233 TO 283 K (-40 TO 10 DEG C). THE UNITS OPERATE IN THE CYCLE WITH THE REFRIGERANT DOUBLE THROTTLING AT THE BOILING TEMPERATURES FROM 253 K (-20 DEG C) AND BELOW. THE EQUIPMENT CONTROL SYSTEM IS DESIGNED ON THE BASIS OF THE MICROPROCESSOR TECHNOLOGY. THE COMPRESSOR HAS A SPECIAL SYSTEM OF OIL SEPARATION. THE VERTICAL COMPRESSOR CONSTRUCTION GIVES THE SIGNIFICANTIMPROVEMENT OF THE ACOUSTICAL PROPERTIES, PROVIDES STABILITY AT HEELS AND TRIMS, HIGH RELIABILITY AND SERVICEABILITY. THE PAPER GIVES THE COMPARABLE ANALYSIS OF THE TECHNICAL ECONOMIC PARAMETERS OF MACHINES AND UNITS USING THE CYCLE WITHTHE TWO-STAGE COMPRESSION AND SINGLE STAGE COMPRESSION WITH THE DOUBLE THROTTLING.
