Advanced screw refrigerant dry screw compressor
Annotation
Extensive research at the Department of refrigerating machines and NPE of ITMO University of screw refrigerant dry screw compressor showed undeniable advantages of use such compressors in vapor refrigerating machines . However, present dry screw compressors are called "dry" just nominally. The compression area oil penetration protection measures that used in such compressors does not provide long-term maintaining the maximum low oil concentration in the operating fluid. Therefore it is necessary to improve the design of Screw Compressors by excluding or change the units require lubrication. In this paper proposes a screw compressors construction that fully eliminates oil from machin .
