EFFICIENCY STUDY OF OIL COOLING OF A SCREW COMPRESSOR.

Author(s) : TREE D. R., MCKELLAR M. G., FRESCO A.

Summary

IN A SCREW COMPRESSOR IT APPEARS THAT THE WAY THE COMPRESSOR IS COOLED CANHAVE AN EFFECT ON THE COMPRESSOR'S EFFICIENCY. THE PAPER PRESENTS EXPERIMENTAL DATA ON 3 DIFFERENT SCREW COMPRESSOR COOLING METHODS: LIQUID REFRIGERANT INJECTION COOLING SYSTEM ; THERMOSYPHON COOLING SYSTEM ; AND AN OIL INJECTION SYSTEM. ALL TESTS WERE CONDUCTED ON A HOT GAS BYPASS SYSTEM USING R22. THE DATA TAKEN SHOWS THAT THE OIL INJECTION SYSTEM IS SLIGHTLY BETTER THAN THE OTHER TWO. THESE TESTS SHOULD BE REPEATED WITH A HIGHER OIL FLOW RATE AND AMMONIA AS THE WORKING FLUID.
