EFFICIENCY OF REFRIGERATOR-FREEZER COMPRESSORS: OPERATING WITH R134A REFRIGERANTS.
Author(s) : RIFFE R.
Summary
RESULTS PUBLISHEDIN THE PAST OFTEN SUGGESTED THAT COMPRESSORS OPERATING WITH R134A ARE LESS EFFICIENT THAN COMPRESSORS OPERATING WITH R12. A SIMPLIFIED ANALYTICAL ANALYSIS AND EXPERIMENTS SUGGEST THAT THIS IS NOT AN INHERENT RESULT OF USING R134A BUT RATHER A RESULT OF THE OIL USED. BEARING FRICTION POWER LOSS IS HIGH IN REFRIGERATOR-FREEZER COMPRESSORS. OILS THAT ARE COMPATIBLE WITH R134A SHOW HIGHER VISCOSITY INDEXES THAN THOSE OF OILS THAT ARE COMPATIBLE WITH R12. A SIMPLIFIED ANALYTICAL STUDY PLUS TEST RESULTS SUGGEST THAT COMPRESSORS OPERATING WITH R134A WITH AN APPROPRIATE OIL NEED NOT BE LESS EFFICIENT THAN COMPRESSORS OPERATING WITH R12.
