REPLACEMENT REFRIGERANT AND SYSTEM EVALUATION

THE CURRENT REFRIGERANTS USED IN THE VAPOR CYCLE SYSTEMS ARE SCHEDULED TO BE PHASED OUT AND REPLACED WITH REFRIGERANTS THAT ARE ENVIRONMENTALLY LESS HAZARDOUS. THESE REFRIGERANTS ARE BEING DEVELOPED TO REPLACE THOSE CURRENTLY EMPLOYED IN RESIDENTIAL AND COMMERCIAL APPLICATIONS AND WILL ALSO FIND USE IN MILITARY APPLICATIONS. IN MOST REFRIGERATION SYSTEMS SOME TYPE OF COMPRESSOR OR PUMP IS REQUIRED. THE PROPOSED EFFORT WILL INVESTIGATE THE USE OF A HIGH EFFICIENCY, LARGE DISPLACEMENT ROTARY COMPRESSOR THAT USES THESE NEW REFRIGERANTS. THIS COMPRESSOR HAS FEATURES INCORPORATED INTO ITS DESIGN THAT MINIMIZE THE AMOUNT OF INTERNAL LEAKAGE, DECREASE INTERNAL FRICTION AND MAXIMIZE THE COMPRESSOR DISPLACEMENT FOR THE WEIGHT AND VOLUME OF THE COMPRESSOR. LIMITED EXPERIMENTAL TESTS WILL BE PERFORMED ON SELECTED REFRIGERANTS FOR COMPARISON TO THEORETICAL PREDICTIONS.
