Research abstract
A SAFE, NONTOXIC, NONFLAMMABLE, LOW OZONE-DEPLETING ABSORPTION REFRIGERATION SYSTEM IS BEING DEVELOPED IN THIS PROJECT. THE SYSTEM DELIVERS A RELATIVELY HIGH COEFFICIENT OF PERFORMANCE (COP) IN SMALL SCALE AIR CONDITIONING AND HEAT PUMP SYSTEMS, BUT WITHOUT THE HAZARDS ASSOCIATED WITH AMMONIA. REFRIGERANTS HAVE BEEN IDENTIFIED THAT CAN BE USED DIRECTLY IN INHABITED SPACE AND ALSO HAVE THE POTENTIALFOR HIGHER COPS THAN CURRENTLY KNOWN ABSORPTION PAIRS. PHASE I OF THIS RESEARCH INCLUDES MEASURING THE PROPERTIES FOR ONE SELECTED REFRIGERANT/ABSORBENT PAIR. THE EXPERIMENTAL DATA WILL BE USED TO CARRY OUT CYCLE ANALYSES TO EVALUATE THE PERFORMANCE IMPROVEMENT IN THE NEW SYSTEM. IN PHASE II, ADDITIONAL REFRIGERANTS AND ABSORBENTS ARE TO BE INVESTIGATED TO OPTIMIZE THE ABSORPTION CYCLE, AND A THREE-TON PROTOTYPE UNIT IS TO BE BUILT TO DEMONSTRATE THE IMPROVED PERFORMANCE.
