AMMONIA AS A REFRIGERANT IN LIGHT OF THE CFC PHASE-OUT.

Author(s) : COLE R. A.

Type of article: Article

Summary

THE AUTHOR ARGUES THAT ITS THERMODYNAMIC AND PHYSICAL PROPERTIES MAKE AMMONIA AN OUTSTANDINGLY EFFICIENT AND CHEAP REFRIGERANT WHICH HAS NO OZONE DEPLETION PROPERTIES AND IS NOT A GREENHOUSE GAS. MANY PAST OPERATIONAL DIFFICULTIES HAVE BEEN OVERCOME BY THE USE OF SCREW COMPRESSORS WHERE OIL COOLING ENABLES HIGH COMPRESSION RATIOS TO BE USED WITHOUT EXCESSIVE DISCHARGE TEMPERATURES. THIS MAKES AIR-COOLED CONDENSERS A POSSIBILITY. THE PRODUCTION OF QUITE SMALL SCREW COMPRESSORS WILL ENABLE UNITARY SYSTEMS TO BE DESIGNED. OTHER ADVANTAGES COME WITH CHEAPER, SMALLER PIPEWORK, THE LACK OF OIL MISCIBILITY, AND GREATER HEAT TRANSFER COEFFICIENTS. D.W.H.
