Ammonia as a refrigerant of choice
This paper reports that the greatest potential for a swing to the use of ammonia would be in the following areas: Large, central facility-type air- conditioning applications. Central district heating and cooling systems, with isolated engine room facilities, represent a natural for the advantages of ammonia screw compressor water or glycol chilling over the R-11 replacement systems. Latent heat storage systems. Here, the long history of ammonia systems (primarily in the dairy industry) will bring ammonia back into the picture. This applies to both ice-builder and ice accumulator systems. A large system of this type is being built for an industrial air-conditioning application in the Midwest and should be available shortly for case history write-ups. Packaged water chilling systems in the 30-200 ton capacity range. At least two manufacturers or assemblers are considering offering standard units in this area. The advent and widely increasing use of screw compressors has added to the potential for ammonia applications. (Ammonia was the predominant refrigerant for the first screw compressors.) Use of screw compressors instead of centrifugals is predicted to increase.
