Summary:Even small amounts of water in an ammonia refrigeration system can increase energy costs substantially. (Imagine about a cup of anhydrous ammonia mixed with a gallon of water.) It might be intuitive to think that the ammonia needed to run in a refrigeration system would have to be purer than household ammonia, but how pure is pure enough? Even a small amount of water contamination in an ammonia refrigeration system can cause substantial corrosion on metal filters, compressor crankshafts, compressor shaft seals and other metal components. Throughout the life of an ammonia refrigeration system, water enters at various times and places as a result of the system's construction, operation and servicing, as well as through humidity in the air.
