This paper deals about the effects of water contamination in an industrial ammonia refrigeration system. Water contamination can lower system efficiency, and increase the electrical costs required to run the system’s refrigeration compressors.
For a given pressure, the addition of water to the ammonia will raise its temperature. At typical suction pressures, the addition of 10% water by weight will increase the evaporator temperature by about 4°F (2°C).
