ADX Ammonia System Evacuation


When water is present in a DX ammonia system, it changes the characteristics of the refrigerant and the operation of the system. Because a DX evaporator coil boils off 100% of the refrigerant prior to the end of the circuit, a small amount of water in the system will create a high water content at the coil exit. This will adversely affect the superheat and refrigerant feed.  Recirculated ammonia systems do not utilize 100% evaporation, so any water accumulates on the low side, unnoticed, until the plant efficiency degrades from lower required suction pressures.  Please refer to the Colmac DX Ammonia Piping Handbook for a more thorough explanation.
