| Automatic Tube-cleaning of Seawater-cooled Condenser
In a water-cooled air conditioning system, heat is rejected from the refrigerant to the cooling water in the condenser. The impurities in the cooling water circuit are accumulated, and thus the scales and deposits are built up in the condenser tubes, creating fouling problems on the condenser heat transfer surfaces. When fouling and scaling in the condenser increase, the efficiency of the condenser will deteriorate and thus increase chiller energy consumption.
The automatic tube cleaning system is usually installed as an integral part of the condenser. The system cleans the condenser tubes by circulating a number of soft sponge balls through the tubes at pre-set time interval. Since the balls are soft and light in nature, they will not cause any damage to the condenser tube surface and can be carried easily through the tubes by the flowing of water.
