  • Page 50: Water Treatment

    4-3. WATER TREATMENT The water treatment is very important to the Chiller. As the water treatment requires technical knowledge, please consult Carrier service agent. 4-3-1. Water Treatment for Chilled water and Cooling water The cooling water of an open-type recycling cooling tower lowers the temperature of the cooling water using vaporized latent heat, and is reused.
  • Page 52 [Note 1] Each item of the standard values may cause the failure due to corrosion or scale and if any item deviates from the standard value, it is assumed that corrosion or scale tends to be caused, therefore, these should be periodically managed. [Note 2] As the range of the water quality which may become usable if the water is processed differs depending on the chemicals to be used, it is not given here.
  • Page 53 4-3-2. Water treatment for long term shut down Perform the following treatment during long term shut down with no-circulation of chilled/hot water, cooling water in the Chiller. Please consult Carrier service agent for the the details. (1) Cooling water Wet lay up usually. (Keep the cooling water full in the Chiller.) In case the freezing of cooling water is likely to happen, drain it from the Chiller.
