13.2.3 Water quality
※Water quality control
When industrial water is used as chilled water, little furring may occur; however, well water or river water,
used as chilled water, may cause much sediment, such as furring, sand, and so on. Therefore, well water or
river water must be filtered and softened in softening water equipment before flowing into chilled water
system. If sand and clay settle in the evaporator, circulation of chilled water may be blocked, and thus
leading to freezing accidents; if hardness of chilled water is too high, furring may occur easily, and the
devices may be corroded. Therefore, the quality of chilled water should be analyzed before being used, such
as PH value, conductivity, concentration of chloride ion, concentration of sulfide ion, and so on.
