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. At this time, the water is evaporated
and the following salts (hardness materials, chloride ion, sulfate ion, etc.) are concentrated.
Namely, the condensation phenomena of such materials occur, and water quality will be
gradually degraded.
As the water and air always come in contact with each other in the cooling tower, the sulfurous
acid gas, dust, sand, etc. in the atmosphere will mix into the water, further degrading the
water quality.
In the cooling water system, problems with water are caused by these factors.
Typical problems are corrosion, scales and slimes.
(1) Water quality standard
Water quality standard is shown in table 4-2 as an example.
Table4-2 is an extract from JRA-GL 02-1994.
