The
chiller is a kind of water cooling equipment, which can provide cooling water equipment with constant temperature, constant current and constant pressure. The cooling water is sent to the equipment to be cooled, and the chilled water takes away the heat and then returns to the water tank after the temperature rises to achieve cooling. However, in the long-term use of the chiller, there are often some dirt deposits in the chiller pipes or water tanks. How do these deposits come from?
1. Chemical processor agent
If zinc salt or phosphate corrosion inhibitor is added to the water circulation system, there will be the formation of zinc or phosphoric acid scale. Therefore, we need to regularly maintain the
chiller, which can not only ensure its cooling capacity, but also prolong the service life of the
chiller.
2. Leakage of process medium
Water cooler leaks, especially oil leaks or certain organics cause sludge to deposit.
3. Tap water
Untreated and poor replenishment water will bring sediment, microorganisms, suspended matter, etc. into the
chiller. Even if the replenishment water is well clarified, filtered, and disinfected, there will be a certain amount of turbidity and a small amount of hygienic substances. During the clarification process It is also possible to mix the hydrolyzate of the mixture, aluminum or iron ions in the replenishing water. In addition, the dissolved salts in the make-up water are carried into the circulating water system, whether pretreated or not.
4. Air
Sediment, dust, microorganisms and their spores will be brought into the circulation system with the air, and sometimes insects will also be brought into the brought system, causing blockage of the heat exchanger. When the environment around the cooling tower is polluted, corrosive gases such as hydrogen sulfide, chlorine dioxide, and ammonia will react in the unit and indirectly cause deposition.
