Chiller is a kind of water cooling equipment, which can provide constant temperature, constant current, constant pressure cooling water equipment. Its working principle is to first inject a certain amount of water into the water tank inside the machine, cool the water through the refrigeration unit system, and then the water pump The low-temperature cooling water is sent to the equipment to be cooled. The chilled water takes the heat away and the temperature rises and then returns to the water tank to achieve the cooling effect. However, in the long-term use of the chiller
, there are often some dirt deposits in the industrial chiller
pipes or water tanks. How did these deposits come? 1. Tap water
Untreated bad makeup water will bring sediment, microorganisms, suspended matter, etc. into the chiller. Even if the makeup water is clarified, filtered, and disinfected well, there will be a certain amount of turbidity and a small amount of sanitary matter. The clarification process It is also possible to mix the hydrolysis products of the mixture, aluminum or iron ions in the make-up water. In addition, the dissolved salts in the make-up water will be brought into the circulating water system whether or not they are pretreated. 2.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 system, causing blockage of the heat exchanger. When the surrounding environment of the cooling tower is polluted, corrosive gases such as hydrogen sulfide, chlorine dioxide, ammonia will react in the unit and cause indirect deposition. 3.Chemical treatment agent
If zinc salts or phosphate inhibitors are added to the water circulation system, zinc deposits or phosphate scales are formed. Therefore, we must often perform maintenance work on the ice chiller, not only to ensure its refrigeration capacity, but also to extend the life of the chiller. 4. Leakage of process media
Water cooler leaks, especially oil spills or some organics that cause sedimentation.
