Shouldn't we keep using the low-temperature cold water function for cleaning? The answer is yes. So, how should we clean without shutting it down?

The issue was dissected by "Cold Water Chiller in Operation Continuously Washes," a manufacturer of low-temperature coolers.

After a period of operation, machinery and equipment should be cleaned to ensure normal subsequent operation; the refrigeration system's ice-water unit should also be cleaned.

Chiller

The chemical cleaning process for the low-temperature chilled water unit, with the power not turned off, includes: Sludge Cleaning → Neutral Oil and Rust Removal Cleaning → Salt Dehydration Replacement. The purpose of the sludge removal cleaning is to utilize bactericidal action to destroy the cell structure, proteins, or enzymes of microorganisms, thereby achieving the goal of killing them. Simultaneously, by using strippers, dispersants, and other additives, microorganisms are removed from various parts of the chilled water unit and dispersed in the detergent solution, carried out of the cleaning system to create conditions for further chemical cleaning.

We have added additives, including disinfectants, strippers, surfactants, and defoamers.

Secondly, process control.

Turbidity Analysis; before cleaning, collect a water sample and retain it as a control against the water sample used in the glassification process. Take a sample every 3 hours during the stripping process to compare with the blank sample. If the turbidity values of the water sample increase, continue until the turbidity reaches 10 degrees and stabilizes, indicating that the surface slime stripping is essentially complete, and the ice-water unit has been thoroughly cleaned.
