How to Clean a Chiller?

As a fixed asset of an enterprise, the chiller is an essential product for enterprise personnel to maintain and maximize its utility. Since the long - term operation of the chiller can cause a thick layer of scale to form on the surface of the condenser, which interferes with the normal operation of the chiller. For example, it can lead to low work efficiency or easy damage. Therefore, it is absolutely necessary to carry out necessary cleaning of the chiller.

How to clean the chiller? We should distinguish between water - cooled and air - cooled chillers. Water - cooled chillers are mainly used to remove the scale on the chiller. The cleaning period depends on the water quality. For poor - quality water, it should be cleaned at least once every 12 months; if the water quality is good, it can be cleaned once every 2 years on average. Air - cooled chillers use air as the cooling medium. Since there is often dust in the air, some dust will stick to the outer surface of the condenser fins. After a period of time, the cooling effect of the chiller condenser will gradually deteriorate. In harsh local environments, it is prone to aging. Therefore, the chiller should be regularly maintained and cleaned.

The cleaning method of the air - cooled chiller is as follows: As there is a lot of dirt during the maintenance and cleaning of the chiller, a non - corrosive cleaning agent should be used to clean the heat - dissipation pipes and fins to improve the heat - dissipation effect. Now let's briefly talk about the main steps of cleaning the chiller. First, disassemble the parts. If you want to clean the chiller, it must be disassembled first, because the parts to be cleaned are inside the machine body and not easy to see. The various parts of the chiller are intertwined, the circuit is complex, and disassembly is difficult. This is to understand the overall structure of the chiller. Second, connect the cleaning equipment to the condenser. After the disassembly in the previous step, find the water inlet direction of the condenser, connect it to the water inlet or outlet of the water pump, and then heat the pipes with tools. Third, add chemicals for cleaning.

After each step is completed and the pipeline is connected, rinse it with clean water about 20 times, then drain the sewage and repeat 3 times. After the cleaning is completed, the most important step of adding chemicals for cleaning is also completed. Of course, its pH value must be maintained between 4 - 5 and remain for 2 - 3 hours. Finally, eliminate the chemicals, then wash away the remaining chemicals so that the pH value is maintained at 6.5. Fourth, reassemble it to its original state.

After cleaning, the installation is completed. These are the main steps of cleaning the chiller. Is it easy? But I think it's better to ask professionals to clean it. After all, disassembling the machine can easily cause damage to the parts. If the chiller breaks down while cleaning the machine, it really isn't worth the loss.
