What is a COC in a cooling system?

The COC specifies, how often a fresh water added into the loop, can be used or pumped around, before the water has to blown down or bleed off from the cooling tower. In detail this means, in a open cooling water system there are usually cooling towers and consumers, such as heat exchangers or similar. The cooling water is circulated all the time.

What does COC stand for in a cooling tower?

The ratio of dissolved solids in the circulating water to the make-up water is known as the cycles of concentration (COC) (Dhoble, Ahmed, & Agarwal, 2017). In most cases, cooling towers are designed to achieve of COC 6 or above. ... ...

What are cycles of concentration (COC) in a cooling tower?

Even with the best chemical treatment program, impurities in the cooling tower can only be allowed to accumulate to a certain level before the scaling potential overwhelms the chemical treatment. The amount to which the impurities are allowed to concentrate over those in the cooling system makeup water is known as the cycles of concentration (COC).

How do you measure COC in a recirculating cooling tower?

To measure COC in a recirculating cooling tower, measure the conductivity of the incoming makeup water and the recirculating cooling tower water. The recirculating water conductivity will be the same as the blowdown water. Conductivity is commonly used to estimate COC.

What is the relationship between COC and water evaporation loss?

The cycle of concentration (COC) can be adjusted to allow for lower rates of water use, corresponding to lower rates of water chemical treatment use. To determine the blowdown rate needed to operate at a given COC, use the relationship between water evaporation loss and COC.

Is COC a promising candidate for energy storage?

It is worth noting that so high η at high electric fields has rarely been observed in present linear polymer dielectrics, confirming COC would be a promising candidate for energy storage. To evaluate the performance of COC films at high temperature, we measure Ue and η of COC films at 80 °C, 120 °C, and 140 °C, which is shown in Fig. 5 b–d.
