Discussion on the effect of using cold water from the dry titanium cooling outlet to further cool the liquefied circulating water
Thread Content
Hello everyone. In our factory, the quality of the circulating water is not very good. Additionally, the temperature of the circulating water is high during summer (the water supply pipes are made of fiberglass, which allows for a pressure control of only 0.22 Mpa at most; as a result, the water circulation rate is low). The cooling effect of the circulating water tank is also not optimal. My idea is to use water with a temperature of less than 15°C, obtained from the titanium coolers in the chlorine drying system, to feed into the cold water tank. From there, a pipe is installed at the outlet of the circulation pump in the cold water tank and connected to the pipes of the chiller unit, in order to cool the circulating water used in the oil cooler and the Freon cooler further. A plate heat exchanger is installed on the main circulating water pipeline, from which branches lead to the two coolers in the chiller; a bypass circuit is provided to facilitate the cleaning of the plate heat exchanger. This approach ensures that the circulating water reaches a low temperature, thereby maintaining stable operating parameters of the chiller and the overall system. I’m not sure if this approach has yielded positive results in other factories. In summer, the temperature of the circulating water in our plant can reach up to nearly 28°C, which fails to ensure the optimal operating conditions for the ice machine. I hope to get everyone’s help in providing some parameter settings. The location where cold water is supplied is 300 M away from the plate heat exchanger in the chiller plant, and the cold water circulation pump has sufficient power. 15Wt chlorine project, York chiller.
Theoretically, it is possible; it is necessary to calculate the flow rate and heat transfer amount to determine whether there is sufficient heat/cold.
Have you considered using fresh water as the cooling water for the ice machine, and then using it to replenish the water lost in the circulation system? I’m not sure how large the difference is between the amount of cooling water required by your chillers and the amount of water that needs to be added to maintain the circulation of water.
The heat transfer volume in that area where titanium is used for cooling isn’t very large; there’s no need to go to such lengths. Even if you increase the temperature of the chilled water, it will still increase the load on the chiller unit. If that’s the case, it’s better to simply add some chilled water to the circulating water. :Lol:lol In the end, it’s still necessary to calculate the heat intake as well as the capacity of the chiller units to see if it’s viable.
The design institute can come up with a plan; this requires systematic calculations
