Circulating water regulation
Thread Content
When adjusting the circulating water cooler, what is done for adjustment? Is it by controlling the temperature difference between the inlet and outlet water of the circulation water, by controlling the outlet temperature of the process medium, or by simply opening everything fully to uniformly adjust the inlet water temperature? Why
At present, the return water flow in our circulating water coolers is set at full capacity; the equipment itself has no room for adjustment, and the only way to control the temperature of the incoming water is by adjusting the number of fans in the circulating water station.
It depends on the situation; sometimes to lower the return water temperature, it is necessary to increase the flow rate or reduce the temperature of the medium
It depends on your actual situation; we use full opening of the return water to uniformly adjust the supply water temperature
It depends; if energy conservation is a concern, the water flow rate for each heat exchanger can be adjusted to control the temperature difference.
We regulate the water supply flow to control the outlet temperature
Keep the outlet of the circulating cooling water fully open; the temperature is controlled by the inlet pipe valve.
Reply to 1# YKQB: In fact, there are many ways to make adjustments, such as adjusting the distribution of circulating water between heat exchangers, adjusting the number of fans in operation, adjusting the opening degree of the outlet for the circulating water in the heat exchangers (with the inlet kept fully open), and adjusting the flow rate of the material, among others.
Of course, it is necessary to control the outlet temperature of the process medium; with the circulating water control valve fully open, what purpose does the control valve still serve?
Is there anything to adjust the temperature difference of the return water in the circulating water system? At what temperature difference is the heat exchange effect better?
The temperature for feeding water and recovery is generally required to be around 6 degrees. Using upper water to control the temperature is better, as it prevents equipment damage caused by rising water pressure.
