Regarding the issue of how to control the temperature of the fluid in the water cooler
Thread Content
Here, our water coolers use the outlet temperature of the circulating water to control the medium temperature. A friend of mine who works in a power plant said that their oil coolers use the inlet temperature to control the oil temperature. Which method is better?
The entrance is better; exit control feels like holding in urine
The export control response time is long, and the flow rate does not change significantly! Entry control is timely with a fast response time, but due to control at the source, flow rate fluctuations are significant, which hinders stable control.
