Let’s discuss how to properly control the temperature difference between the inlet and outlet water of a water cooler
Thread Content
For energy-saving reasons, our plant requires that the temperature difference between the inlet and outlet water of all water coolers be kept above 6 degrees. However, due to process requirements and design constraints, it is difficult for some water coolers to meet this standard; as a result, some liquid yield is lost and the flow rate of the circulating water is too low. Recently, there have been several instances of leaks inside the water coolers. Please share your opinions on how to achieve an appropriate level of control.
Given a certain requirement for cooling capacity, controlling the temperature difference of the cold water necessitates an increase in the circulation volume. If the heat exchange area is sufficient, then increasing the pump pressure is an option; however, this leads to higher power consumption – so how can energy savings be achieved? If the pressure rises above the design pressure of the heat exchanger, leakage will certainly occur.
I came across this topic while working on a paper today. I have been working in a refinery for nearly 20 years, and I have encountered many problems related to water coolers in actual production; I have both successful and unsuccessful experiences in this area. I have conducted extensive research on circulating water and water coolers, as well as on the use of water coolers in other companies. I found that many technicians and workshop supervisors have various misconceptions: 1. Should the temperature difference of the circulating water in water coolers be controlled? 2. How to control it? Is it export control or import control? 3. What temperature is appropriate? 4. Is internal leakage in the circulating water cooler directly related to controlling the temperature difference of the circulating water? 5. What is the typical operating cycle for a circulating water cooler? What factors are directly related to it? Due to time constraints today, I can’t discuss these issues in detail with you all, but if you take the time to study them carefully, you’ll be able to find the answers on your own. Sometimes, mistakes that persist for years end up being considered correct, and they are even included in the operating procedures. It’s truly sad for those of us who work in production technology. I will come back again.
The problem seems simple, but it actually involves many issues in practical work. I’m looking forward to your guidance on the third floor
You on the third floor can’t just ask questions without providing answers. I’m a newcomer in the refinery, and currently there are quite a few problems with the circulating water heat exchangers in our plant. Please share your experience quickly, so that those of us who are newer to this field can avoid making unnecessary mistakes! Looking forward to it!
I’d really like to hear the analysis from the third floor.
Just consult the water supply technicians at your company and you’ll know.
