Discussion on utility system issues
Thread Content
The utility gas phase materials are supplied; a stable pressure is sufficient, which can meet the requirements of various processing steps effectively； It’s just that liquid-phase materials are difficult to handle. For example, in the chilled brine system, when only 30% of the processing units are in operation, running two circulation pumps in my cooling system often results in overcurrent, as well as significant vibration of the pumps. On the other hand, using three pumps does not seem to be energy-efficient. This means that in my liquid-phase system, even if only one processing unit is in use, only one pump needs to be operated; however, for the entire circulation system to function properly, all the circulation pumps must be used. This issue is quite troublesome; the circulation pump needs to be repaired frequently. Please discuss it together.
Haha, there are two approaches. First, for the process units that are not in operation, it is required that they close the inlet and outlet valves for the circulating water at the same time. It doesn’t matter whether they close the valves of individual heat exchangers or the main valves for those processes, as long as it does not affect other operating process units. Second, with the approval of management, the supply of circulating water to those processes that are not in operation can be stopped, which is how true energy savings and reduced consumption can be achieved.
