Combined optimization of air cooling and water cooling
Thread Content
Our equipment operates in a combined air-cooling and water-cooling mode. Currently, during winter, all 45 air-cooling units are operated at around 40% load; sometimes the load is a bit over 50% due to variable frequency control, while the water-cooling valve setting is less than 10%. My suggestion is to adjust the load on those 4 air-cooling units by first activating the water-cooling system and then gradually shutting down the air-cooling units. If the water-cooling system can meet the requirements, I will not use the air-cooling units at all. Is this approach the most energy-efficient and optimal? Our medium is free of water, so the issue of preventing freezing in the air-cooled tube bundles is not a concern.
Well, then it depends on what kind of water you use How much is it? It needs to be calculated
There are ideas, and that’s good. But this requires technical support. This topic can be explained with just a few simple sentences……It seems like an overly simplistic approach. Logically, all components of this system can be adjusted; even the angle of the fan blades in the cooling tower can be changed. In the case of multiple such devices, they can be adjusted as needed based on the actual usage by the production unit. If we are to determine the method that results in the lowest energy consumption, the operating procedures must include clear control measures.
When considering energy savings, we should focus solely on reducing consumption through the 45 fans
It depends on where the cold water comes from; if it comes from a cooling tower, it’s better to stop using water cooling and opt for air cooling instead.
You need to build a model for estimation, taking everything into account
