Most central chillers run at full capacity all the time, whether you need it or not. But “Dynamic Lift” control technology dynamically adjusts capacity to meet the need, delivering substantial energy savings to a central cooling system. Here’s how it works.
Most plastics processors don’t think much about the chiller in their central cooling systems. But the monthly energy bill usually gets their attention. Question is: What can you do about it?
That out-of-sight, out-of-mind water chiller should be a primary target for energy cost reduction. Simply re-evaluating your plant’s industrial process cooling equipment can be a potential source for cost savings.
No matter how efficient your process is, there will always be some waste heat produced. Removing this waste heat from the product and process equipment quickly and efficiently is the job of a central chiller system; however, not all chillers are the same. The age of the chiller, the type of components it uses, and the control technology all contribute to the chiller system efficiency. As production levels rise and fall, the chiller system must adjust to meet the actual process load.
As the process load decreases, chillers must adjust accordingly to ensure consistent cooling temperatures for the process. That usually involves turning compressors off or using hot gas bypass to keep the compressors running and using power even when the load does not require them to run.
With the added benefit of reducing the operating cost of the chiller system, a better solution to part-load chiller system operation is to reduce the cooling capacity of the system using Dynamic Lift control technology, developed by Thermal Care.
