Mind Your Refrigeration Systems, Part II

摘要

IN PART I of this two-part series, we talked about fluid management (http://goo.gl/yHXAeE). Now, let's discuss some minimal or low-cost measures in refrigeration and chiller systems that can provide some "quick wins" for better energy efficiency. Refrigeration-and-chiller-system performance and energy efficiency are not key performance indicators in most plants that I have worked. Because these systems are part of the plant's utilities infrastructure, they typically get the least amount of attention due to other pressing issues at a plant. Hence, they continue to function year after year and the single key parameter monitored is the refrigeration temperature the process requires.
