At the planning stage, designers of refrigeration plants which serve mine cooling systems are often faced with the questions: how many chillers do I require for a certain duty? How can I optimally configure them for peak load and/or seasonal efficiency? For such ostensibly simple questions the answers, unfortunately, are not as straightforward. It turns out, a myriad of configurations exist, each with their merits and shortcomings and therefore every design should be fit for purpose. For the sake of this article we show the three most simplistic configurations in the accompanying diagram.
