Hi - I am a newbie to this forum and seek the help of much wiser members (that I think includes everybody). I run a maintenance department and our factory has a number of small internal process chillers of various sizes. I am installing a couple of external chillers of 50kW each with the intention of getting rid of the internal ones. I have been advised to use a buffer/weir tank and due to limited space have opted for a 1000 litre unit. My question is about the connections to the weir tank - basically where to take the water out and where to return it too. Also the best point for connection of the two chillers, flow and return. I could really do with a simple schematic also showing the weir and principal of operation including thermal flow. Any help is greatly appreciated.
