Apologies if this has been covered before but I couldn't find the answer I was looking for on the forums:
I have a supermarket application using direct secondary cabinets and water chillers. The total chiller capacity is 380kW. There wil be two chillers (190kW each), each with 4 compressors. The fluid is 30% prop glycol with flow and return temps of -6°/0°C.
The shop floor cabinets (around 60 in number) will each have a bypass valve arrangment when cooling is not required.
My first question is do I need a buffer vessel and secondly how do I size it if I do?
Any help would be very much appreciated.
Thanks
