I have a chilled water system supplying one ahu for building air con that is currently been working on water only. I've been asked to make this a glycol mix so that it's temp can be lowered. the pipework is a mix of plastic and copper, the chillers are York with plate heat ex's.
My questions are;
what glycol should I use?
to what concentration should I make it?
can I use a hydrometer to measure this as I don't know how much water there is and will not be draining?
if so where can I get a hydrometer from or is there another way of measuring the concentration?
I would appretiate answers to any of those questions or just pointing in the right direction for info.
Many thanks.
