Glycol/water refrigerant properties
Glycol/water refrigerant properties
(OP)
I am looking at modifying a heating cooling loop on an old section of process plant. The plant uses a 50:50 by weight mix of ethylene glycol and water as a heat transfer fluid. We dont have any data on the transport or thermodynamic properies of this mix as most our new units are running on syltherm. Does anyone know a web site where I could get properties like the density and viscosity of this mixture for the temperature range -20C to +95C?





RE: Glycol/water refrigerant properties
I did this search some months back in Google and came up with what seemed an endless litany of information. I concentrated on Propylene Glycol, my favorite because of the FDA approval, instead of Ethylene Glycol but the latter is also included in the information found in the following:

This should save you about an hour in finding the useful sources. I hope it helps you out.
