Glycol is a freeze protection added to water when using chilled water or condenser water systems (like automotive anti-freeze). It is used in most applications where water lines are affected by cold ambient conditions. The terms are used interchangeably in some cases, as many sites run chilled glycol through their chillers instead of straight water because the water lines are outside. The big difference is the heat transfer properties of glycol are not as good as straight water, so the equipment is de-rated depending on the glycol/water mixture.
