It’s most familiar to people as an ingredient in antifreeze for automotive engines and mechanical cooling systems. Glycol has the ability to absorb and release large amounts of heat without changing its temperature. This makes it ideal for use in refrigeration ...
WebAug 28, 2024 · In Equation 2.2.1 the freezing point depression of a non-ionic solution is described. Where ∆T f is the change in the initial and final temperature of the pure solvent, K f is the freezing point depression constant for the pure solvent, and m (moles solute/kg solvent) is the molality of the solution. ΔTf = Kfm. WebDOWFROST™ 35% inhibited propylene glycol (PG) is a prediluted, ready-to-use thermal …
WebWater expands as it freezes and this can cause permanent damage to the evaporator. Adding glycol to your coolant reduces the freezing point of the coolant to around -34°C, preventing any risk of damage to your chiller caused by freezing. Glycol does not transfer heat as well as pure water (Fig. 2 & 3). It is therefore preferable to use 100% ...
