Glycol Cooling System Temperature

Glycol is a mixture of water and ethylene glycol.

Glycol cooling system temperature. Example expansion volume in a heating system with ethylene glycol. Using a chiller allows producers to lower the temperature of the product dramatically over a short period of time depending on the production needs. This system uses a small heat exchanger to collect heat from a type of refrigerant. Recommends propylene based glycols because of their non hazardous nature and as such we must be aware of the effects on the standard refrigeration heat exchangers and pumps.

This type of refrigerant is similar to antifreeze found in an automobile. A heating system with liquid volume 0 8 m 3 is freeze protected with 50 by mass mass fraction 0 5 ethylene glycol. The low freezing points of glycol mixtures make them ideal for cooling items below the freezing point of water. Glycol chillers are a specific kind of refrigeration system often used to cool a variety of liquids including alcohol and other beverages.

Cooling in brewing and other applications. The installation temperature of the system is down to 0 o c and the maximum medium operation temperature is 80 o c. Mixtures of propylene glycol with water follow a similar pattern with a 60 40 mixture of propylene glycol with water having a freezing point of 48 c 55 f. In geothermal heating cooling systems ethylene glycol is the fluid that transports heat through the use of a geothermal heat pump.

Ethylene glycol is also commonly used in chilled water air conditioning systems that either place the chiller or air handlers outside or must cool below the freezing temperature of water. American chillers cooling tower systems inc.
