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.
Glycol cooling system temperature.
A heating system with liquid volume 0 8 m 3 is freeze protected with 50 by mass mass fraction 0 5 ethylene glycol.
At standard ari 590 conditions.
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.
54 f entering fluid temperature 44 f leaving fluid temperature 95 f ambient temperature 0 0005 fouling.
This type of refrigerant is similar to antifreeze found in an automobile.
American chillers cooling tower systems inc.
The low freezing points of glycol mixtures make them ideal for cooling items below the freezing point of water.
Glycol is a mixture of water and ethylene glycol.
This system uses a small heat exchanger to collect heat from a type of refrigerant.
In geothermal heating cooling systems ethylene glycol is the fluid that transports heat through the use of a geothermal heat pump.
Glycol cooling systems uses a self contained system to cool data centers.
