What type of glycol is used in chillers?
Glycol is a clear, odorless, slightly syrupy liquid that is used to help regulate the temperature in chillers. The most common type of glycol used in industrial chillers is propylene glycol, which is a synthetic polyol compound.
Propylene glycol is non-toxic and non-inflammable, making it an ideal choice for chillers in food processing facilities and other industries. It is also very effective in dissipating heat, and its low volatility allows it to hold its temperature for a longer period of time than other types of glycol.
A glycol chiller can help to regulate temperatures for a variety of applications, including cooling chemical tanks, cooling of wastewater, and air conditioners, as well as other liquid cooling requirements.
Why is glycol used in refrigeration?
Glycol is a type of alcohol that is frequently used in refrigeration systems because it has a lower freezing point than water, meaning it will remain in a liquid state within the refrigerator even at temperatures below water’s freezing point.
Glycol is mixed with water, typically at a ratio of 50:50, to form an antifreeze solution that is circulated through the system. The antifreeze solution is then pumped through a heat exchanger to both cool and dehumidify the air.
The glycol dissipates the heat created by the condenser, then expels it through the coils. This prevents the refrigerant from condensing inside and freezing the coils, which could damage the system. Additionally, glycol’s natural properties also provide extra protection from corrosion.
As it is hygroscopic, it absorbs traces of moisture that could otherwise damage sensitive components of the cooling system.
What’s the difference between propylene glycol and ethylene glycol?
The main difference between propylene glycol and ethylene glycol is their chemical structure. Ethylene glycol is an organic compound with two alcohol functional groups, while propylene glycol has three; this difference in structure leads to different chemical and physical properties.
Propylene glycol is a colorless, odorless, nearly tasteless, and hygroscopic liquid with a molecular weight of 76.09 g/mol. It is generally considered safer than ethylene glycol in terms of toxicity and environmental impact and is used in a variety of products, including food, pharmaceuticals, and industrial applications.
Its boiling point is 188°C (370°F) and it has a lower freezing point than ethylene glycol at minus 59°C (-74°F).
The melting point of ethylene glycol is -12°C (10°F) and its boiling point is 198°C (388°F). Its molecular weight is 62.07 g/mol and it has a strong odor and sweet taste. Due to its low freezing point, ethylene glycol is commonly used as an antifreeze for cars and other engine cooling systems.
It can also be used as a solvent in various industrial applications.
Propylene glycol is generally considered the safer of the two because it is less toxic than ethylene glycol, and biodegrades more quickly, making it a more eco-friendly choice. Additionally, it has a lower boiling point and freezing point than ethylene glycol and higher viscosity, making it a better choice for applications where it needs to remain stable at high temperatures.
Is ethylene glycol a refrigerant?
No, ethylene glycol is not a refrigerant. It is an organic compound that is most commonly used as an antifreeze in both automotive and residential applications. Ethylene glycol works to lower the freezing point of water and raises the boiling point to prevent corrosion.
It can be mixed with water in 50/50 ratios for a optimal usage for most applications. Ethylene glycol is a toxic substance and care should be taken when handling and disposing of it. Refrigerants are chemical compounds specifically designed to be used in cooling systems to transfer heat.
Common refrigerants include fluorinated hydrocarbons such as R410A or R134A, as well as ammonia and carbon dioxide. Refrigerants are usually not toxic or corrosive, but they can be hazardous to the environment if they are not properly contained.
How much glycol do you put in a chiller?
The amount of glycol to be used in a chiller depends on several factors, such as the environment, system design and the desired freeze-protection temperature. Generally, the amount of glycol used in a chiller ranges between 25% and 50%.
However, some chillers may require more glycol to provide additional freeze prevention due to the system design, or if a lower freeze protection temperature is desired. In general, you should use a concentration of glycol that’s neither too high nor too low.
Too much glycol can lead to a frozen condenser, and too little glycol may not provide enough freeze protection. When determining the amount of glycol, use manufacturer recommendations and consult the local codes for additional guidance.
