Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics.Apr 18, 2016
What is glycol used for in refrigeration?
Glycol chillers are a specific kind of refrigeration system, often used to cool a variety of liquids, including alcohol and other beverages. Using a chiller allows producers to lower the temperature of the product dramatically over a short period of time, depending on the production needs.
Are there different types of glycol?
There are two main types of glycol used for this function: ethylene and propylene.Sep 28, 2020
How is glycol used in chilled water systems?
Percentage Glycol in Chilled Water Systems For many chiller types, ethylene glycol is mixed with water at a ratio of 60/40. This higher percentage of glycol boosts the mixture's antifreeze properties significantly. This is useful in cases where rapid cooling is required.Dec 3, 2019
What is the purpose of glycol in a water cooled system?
Glycol is a water-miscible coolant that is frequently used in heat transfer and cooling applications. It provides better heat transfer parameters than water, and can be mixed with water to provide a variety of heat transfer characteristics. Glycol comes in two varieties: ethylene glycol and propylene glycol.Apr 18, 2016
Which glycol is used in chiller?
For many chiller types, ethylene glycol is mixed with water at a ratio of 60/40. This higher percentage of glycol boosts the mixture's antifreeze properties significantly. This is useful in cases where rapid cooling is required.Dec 3, 2019
Can glycol be used as a refrigerant?
From the above analysis, it's clear that glycol has refrigerant properties that are more suited for use in chillers expected to function in low-temperature environments. In these thermal conditions, a water coolant will freeze and obstruct chiller circulation while diminishing overall efficiency.Dec 3, 2019
What's the difference between propylene glycol and ethylene glycol?
There are two main types of glycols: ethylene glycol and propylene glycol. The number one difference between the two glycols is that ethylene glycol is toxic and propylene glycol is not, allowing propylene glycol to be purchased as food grade in addition to the technical or industrial grade.Jan 15, 2021
How much glycol do you put in a chilled water system?
Never use less than 25% Glycol, this will ensure that an adequate quantity of inhibitors are present. Never over-mix – use only the glycol concentration necessary to protect the equipment.Sep 8, 2016
How glycol is used in chiller?
A chiller is a type of refrigeration system that cools a tub of glycol to reduce its temperature. The glycol is then pushed through a closed circuit of tubing or piping that is connected to the glycol chiller. This circulates cooled glycol and helps to reduce the temperature of whatever is attached to the system.Nov 16, 2020
Can you use glycol in a water chiller?
The use of an industrial inhibited glycol and water mixture is recommended in most water chiller systems. Ethylene and Propylene are the two standard types of inhibited glycols commonly used. The main job of glycol is to prevent freezing of the process fluid and ensure consistent flow at the operating temperature.
