Glycol Cooling System Design

Using the right glycol water is a better heat transfer media than glycol you can see that when you compare the specific heat of the fluids.

Glycol cooling system design.

This type of refrigerant is similar to antifreeze found in an automobile. Glycol flow control and pressure can be regulated in the system with variable frequency drives on pumps external bypass loops and with internal spring loaded relief valves. It helps maintain temperature consistency in the application. Glycol is a mixture of water and ethylene glycol.

Glycol solution in a heat exchanger during the catalyst cool down processes in hydrotreaters. Too much glycol will therefore increase energy costs as the system works harder to accomplish the desired heating or cooling. Glycol is a class of organic compounds that belong to the alcohol family. The bespoke glycol beer system.

When mixed with water and pumped through the pipes of a chilling system glycol serves to slow the rate of freezing. A central bath of glycol food safe antifreeze 70 glycol 30 water is used to cool all refrigeration equipment on your site. The glycol system works much in the same way a standard household heating system works. Since glycol has a lower specific heat than water higher concentrations of glycol in your closed loop water will reduce the heat carrying capacity of the system.

This system uses a small heat exchanger to collect heat from a type of refrigerant. For the glycol cooling system the temperature of the refrigerant is typical 5 c to 35 c lower than the glycol water temperature to allow heat to flow. Glycol must be accounted for early in the system design as using glycol with its lower heat transfer capability will impact the sizing of many of the system s components. Glycol and your chilling system explained.

Our unique design along with lancer glycol chillers can incorporate and cool all your other. Spring loaded bypass valves are installed in all g d chillers even as a redundant back up for vfd controlled pumps. At glycol cooling systems we design install and maintain bespoke energy efficient glycol beer systems that save you energy waste and money while delivering a consistent high quality draft beer ale and stout that your customers will love again and again. The bath is chilled to approximately 4 c 25 and with the use of a glycol specific high flow pump the glycol water.
