Energy Valve

In this video we’ll learn how an Energy valve works, how it saves energy, where it is used and how it can prevent the low Delta-T syndrome. These Energy Valves are used in the HVAC Industry for Chilled Water, Heating Hot Water and Condenser Water Heat Exchangers and Coils.
See how to avoid Low Delta-T Syndrome.

You're welcome. Thanks for watching.

Have you seen water coils used in freezing applikations?

[@MEPAcademy]

With the use of Glycol the temperature of water can be achieved lower than zero, but this is not something you would most likely see in the HVAC industry. A mixture of water and glycol is commonly used for snow melt systems, geothermal heat pumps and in typical water systems used in the HVAC industry where pipes might be exposed to freezing ambient temperatures.

Its becomming more and more a thing in the EU due to hfc and hcfc becomming more regulated and phased out.
So ammonia is often used in stead. But it has problems glycol can solve. I am doing a project for some automotive test machinery that needs to produced a test cabin temp of -20c and we are planning to use glycol and ammonia.
So was just curios if its a thing in other applications
