View Full Version : Dimethyl Ether as a refrigerant

Hello everyone! :)
I know that Dimethyl Ether (DME or RE170) can be used as a refrigerant. The main disadvantage of DME is its exlopsivity and the main advantages are 0 ODP and 2 or 3 GWP .Theoretically it can be used only in very small refrigeration plants. Do you actually know or heard about someone really using it?

Here is another twist on the same subject:

composed of (60%) Ammonia & (40%) Dimethyl ether (% on mass basis)


This is the only application I have heard of where dimethyl ether is used. At least in the last 50 years or so I am aware of.
