Ammonia-dimethylether (R723) as a new refrigerant blend.

Author(s) : KRAUSS D., SCHENK J.

Summary

R723 is made of 60 mass% ammonia and 40 mass% dimethylether and it is environmentally-friendly (zero ODP, insignificant GWP). R723 is used in refrigeration systems as a working fluid in a similar way as R717. The pressure is almost identical but R723 has a number of interesting advantages over pure ammonia. With R723, the discharge temperature can be reduced by approximately 20-25 K. The solubility for mineral oils is considerably improved and can be extended to the area of very low temperatures.
