摘要

The refrigerant R723 is made up of 60 mass% ammonia and 40 mass% dimethyl ether, it isrnenvironmentally-friendly (zero ODP, insignificant GWP). R723 is used in refrigeration systems as arnworking fluid in a similar way to R717. The pressure is almost identical but R723 has a number ofrninteresting advantages over pure ammonia. With R723 the discharge temperature can be reduced byrnapproximately 20 – 25 K. The solubility for mineral oils is considerably improved and can bernextended the area of very low temperatures.
