Utilisation d'un mélange ammoniac/diméthyléther (Schick R-723) dans les systèmes frigorifiques de taille moyenne.

Use of ammonia/dimethylether (Schick R-723) blend in medium refrigeration plants.

Auteurs : KRAUSS D.

Résumé

This refrigerant is made up of 60 mass% ammonia and 40 mass% dimethylether, is environmentally-friendly (zero ODP, insignificant GWP), and available in adequate quantities in returnable steel tanks and containers. It is used in small and medium refrigeration systems as a working fluid in a similar way as R-717. The pressure is almost identical but this blend has a number of interesting advantages over pure ammonia. With this refrigerant, the discharge temperature can be reduced by approximately 15-25 degrees. The solubility for mineral oils is considerably improved and can be extended to the area of very low temperatures. Continuing the poster presentation of the previous conference, the author demonstrates now the applicability of this refrigerant in real refrigeration plants and under various ambient conditions.
