Remplacement du R12 par de l'éther diméthyle.

Dimethyl ether as an R12 replacement.

Auteurs : ADAMSON B. E. B.

Résumé

Drop-in replacements for R12 which can be used in large flooded refrigeration systems, without extensive system modification or cleanout are uncommon. Zeotropic blends are unsuitable, due to fractionation of components. The paper proposes dimethyl ether as a single-component, drop-in replacement for R12 in flooded systems. Its saturation pressure/temperature relationship is very close to R12, heat transfer properties are significantly better and energy costs are slightly lower. Compressor capacity is close to R12 capacity at medium temperatures, but slightly lower. Compressor capacity is close to R12 capacity at medium temperatures, but slightly lower than R12 capacity at low temperature. It is non-toxic in normal usage, low cost, widely available and environmentally safe, although flammable.
