Performance, leak behaviour, flammability and oil-return properties of a new R22 substitute.

Leistungbestimmung, Leckagenverhalten, Brennbarkeit und Ölrückfüshrungseigenschaften eines neuen R22 Ersatzstoffes.

Author(s) : ROBERTS N. A.

Summary

The paper discusses a new blend of R125, R134a and butane that possesses a performance comparable to R22 and a smaller temperature glide than R407C. Called ISCEON 59, the blend can be used with mineral oils or akylbenzol oils. Independent calorimeter tests were done. Details are given on a conversion, the flammability of the blend, a worst-case leak, and the oil-return behaviour compared to R22.
