Open semi-hermetic compressors for cascade CO2 systems.

Compresseurs hermétiques accessibles pour cascade au CO2.

Summary

In comparison to conventional low temperature applications, a particularly high volumetric refrigeration capacity allows significant cost reductions in compressors and pipe-work. Even for larger capacities, this results in a potential use of compressor sizes usually found in commercial and light industrial applications. On the other hand, high operating and standstill pressures demand special criteria for compressor design and protection measures. This article is an adapted version of a paper presented at the 20th IIR International Congress of Refrigeration in Sydney in 1999, and deals with possible solutions in system layout. Protection measures and performance behaviour versus conventional plant designs, as well as lubricants are reviewed. (See also ref. 2000-1220 of the IIR Bulletin.)
