Abstract

This work presents the analysis and design of a refrigeration cycle compressor for Methyl Linoleate (MLL) working fluid. This working fluid is being used in the active electronics payload cooling of a Venus Lander as outlined in Anderson et al. (2016) [1]. The particular selection of the FAME MLL working fluid is that FAME MLL has a critical temperature of 799 K in comparison of the Venus environment of 738 K, thus latent heat transfer can be used for heat rejection. The novelty of this present work lies in the development of a compressor which can handle the FAME MLL fluid at the high temperatures and high pressures of the Venus environment. The Cordier diagram [2] suggests the use of a reciprocating compressor design as opposed to the scroll, screw, or centrifugal compressor designs. The presentation will include SOLIDWORKS rendered mechanical design concepts of the FAME-MLL compressor rated at very high temperatures and pressures, thus fabricated from super Nickel alloys. Also, the mechanical seals used within the compressor are unique, being baselined as mechanical ring seals made from precious metals. The presentation will also present power options for the 100 W rated compressor.
