Gravity Independent Compressor, Phase I

Completed Technology Project

Project Description

Gravity Independent Compressor, Phase I
We propose to develop and demonstrate a small, gravity independent, vapor compression refrigeration system using a linear motor compressor which effectively addresses the efficiency, lubrication, scalability, and/or longevity issues limiting current space flight refrigeration systems. Unlike previous and currently used thermoelectric, Stirling, oil-free reciprocating and diaphragm compressor systems, the linear compressor will provide very high efficiency, excellent capacity modulation, nearly unlimited scalability, and very long life all due to the hydrostatic bearing of the linear compressor and use of the reverse-Rankine cycle. The linear can also readily be developed as a single unit two-stage compressor for higher lift applications. More »
