Abstract

A solution for a "vibration-free" Joule-Thomson cooler using a sorption compressor is presented to answer the needs of potential future Earth observation IR missions with low micro-vibration levels requirements from the European Space Agency. The adopted solution includes a closed cycle JT cooler, using nitrogen as working fluid with an expected cooling power of 1.5W@80K and the fluid circulation is achieved by cycles of adsorption/desorption using metal organic framework sorbent materials. The working principle and chosen parameters of the 80 K vibration-free cooler are shown based on the various stringent requirements (temperature range, performance, consumption etc.) The characterization and validation of some components was already carried out: preliminary results are presented.
