Performance comparison of sorption compressors for methane using metal-organic frameworks and activated carbon as adsorbents

Many optical devices can benefit from cryogenic cooling; however, the resolution of these suffers microvibration mechanical cryocoolers. Unlike cryocoolers, sorption cryocoolers do not have any active moving parts and are essentially vibration-free. Sorption thermally driven their performance is highly determined by properties adsorbents employed in compressors. In this study, thermodynamic dynamic modelling compressors adopting Saran activated carbon, MOF-5 HKUST-1 metal–organic frameworks as conducted to find suitable realize efficient compression. It found that a compressor with adsorbent has worst performance. carbon highest mass-flow rate. And whether or higher efficiency depends on operating conditions. The effects heat sink temperature heater power also investigated. analysis method be choose sorbent materials conditions when designing
