A 1-dimensional dynamic model for a sorption-compressor cell

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

“…It should be noted that the specific heat capacity at constant pressure was used to calculate the sensible heats of all the materials in some studies [13,28], whereas the type of specific heat capacity was not clearly specified in others [32,33]. For the adsorbent and adsorbed phase, c p and c v are close, whereas the sensible heat of free gas occupies a small percentage in the total input heat (less than 5% in our simulated cases).…”

“…To verify the dynamic model, the modelling results of the dynamic model are compared to the simulated and measured data of the literature [32]. In the case given in the literature, the sorption cell using Saran carbon as the adsorbent and helium gas as the working fluid was cycled between 9.2 bar and 14.5 bar.…”

“…Due to the deviation, reasonable margins should be considered using this dynamic model to design a sorption 5. (a) Predicted pressure and (b) mass-flow rate compared to the simulated and measured data of the literature [32]. The sorption cell filled with helium was initially heated with a heater power of 30 W lasting for 12 s, followed by cooling with liquid nitrogen for 78 s. The negative and positive mass-flow rates refer to the mass-flow rates of the discharge and charge phases, respectively.…”

In-flow measurement of the composition of a binary gas mixture

“…The experimental setup is based on previously designed sorption compressor cells [17]. Three of these cells are combined in parallel to generate sufficient mass flow to the flow sensors.…”

Development of a switchless sorption compressor for the cryogenic refrigeration within the METIS instrument: Part I. Theoretical design

“…In order to compare the performance and size of the METIS refrigerator with and without GGHS, a 1-dimensional dynamic model (Wu et al, 2017a) was adapted to evaluate the dynamics in the sorption compressor-cell. According to the baseline design of the METIS cooler chain (Wu et al, 2017b), the operation condition of the sorption compressors have been determined.…”
