“…The proposed system employing ethanol and activated carbon pair had the maximum COP of 0.68 at a generator temperature of 95 °C. Apart from modified cycles, reactor geometry also plays a crucial role in system performance that has been extensively discussed in the existing literature. , Still, however, for CO 2 -based ADCS, it is very limited. , …”

The current investigation explores the CO 2 adsorption capacity of an indigenous coconut-shell-derived activated carbon, namely AC CARB 6X12 55, at an adsorption temperature and pressure of 5−70 °C and 0−42 bar, respectively, suitable for CO 2 -based adsorption cooling applications using an in-house developed high-pressure test facility. Additionally, experiments are conducted to measure thermal diffusivity, thermal conductivity, and specific heat of activated carbon using the hot-disk method on a TPS 2500 S analyzer. The activated carbon possesses the maximum CO 2 adsorption capacity of 0.70 kg/kg at 5 °C and 32 bar. Isotherm modeling is carried out based on experimental data employing Toth, D−A, and modified D−A isotherm models, followed by detailed thermodynamic investigation to estimate the heat of adsorption, adsorbed phase-specific heat, enthalpy, and entropy. Based on the adsorption isotherm data and thermophysical properties, study is extended to explore the performance of different advanced CO 2 -based adsorption cooling systems employing internal heat and mass recovery schemes, an ejector expansion, and a thermoelectric subcooler. The results confirm that the suggested cycle modifications are crucial for cooling applications, as a maximum COP and SCE of 0.341 and 44.88 kJ/kg, respectively, with an increment of 163% in system COP compared to the basic cycle, are achieved.

“…For these reasons, it is critical to assess the use of refrigerants and advanced technologies to promote sustainable and more efficient energy use. Numerous studies approach this challenge by optimizing a process flowsheet, resulting in significant engineering improvements to advance efficient energy transfer for sorption cooling. − However, limited comprehensive and systematic evaluations have been performed to address this challenge from a chemistry perspective. In this context, this review focuses on summarizing the existing literature around engineered control over the chemistry/structure of sorbents to optimize their interactions with diverse fluid media, advancing sorption-based cooling technology.…”

The energy demand for traditional vapor-compressed technology for space cooling continues to soar year after year due to global warming and the increasing human population's need to improve living and working conditions. Thus, there is a growing demand for eco-friendly technologies that use sustainable or waste energy resources. This review discusses the properties of various refrigerants used for adsorption cooling applications followed by a brief discussion on the thermodynamic cycle. Next, sorbents traditionally used for cooling are reviewed to emphasize the need for advanced capture materials with superior properties to improve refrigerant sorption. The remainder of the review focus on studies using engineered nanoporous frameworks (ENFs) with various refrigerants for adsorption cooling applications. The effects of the various factors that play a role in ENF−refrigerant pair selection, including pore structure/ dimension/shape, morphology, open-metal sites, pore chemistry and possible presence of defects, are reviewed. Next, in-depth insights into the sorbent−refrigerant interaction, and pore filling mechanism gained through a combination of characterization techniques and computational modeling are discussed. Finally, we outline the challenges and opportunities related to using ENFs for adsorption cooling applications and provide our views on the future of this technology.
