“…This rise was accompanied with an increase in the average global temperature [1][2][3], resulting in a dramatic increase in the demand for cooling. This demand was largely supplied by systems utilizing chlorofluorocarbon (CFCs) and hydrochlorofluorocarbon (HCFCs) refrigerants before their phaseout [4,5]. Also, these systems were driven by electricity generated using fossil fuels.…”

The adsorption capacity of adsorbent materials at low relative pressure range is a crucial parameter that guarantee the high overall performance and efficiency of adsorption cooling and water desalination systems. MIL-101(Cr) is a metal-organic framework (MOF) material with a high-water vapour uptake of 1.36-1.47 g 2 H O g ads-1. However, MIL-101(Cr) exhibits an IV isotherm (S-shaped isotherm) which means that the high-water uptake only takes place at high relative pressure (≥ 0.5). This drawback makes MIL-101(Cr) impractical for adsorption applications working at lower relative pressure such as adsorption cooling and desalination with cooling effect which operate at relative pressures ≤0.4. In this work, MIL-101(Cr)/CaCl 2 composites were synthesized, the unsupported and CaCl 2 supported materials were fully characterized in terms of their structure (XRD), thermal stability, vibrational spectroscopy structure, morphology (SEM), water adsorption capacity and BET surface area. As a result, incorporating CaCl 2 into the MIL-101(Cr) structure significantly enhanced water adsorption characteristics in the desired relative pressure range as the water vapour uptake for Comp_1:8 CaCl 2 composite increasing from only 0.1 g 2 H O g ads-1 for as-synthesized MIL-101(Cr) to 0.65 g 2 H O g ads-1 at a relative pressure of 0.3.

“…Choi [5] had introduced the term "nanofluids", a reference to suspended nanoparticles smaller than 100 nm and dispersed into base fluids. The common base fluids used were typically water (W), ethylene glycol (EG), W/EG base mixture and oil shown by Redhwanet al [6]. Earlier studies by Lee et al [7] and Xuan and Li [8] proved that nanofluids have higher thermal conductivity compared to their base fluids.…”

The heat exchanger performance of a system can be enhancedemploying a combination of passive strategies, particularly nanofluids and varied structures of fins geometries. These methods can enhance the heat transfer coefficient and consequently reduce the weight of the system. In this paper, the effect of fin geometry and nanofluids in Plate Fin Heat Exchangers (PFHE) are studied by numerical analysis. The forced convective heat transfer performance is evaluated in terms of Nanofluid Thermal Performance Number (), Nusselt number and Colburn j factor.Pressure drop characteristics is estimated in terms of Fanning friction factor 'f' of the CNT-H2O nanofluid in the turbulent zone of Reynolds number in the range 3000 to 7500. Thermo-hydraulic performance variations with rectangular fin geometry and volume fraction 3% to 5% of the nanoparticles in nanofluid is analyzed.Performance of the nanofluids are also compared with the performance of pure water. It has been observed that heat transfer enhancement using nanofluid is more than 20%. A correlation of Fanning friction factor 'f' and Colburn j factor with geometry of fin, Reynolds number and volume fraction of nanofluid is developed. This correlation is the heart of the rating and design of PFHEs.
