Numerical and experimental evaluation of advanced metal-organic framework materials for adsorption heat pumps

[摘要] In this study the potential of a number of metal-organic framework materials namely; MIL-101(Cr), MIL-100(Fe), CP0-27(Ni) and aluminium fumarate was investigated in various adsorption applications such as heat pump, water desalination and heat storage. The properties of MIL-101(Cr) in terms of thermal conductivity and water vapour capacity were further improved through synthesizing novel composites with graphene oxide (GrO) and calcium chloride (CaCl\(_2\)). Also, the adsorption isotherm shape and capacity of MIL-100(Fe) were tuned through synthesizing two core-shell mechanism composites. The core-shell composites of MIL-101(Cr)/MIL-101(Fe) and CP0-27(Ni)/MIL 100(Fe) were synthesized to use the advantage of the high-water vapour uptake of MIL-101(Cr) in the high relative pressure and of CP0-27(Ni) in the low relative pressure range. Also, integrating the MOF material as a coated layer instead of the granular form was investigated as an alternative for conventional packed adsorption beds. MIL-100(Fe) and aluminium fumarate were chosen to be experimentally tested in a two-bed adsorption system. The effect of various operating conditions such as chilled water inlet temperature, cycle time, adsorption bed cooling water inlet temperature, desorption bed heating water inlet temperature and condenser cooling water inlet temperature was investigated.
