Résumé

A vapor compression heat pumps (VCHPs) can achieve a high coefficient of performance (COP), but the lack of eco-friendly fluorocarbon refrigerants is a serious problem. On the contrary, an adsorption heat pump (AHP) is a heat-driven heat pump that does not use fluorocarbon refrigerants but is less compact and has higher installation costs. To overcome the limitations of VCHP and AHP, this study proposes a hybrid compression–adsorption heat pump (HCA-HP) cycle that circulates a mixture of CO2 and a porous metal–organic framework (MOF) in a VCHP system. Model calculations show that the MOF–CO2 HCA-HP cycle can release heat at 50% lower pressure than the transcritical CO2 HP cycle and that the COP can be improved by developing a pair of MOF and gases with a step-shaped adsorption isotherm and a large heat of adsorption.
