Abstract

A heat pump can produce a large amount of thermal energy for low- to moderate-temperature heating and cooling from a small amount of energy input. Although vapor compression heat pumps (VCHPs) can achieve a high coefficient of performance (COP), the lack of eco-friendly fluorocarbon refrigerants is a serious problem. An adsorption heat pump is a heat-driven heat pump that does not use fluorocarbon refrigerants but is less compact and has higher installation costs. This perspective 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 MOFs and gases with a step-shaped adsorption isotherm and a large heat of adsorption.
