Abstract

A process for producing spherical activated carbon is complex; therefore, an adsorbent that has an effective adsorption amount larger than or equal to that of spherical activated carbon and that is easily produced is desired. An adsorption heat pump uses, as refrigerant, carbon dioxide and uses, as an adsorbent, a metal-organic framework including a metal ion and an organic ligand. The metal-organic framework is, for example, MOF-200.
