Abstract
A filter-drier unit for a refrigerant includes an exterior housing formed of a hard material, and a desiccant material supported within the exterior housing and being formed of a metal-organic framework material having inorganic metal ions and bridging ligands that link the metal ions. The metal-organic framework has a three-dimensional permanently porous structure that has at least one chemically tunable characteristic, such as pore size, pore volume, and surface area.
