Claims11
A carbon dioxide recovery apparatus comprising:
- a container having air permeability and disposed outside an elevator cab or outside a counterweight in a hoistway of the elevator cab;
- and
- an adsorbent adsorbing carbon dioxide and contained in the container, wherein
- when the elevator cab and the counterweight move up and down, air in the hoistway enters the inside of the container and air in the container is discharged into the hoistway.

A carbon dioxide recovery method comprising:
- a filling step of filling an adsorbent adsorbing carbon dioxide into a container having air permeability and disposed outside an elevator cab or outside a counterweight in a hoistway of the elevator cab;
- an adsorption step of causing carbon dioxide to be adsorbed onto the adsorbent by raising and lowering the elevator cab to bring the adsorbent into contact with air containing carbon dioxide;
- and
- a recovery step of recovering the adsorbent which has adsorbed carbon dioxide from the container, wherein
- in the adsorption step, air in the hoistway enters the inside of the container and air in the container is discharged into the hoistway.
