Air conditioner, air conditioning system, carbon dioxide removal method, adsorbent and carbon dioxide remover

摘要

An air conditioner 100 used in an air-conditioning target space R including a processing target gas having a carbon dioxide concentration of 5000 ppm or less, including a flow path 10 connected to the air-conditioning target space R, and carbon dioxide contained in the processing target gas The removing unit 10c to be removed is disposed in the flow path 10, the adsorbent 80 containing cerium oxide is disposed in the removing unit 10c, and the adsorbent 80 comes into contact with the gas to be treated, so that carbon dioxide is adsorbed. The air conditioner 100 adsorbed to 80.
