Carbon dioxide recovery system

Abstract

A carbon dioxide recovery system according to the present disclosure comprises: an adsorption unit that recovers carbon dioxide in air using an adsorbent; a transport unit that transports air in an indoor space to the adsorption unit; a heat recovery unit that recovers heat from the air; a separation unit that separates the carbon dioxide from the adsorbent; a first path that extends from the indoor space to the adsorption unit via the heat recovery unit; a second path that extends from the indoor space to the adsorption unit without passing through the heat recovery unit; a switching valve that switches the transport path of the air between the first path and the second path; and a control unit that controls the switching valve.
