CARBON DIOXIDE CONCENTRATION CONTROL SYSTEM AND CARBON DIOXIDE CONCENTRATION CONTROL DEVICE

摘要

In order to reduce the energy for and the cost of controlling carbon dioxide (CO2) concentration, a CO2 concentration control system (100-105) is provided, the system being equipped with a measurement part (20) for measuring the CO2 concentration, a CO2 absorption part (30) including a CO2 absorbent (31) that absorbs CO2 at a rate according to the temperature thereof, and a control unit (10) that controls the CO2 absorption rate of the CO2 absorbent (31) by controlling the temperature of the CO2 absorbent (31) using waste heat from a power unit (40).
