Title:
CO2 ADSORPTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/234131
Kind Code:
A1
Abstract:
This CO2 adsorption device for installing a solid adsorbent (1) comprises: a refrigeration cycle device in which a refrigerant is circulated through a compressor (2), a first heat exchanger (3), a pressure reducer (4), and a second heat exchanger (5); and a control device (9) for controlling the operation of the refrigeration cycle device, wherein the second heat exchanger (5) is installed on the upstream side of an air flow relative to the location where the adsorbent (1) is installed, and during an adsorption operation for adsorbing CO2, the refrigeration cycle device makes the second heat exchanger (5) function as an evaporator to perform a dehumidification operation in which the moisture contained in the air flow is attached to the surface of the second heat exchanger (5).
