Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The recovery efficiency of carbon dioxide decreases when the air flow to the adsorbent is interrupted, such as during the stoppage of an air conditioning device, leading to inefficiencies in carbon dioxide recovery systems.
Innovation Solution
A carbon dioxide recovery system incorporating a blower, a holding unit for the adsorbent, and a control unit that operates the blower when the adsorbent is detected as being in a stopped state, ensuring continuous air flow to the adsorbent even when the main system is not in operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the air conditioning device is stopped to save energy, then energy consumption is reduced, but the carbon dioxide recovery efficiency decreases because air flow to the adsorbent is interrupted
Solution Approach 1:
The control unit is configured to drive the blower in advance when the sensor detects that the adsorbent is held in the holding unit, before the air conditioning device is fully operational. This preliminary action ensures that air flow to the adsorbent is maintained even during system stoppage, preventing efficiency loss while managing energy consumption strategically.
2Productivity
If air flow is continuously directed to the adsorbent to maintain recovery efficiency, then carbon dioxide recovery efficiency is maintained, but energy consumption increases when the system is stopped
Solution Approach 1:
The system employs a sensor that detects whether the adsorbent is held in the holding unit and provides feedback to the control unit. Based on this feedback, the control unit intelligently controls the blower operation, driving it only when the adsorbent is present and needed, thereby maintaining recovery efficiency while avoiding unnecessary energy consumption during system stoppage.
3Loss of energy
If the blower is stopped during air conditioning device stoppage, then energy consumption is reduced, but the carbon dioxide concentration on the adsorbent surface decreases leading to efficiency loss
Solution Approach 1:
The system uses the air conditioning device's own blower component to serve the dual purpose of both air conditioning and carbon dioxide recovery. The control unit leverages the existing blower infrastructure to provide air flow to the adsorbent when needed, eliminating the need for a separate dedicated air flow source and reducing overall energy loss.

AI summary
A carbon dioxide recovery system includes a blower; a holding unit that holds an adsorbent that adsorbs carbon dioxide at a position where an air flow of the blower is received; a sensor that detects that the adsorbent is held in the holding unit; and a control unit that is configured to control the blower, in which the control unit drives the blower when the sensor detects that the adsorbent is held in the holding unit in a state where the blower is stopped.
