Abstract: A carbon dioxide recovery system includes a main controller and unit controllers. The main controller provides guidelines to the unit controllers for a plurality of recovery units. The guideline serves as a guideline for controlling operations of components including an electrochemical cell, a channel on/off valve, a pump, and a channel switching valve. Each one of the unit controllers determines a control content for each one of components based on the guideline.

Abstract: A carbon dioxide recovery system capable of effectively suppressing deterioration of the carbon dioxide adsorption performance of an electrochemical cell is provided. The carbon dioxide recovery system includes a control unit which is configured to perform as an information acquisition unit. The information acquisition unit acquires information about a substance contained in the atmosphere that may adhere to an electrochemical cell. Then, the control device is configured to switch between execution and non-execution of at least carbon dioxide recovery control based on the information acquired by the information acquisition unit.

Abstract: In an adsorption mode, a control device applies an adsorption potential between a working electrode and a counter electrode only during an adsorption time. The adsorption time corresponds to a target carbon dioxide adsorption amount, which an adsorbent can adsorb. In a desorption mode, the control device applies a desorption potential only during a recovery time corresponding to a recovery amount. At this time, the control device acquires an optimum desorption time which is a desorption time associated with a carbon dioxide desorption amount equivalent to a target carbon dioxide recovery amount RVCO2 in a desorption amount change map data. Then, the control device applies the desorption potential only during the optimum desorption time in the desorption mode.

Abstract: In a carbon dioxide recovery system. an electrochemical cell of a recovery device includes a working electrode having an adsorbent capable of adsorbing carbon dioxide, and a counter electrode. A sensor detects a recovery amount of carbon dioxide recovered and sent to a carbon dioxide recovery tank. A controller applies a first potential between the electrodes only for a time period in an adsorption mode. The time period corresponds to a target amount of carbon dioxide that can be adsorbed by the adsorbent. A storage unit stores multiple adsorption-amount change data indicating association between the target amount and the time period. The controller acquires the target amount correlated with the detected recovery amount, acquires the time period by using the acquired target amount, and selects data from among the multiple adsorption-amount change data according to the recovery amount as in-use data for acquisition of the time period.

Abstract: In a carbon dioxide recovery system. an electrochemical cell of a recovery device includes a working electrode having an adsorbent capable of adsorbing carbon dioxide, and a counter electrode paired with the working electrode. A sensor detects a recovery amount that is an amount of carbon dioxide recovered in the recovery device and sent to a carbon dioxide recovery tank. A controller applies a first potential between the electrodes only for an adsorption time period in an adsorption mode such that the adsorbent adsorbs carbon dioxide. The adsorption time period corresponds to a target adsorption amount that is an amount of carbon dioxide that can be adsorbed by the adsorbent. The controller applies a second potential between the electrodes in a recovery mode such that the adsorbed carbon dioxide is desorbed. The controller acquires the target adsorption amount as a correlation value correlated with the detected recovery amount.

Abstract: A control circuit member provided in a motor is disclosed. The motor includes a motor main body having a rotary shaft and a gear housing integrated with the motor main body. The control circuit member includes a circuit substrate on which a rotation detecting element is mounted and a substrate support member. The circuit substrate is accommodated in a circuit accommodating portion in the gear housing. The substrate support member supports the circuit substrate inside the circuit accommodating portion. The control circuit member is configured to be insertable into the circuit accommodating portion along the axial direction of the rotary shaft. The circuit substrate is configured to be arrangeable inside the circuit accommodating portion while being inclined with respect to the axial direction of the rotary shaft, so as to cause the rotation detecting element to approach the detector magnet.
