It can also desorb the adsorbed carbon dioxide. When the indoor carbon dioxide needs to be removed, the indoor air outlet 31 can be switched on through the switching device 40, the indoor circulation is started, and the carbon dioxide in the indoor air is adsorbed by the adsorption component; after the indoor carbon dioxide is removed, the outdoor outlet can be switched on through the switching device 40. The air part 32 starts the outdoor circulation, and the adsorption component desorbs carbon dioxide to discharge the carbon dioxide to the outdoor, so that the adsorption component restores the adsorption capacity of carbon dioxide and maintains the adsorption and removal effect of carbon dioxide.

The carbon dioxide removal module is divided into two operating modes: indoor circulation (carbon dioxide adsorption) and outdoor exhaust (carbon dioxide desorption).

As an example, the switching device 40 is installed in the power unit 20. When the indoor carbon dioxide needs to be removed, the power unit 20 is connected to the indoor air outlet 31, and when the carbon dioxide needs to be discharged, the power unit 20 is turned on. Outdoor air outlet 32 . In this way, when the indoor carbon dioxide needs to be removed, the carbon dioxide removal module can start the indoor circulation, so that the indoor air can pass through the carbon dioxide removal module for adsorption and removal of carbon dioxide, and then discharge it back into the room to improve the indoor air quality; in the case of the need to discharge carbon dioxide , the carbon dioxide removal module can start the outdoor circulation, so that after the carbon dioxide is desorbed from the adsorption component, it is discharged to the outdoor, so that the adsorption component can restore the adsorption capacity of carbon dioxide.

In this way, the carbon dioxide removal module can better match the structure of the air conditioner on-hook, so that the overall structure is more compact and reasonable.

As an example, the outdoor air outlet 32 includes a second pipeline, one end of the second pipeline communicates with the power part 20 , the other end extends to the outdoors and communicates with the outdoors, and the other end has an outdoor air outlet. In this way, after the air flows out of the power unit 20, it is discharged to the outdoors from the outdoor air outlet through the second pipeline.

Optionally, the second pipeline first extends in contact with the casing of the power part 20 , and then extends in a direction away from the power part 20 . In this way, the structure of the outdoor air outlet part 32 and the power part 20 is made compact.

As an example, the adsorption assembly includes adsorption material 50 capable of adsorbing and desorbing carbon dioxide. The adsorbent 50 can separate carbon dioxide from indoor air by adsorbing carbon dioxide, and then release carbon dioxide into the air again by desorbing carbon dioxide. The adsorbent material 50 can be an existing adsorbent material 50 capable of adsorbing and desorbing carbon dioxide.

In some embodiments, the power part 20 includes a fan chamber 21 and a transition chamber 23, the fan chamber 21 is provided with a fan 22, and the air inlet is communicated with the air inlet part 10; the transition chamber 23 is communicated with the air outlet of the fan chamber 21 and is connected with The indoor air outlet 31 is communicated with the outdoor air outlet 32 ; wherein, the switching device 40 is arranged in the transition chamber 23 .

In the centrifugal fan 22 , the gas enters the impeller from the axial direction, changes to the radial direction when the gas flows through the impeller, and then flows out from the airflow outlet of the fan chamber 21 . The air volume and air pressure of the centrifugal fan 22 are relatively large, which can effectively improve the carbon dioxide removal effect on the indoor air.

In some embodiments, the switching device 40 includes a blocking member and a driving mechanism, the blocking member is movably disposed in the transition chamber 23; the driving mechanism is connected with the blocking member, and drives the blocking member in the first position and the second position Rotating between, the blocking assembly closes the airflow inlet of the indoor air outlet 31 in the first position, and closes the airflow inlet of the outdoor air outlet 32 in the second position.

The rotation of the drive shaft of the motor can drive the rotation shaft to rotate, thereby driving the baffle to rotate.

In some embodiments, the airflow outlet of the fan chamber 21 communicates with the bottom of the transition chamber 23 , and the airflow inlet of the indoor air outlet 31 communicates with the top of the transition chamber 23 . In this way, when the switching device 40 is connected to the indoor air outlet 31, the air flow flows out from the top of the fan chamber 21, and then without changing the flow direction, it can directly flow upward into the air inlet of the indoor air outlet 31, and the air volume can be maintained as much as possible and wind pressure, which is conducive to the indoor circulation and improves the effect of removing indoor carbon dioxide.

In addition, the indoor air outlet 31 can send the air after removing carbon dioxide back into the room by blowing the air upward, which can prevent the airflow from blowing directly into the room, thereby improving the user experience.

In some embodiments, the airflow inlet of the outdoor air outlet 32 is disposed on the side wall of the transition chamber 23 . In this way, when the switching device 40 turns on the outdoor air outlet 32 , the air flows out from the top of the fan chamber 21 , and then enters the outdoor air outlet 32 from the air inlet located on the side wall of the transition chamber 23 , and passes through the outdoor air outlet 32 Discharge outdoors. The airflow inlet of the outdoor air outlet 32 is arranged on the side wall of the transition chamber 23, which can be closer to the airflow inlet of the indoor air outlet 31, which is convenient for the switching device 40 to switch on different airflow inlets.
