The fresh air module 100 is arranged on one side of the heat exchange fan 220 and the heat exchanger 230 of the wall-mounted air conditioner indoor unit 200 in the longitudinal direction, and the fresh air module 100 is small in size in the axial direction of the fan, and the second air vent 124 can be arranged corresponding to the side end cover of the shell and is used for air intake through the side end cover, so that the fresh air module 100, the heat exchange fan 220 and the heat exchanger 230 are compact in structure, and the longitudinal length of the indoor unit cannot be excessively increased due to the fact that the fresh air module 100 is additionally arranged.
It is understood that the fresh air module 100 of the present utility model can also be used in other types of air conditioners such as cabinet air conditioning indoor units.
In some embodiments, the air conditioning indoor unit 200 may be provided with a controller and a detection device for detecting the concentration of carbon dioxide in the room.
The controller may be configured to control the fresh air module 100 to operate in the fresh air mode when the carbon dioxide concentration detected by the detection device is greater than a preset concentration threshold.
The controller may be further configured to control the fresh air module 100 to switch to the air exhaust mode when the operation time of the fresh air mode is greater than the first time threshold, and to re-compare the indoor carbon dioxide concentration with the preset concentration threshold when the operation time of the air exhaust mode is greater than the second time threshold, so as to implement bidirectional ventilation and rapidly update the indoor air.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
