In some embodiments, the fresh air module further includes a mixed air mode. Referring to fig. 2A, in the mixed wind mode, the first sub wind chamber 101 communicates with the second sub wind chamber 102. Wherein, a part of fresh air enters the second sub-air chamber 102 through the first sub-air chamber 101, and the other part of fresh air directly enters the second sub-air chamber 102. Indoor air enters the second sub-air chamber 102 through the second fan air inlet 2021, the second fan air outlet 2022 and the first sub-air chamber 101 in sequence. After the fresh air and the indoor air are mixed in the second sub-air chamber 102, the fresh air and the indoor air are sequentially conveyed into the room through the first fan air inlet 2011 and the first fan air outlet 2012.

The device can adjust the air inlet mode of fresh air based on indoor air quality, is favorable for improving indoor air quality faster, reduces the heat/cold discharge and saves energy. In addition, by only switching the communication states of the first sub-air chamber 101 and the second sub-air chamber 102, different air path communication states corresponding to the mixed air mode and the bidirectional air exchange mode can be formed, so that the air inlet mode of the fresh air module can be conveniently switched.

For example, when the particulate matter content in the room exceeds the standard, a mixed air mode is started, outdoor fresh air is introduced by using the first fan, the indoor air quality is continuously improved, and the comfort level of a user is ensured. Simultaneously, utilize the second fan to draw indoor air, mix the back with outdoor new trend, carry to indoor, utilize the filter element of first fan to get rid of the particulate matter in the indoor air. The first fan is utilized to filter indoor air, so that the content of particles in the indoor air can be reduced, the problem that the content of the indoor particles exceeds the standard is solved, the heat/cold energy is reduced, and the energy efficiency of the air conditioner is improved. Conversely, if the indoor air is discharged by the second fan, although the problem of exceeding the indoor particulate matter content can be solved, the hotter/colder indoor air is discharged, and a part of heat/cold is lost, resulting in an increase in energy consumption of the air conditioner.
