In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.

In the prior art, the installation of the air conditioner with the fresh air module is constrained by the environment, and the length of the fresh air pipe needs to be changed by matching with the installation environment of an indoor ring. And the longer the length of the fresh air pipe is, the larger the wind resistance of the fresh air pipe is, so that the actual air quantity of the fresh air module is influenced. And the nominal air volume of the fresh air module is measured in a laboratory by connecting a fresh air pipe with standard length, such as a fresh air pipe with standard length of 1 m. When the fresh air module is actually installed, the length of the fresh air pipe may be too long or too short. Therefore, the actual air volume is correspondingly smaller or larger. Therefore, the fresh air module in the prior art has the problem that the difference between the actual air volume and the nominal air volume is large. When the fresh air pipe is long, the wind resistance is large, and the actual air quantity is small. When the fresh air pipe is short, the wind resistance is small, and the actual wind quantity is large.

Referring to fig. 1, fig. 3, fig. 6, and fig. 7, the present invention provides a fresh air module 100, where the fresh air module 100 includes a housing 10, a first wind wheel 31, a second wind wheel 32, and a switching device 20. A first chamber 43 and a second chamber 44 are provided in the housing 10. The housing 10 is provided with a first air inlet 41a, a second air inlet 41b, a first air outlet 42a, and a second air outlet 42b, wherein the first air inlet 41a is communicated with the first chamber 43, and the second air inlet 41b is communicated with the second chamber 44.

A first air inlet 41a and a first air outlet 42a communicated with the first chamber 43, and a second air inlet 41b and a second air outlet 42b communicated with the second chamber 44, wherein a communication hole 45 is further arranged between the first chamber 43 and the second chamber 44. And the first wind wheel 31 and the second wind wheel 32 are respectively and correspondingly arranged in the first chamber 43 and the second chamber 44. A switching device 20 is mounted to the housing 10.

The fresh air module 100 has a series mode and a parallel mode. When the fresh air module 100 is in the series mode, the switching device 20 switches on the communication hole 45 and blocks the first air inlet 41a and the second air outlet 42 b. When the fresh air module 100 is in the parallel mode, the switching device 20 switches on the first air inlet 41a and the second air outlet 42b, and blocks the communication hole 45.

Referring to fig. 4 and 6, specifically, when the fresh air module 100 is in the parallel mode. There are two air flows respectively flowing from the first air inlet 41a and the second air inlet 41 b. Here, the airflow flowing in from the first inlet 41a is referred to as a first airflow, and the airflow flowing in from the second inlet 41b is referred to as a second airflow in the parallel mode. When the fresh air module 100 starts to operate, the first air flow is drawn by the first wind wheel 31, flows into the first chamber 43 from the first air inlet 41a, and then flows out from the first air outlet 42 a. The second airflow is drawn by the second wind wheel 32, flows into the first chamber 43 through the second wind inlet 41b, and then flows out through the second wind outlet 42 b.

Referring to fig. 5 and 7, when the fresh air module 100 is in the series mode, the first air inlet 41a and the second air outlet 42b are blocked, and the communication hole 45 is opened. The airflow flowing in from the second air inlet 41b in the series mode is called a third airflow. The third air flow flows in from the second air inlet 41b, enters the second chamber 44, flows through the second air wheel 32, enters the first chamber 43 through the communication hole 45, flows through the first air wheel 31, and flows out from the first air outlet 42 a.

When the actual length of the fresh air pipe is larger than the standard length of the laboratory, the fresh air pipe has larger wind resistance. The fresh air module 100 is adjusted to be in a series mode by controlling the movement of the switching device 20. The first wind wheel 31 and the second wind wheel 32 are connected in series. At this time, the airflow flowing in from the second air inlet 41b continues to flow through the first wind wheel 31 after being accelerated by the second wind wheel 32, and is further accelerated by the first wind wheel 31. Namely, the fresh air module 100 in the series mode, the third air flow is accelerated by the second wind wheel 32 and the first wind wheel 31 in sequence after flowing in from the second air inlet. Can overcome larger wind resistance. Therefore, the actual air volume of the fresh air module 100 is close to the nominal air volume.

When the actual length of the fresh air pipe is smaller than the standard length of the laboratory, the wind resistance of the fresh air pipe is correspondingly reduced. At this time, the switching device 20 is controlled to adjust the fresh air module 100 to the parallel mode. Compared with the series mode, the fresh air module 100 in the parallel mode has a lower wind speed compared with the series mode because the first airflow and the second airflow are accelerated by only one wind wheel, and the capacity of overcoming wind resistance is correspondingly reduced, so that the actual wind volume is reduced to be close to the nominal wind volume. On the basis of the previous embodiment, the rotating speeds of the first wind wheel 31 and the second wind wheel 32 can be correspondingly reduced, and the actual air volume of the fresh air module 100 is further reduced. Further, at this time, since the rotation speeds of the first wind wheel 31 and the second wind wheel 32 are reduced, the fresh air module 100 having the parallel mode also has the advantage of low noise.
