The wide range of use adapts to different geographical environments and seasonal changes.

Optionally, an exhaust fan 161 is provided in the third air outlet channel 160 in this embodiment, and the exhaust fan 161 provides power for air to flow from indoors to outdoors. The exhaust fan 161 is in direct communication with the heat recovery channel 180 , and the exhaust air can directly enter the third air outlet channel 160 after passing through the heat recovery channel 180 . The third air outlet channel 160 is used to communicate with the outdoors, and the exhaust air entering the third air outlet channel 160 can be directly discharged to the outdoors.

The exhaust fan 161 is separately connected to the controller of the environmental control integrated machine. Through stepless speed regulation, the wind speed is automatically calculated according to the user's needs, and the balance of air volume and energy consumption is achieved through the joint control of the controller.

The exhaust fan 161 is arranged in the third air outlet channel 160, so that the structure of the integrated environmental control machine is more compact, thereby reducing the footprint of the integrated environmental control machine. At the same time, the setting of the exhaust fan 161 effectively improves the exhaust power of the integrated environmental control machine, which is beneficial to improve user satisfaction.
