In some embodiments, the wall-mounted air conditioning indoor unit may further include an oxygen sensor for sensing an oxygen concentration of the indoor environment. The wall-mounted air conditioner indoor unit adjusts the operation state of the fresh air fan 70 according to the oxygen concentration. For example, in the cooling mode, when the oxygen sensor senses that the oxygen content in the indoor air is lower than 50% of the set value, the fresh air fan 70 automatically turns on the maximum rotation speed to provide enough oxygen content for the indoor. And bidirectional air supply can be realized at the moment, and oxygen-containing fresh air can rapidly flow to an indoor moving area through a reasonable indoor flow field. When the oxygen sensor senses that the oxygen content in the indoor air is lower than 10% of the set value, the fresh air fan 70 is automatically started to the middle speed to provide the oxygen content indoors. When the oxygen sensor senses that the oxygen content in the indoor air is sufficient, the fresh air fan 70 can be automatically turned off. When a user needs a more comfortable indoor thermal environment, the rotating speed of the fresh air fan 70, the rotating speed of the return air fan and the angle of the air deflector can be automatically adjusted, and the standards that the wind speed of a human body activity area is lower than 0.3m/s and the temperature is lower than 3 ℃ fluctuation are realized. Compared with the traditional air conditioner, the air conditioner can realize air flow up, down, left and right, and no dead angle is realized.
When only fresh air is needed without heating or cooling, the oxygen sensor automatically senses the oxygen content of indoor air. The CPU distinguishes the oxygen content into high oxygen content, medium oxygen content and low oxygen content. The rotating speed of the fresh air fan 70 is controlled through an electronic control device, and three gears of high, medium and low are realized. And automatic adjustment is automatically realized according to the scene.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention.
