Specifically, the first motor 330 and the second motor 340 both adopt outer rotor motors, that is, the motors are installed inside the wind wheel. The first wind wheel 310 and the second wind wheel 320 are independently controlled by the two motors respectively, so that the two wind wheels can operate at different rotating speeds, the air volume of the first air duct 110 and the air volume of the second air duct 210 can be controlled respectively, the temperature of the fresh air flow blown out after the air outlet part 400 is mixed can be better controlled, and the requirements of the air volume and the temperature of different fresh air flows are met. For example, when the air conditioner is in the cooling mode and the outdoor temperature is higher than the indoor temperature, if the temperature of the fresh air flow is higher, the rotation speed can be increased by controlling the first motor 330, so that the air volume of the indoor air flow is increased, the fresh air flow is mixed with more indoor air, the temperature of the fresh air flow blown out by the air outlet part 400 is reduced, and the comfort level of the fresh air flow is improved. In addition, by adjusting the thickness of the first wind wheel 310 and the second wind wheel 320, the proportion of indoor airflow and outdoor airflow in fresh airflow blown out by the air outlet part 400 can be realized, and the design can be performed according to the use requirements of different environments.

In addition, when the rotating speed of the second wind wheel 320 is maintained to be 2000rpm, indoor air flow is increased by changing the rotating speed of the first wind wheel 310, the temperature distribution of indoor mixed air is effectively improved, and the problem of thermal comfort caused by temperature difference when fresh air flow is directly discharged indoors is solved; and through adjusting the proportion of indoor air current in mixing new trend air current, when guaranteeing great new trend amount of wind, reduce the effective distance that new trend air current reaches indoor temperature, solve the pain points such as the new trend air current travelling comfort that the local distribution of temperature uneven leads to is poor and can't perceive.
