By reducing the supply of external fresh air, we achieve significant reduction in energy needed for heating and cooling buildings.
通过减少提供外部新鲜空气，用于给建筑物取暖和降温的能源也明显减少。

Best cooling effect: using the external rotor motor to drive, air can cool the motor directly, which ensures the safe operation of the motor.
最佳冷却效果：采用外转子电机驱动，气流能直接冷却电机，确保电机安全运行。
