按通风系统的工作动力不同，建筑通风有自然通风和机械通风两种

According to the working power of the ventilation system, ventilation natural ventilation and mechanical ventilation are two

自然通风借助“风压”或“热压”等自然压力促使空气流动，而机械通风则是依靠风机产生的压力强迫空气流动

Natural ventilation causes air flow by means of natural pressures such as wind pressure or hot pressing, while mechanical ventilation relies on pressure generated by fans to force air flow

依靠通风机所造成的压力来迫使空气流动进行室外空气交换的方式叫做机械通风。

The way of forcing the air to flow through the outdoor air is called mechanical ventilation by the pressure generated by the ventilators.
