A control method for an outdoor unit of a fresh air conditioner, and a fresh air conditioner. The control method comprises: obtaining a first inner-side pressure value measured by an inner-side pressure sensor (311) and a first outer-side pressure value measured by an outer-side pressure sensor (312); calculating a difference value between the first outer-side pressure value and the first inner-side pressure value, and marking the difference value as a first pressure difference value; determining whether the first pressure difference value is greater than or equal to a first preset pressure difference value; if yes, determining, according to the first pressure difference value, whether debris is accumulated outside a fresh air filter screen (310); and if the debris is accumulated, switching a rotation direction of a fresh air fan of an outdoor unit (300) of the fresh air conditioner to blow out the debris. By measuring the pressure of the fresh air filter screen (310), the dust/debris accumulation condition o
