摘要
A shutter particularly for climate control units of the type provided with the free cooling option, comprising at least one first intake (11) for the air that arrives from the outside environment, at least one second intake (12) for the air that arrives from the inside environment, and an outlet (13) on ventilation means (14); the degree of opening of the at least one first intake (11) and the at least one second intake (12) is controlled by flow control means (15), which are moved by an actuator (16) managed by electronic control means (17). The shutter further comprises a first drum (18), which is open onto the ventilation means (14) and is provided with the at least one first intake (11) on its bottom (19) and with the at least one second intake (12) on its lateral surface (20). The flow control means (15) are constituted by a complementarily shaped second drum (21), which is inserted in the first drum (18) and is connected thereto by relative rotation means (22), which are suitable to determine selectively one of the following configurations: -- first intakes (11) closed and second intakes (12) open; -- first intakes (11) open and second intakes (12) closed; -- first intakes (11) and second intakes (12) partially open.
