摘要： The invention relates to the design of a wind turbine with a horizontal rotation axis of a rotor, which has a high energy efficiency at low wind speeds and simplifies its installation directly on a roof of a building.
The wind turbine with a horizontal rotation axis of the rotor has a body (1) in the form of a diffuser, the inlet opening (2) of which has a circular cross-section and the outlet opening (3) has a square cross-section. The hub (4) of the rotor (5) is fixed via radial ribs (6) in the inlet opening (2) of the diffuser (1). The length of the side (7) of the outlet opening (3) of the diffuser (1) and the distance between the inlet opening (2) and the outlet opening (3) of the diffuser (1) are equal to the diameter (D) of the inlet opening (2).
