WIND ENERGY CONVERSION SYSTEM

摘要

A wind energy conversion system (10) for a building comprises one or more wind powered turbines (12), a pitched roof structure (14) having a first pitch on which the turbines (12) are mounted, and a cover (16) supported on the pitched roof structure (14) above the turbines (12). The cover (16) has a second pitch that is less than the first. The cover (16) and roof structure (14) together create a wind tunnel (28) that directs the wind to flow through the turbines (12). Cowlings (34) are also provided for each of the turbines (12). Each cowling (34) surrounds an upper portion of a corresponding turbine (12). The cowlings (34) are aerodynamically shaped and configured to concentrate air flow across or through a wind rotor (30) of its receptive turbine (12). The cowlings (34) extend in a vertival direction between the cover (16) and the roof structure (14).
