ABSTRACT:
A control method and associated component configuration provide cooling for components within a wind turbine structure, such as a tower or nacelle. A recirculating airstream of internal air is established in the structure. For a defined set of operational conditions of the wind turbine that affect a required cooling capacity within the structure, the recirculating airstream is controllably augmented with external air to increase cooling capacity of the recirculating airstream. The amount of external air introduced into the structure is balanced with the amount of relatively hotter internal air within the structure so as to achieve a desired balance of temperature and relative humidity within the structure.
