A wind turbine comprising at least a blade () having an aerodynamic profile with a leading edge (), a trailing edge () and suction and pressure sides between the leading edge () and the trailing edge () that includes an anti-noise device () placed on the suction side formed by elements () that modify the frequency spectra of the boundary layer noise. Preferably the anti-noise device () is placed on the suction side between two sections corresponding to chord positions in the range of 40%-95% of the chord length, measured from the leading edge ().

Wind turbine blade with anti-noise devices

A climatisation system for wind turbines which comprise: a first heat exchanger () in the nacelle () for exchanging heat with an element of the nacelle for which the temperature needs to be controlled; a second heat exchanger () outside the nacelle () for exchanging heat with a first exchange unit (); a first section () of a climatisation circuit for: connecting the first heat exchanger () with the second heat exchanger (); circulating a liquid coolant between the first heat exchanger () and the second heat exchanger (); impulsion units () for circulating the liquid coolant on the first section () of the climatisation circuit; a shut off valve (); and expansion tank (); an expansion valve () between the first heat exchanger () and the second heat exchanger ().
