Abstract
A system and method to cool the air inside the nacelle and the heat generating components, particularly of an offshore wind turbine is presented. The ambient air first enters an air handling unit near the tower bottom where the airborne water droplets and salt particles are removed. The clean air is then compressed adiabatically, thus increasing the dew point temperature of the water vapor in the air. The high pressure, high temperature air from the compressor is then cooled and dehumidified in a sea water-to-air heater exchanger or an air-to-air heat exchanger. The high pressure air from the heat exchanger then enters the turbine at the tower bottom and flows up to the nacelle where it is allowed to expand adiabatically in a duct. The duct helps direct the resulting cold air over the heat generating components. The cold air can also used to cool these components internally. The warm air ultimately exits the nacelle at the rear top.
