Turbine Room System

In order to prevent erosion from salt spray and rainwater, offshore wind turbines usually concentrate the main heating equipment such as generators, inverters, transformers, gearboxes, cooling cabinets, and control cabinets in enclosed cabins. Although corresponding internal cooling measures are taken for each main heating component, such as circulating liquid cooling to transfer heat to the outside of the cabin, there is still some heat that inevitably enters the cabin through the structural heat transfer surface, causing the air temperature inside the cabin to rise. Especially in harsh summer conditions, the heat transmitted into the cabin through external solar radiation will further increase the thermal load of the cabin. If effective thermal balance measures are not taken, excessive heat accumulation in local areas of the cabin will occur, resulting in high temperature rise and system operation failure.

The system ensures that the equipment is in a normal operating environment: the cabin temperature does not exceed 40 ℃, and the relative humidity is less than 60%.

According to ISO20340-2009, DIN EN ISO12944, and IEC61400-SER-2010, the anti-corrosion level requirements for offshore wind turbines are: external area C5-M, internal area C4.
