Abstract:
1. An integrated cooling and climate control system for an offshore wind turbine comprising: a reservoir having a first and second chamber wherein: a plurality of pipes are connected to said first chamber to form an upper cooling circuit which distributes a coolant fluid from said first chamber through heat-generating structures in a nacelle to said second chamber; and a plurality of pipes are connected to said second chamber to form a lower cooling circuit which distributes the coolant fluid from said second chamber through a heat exchange zone to said first chamber; wherein the lower cooling circuit in said heat exchange zone is thermally connected to sea water which serves as a heat sink for heat collected by said coolant fluid in the upper cooling circuit; wherein said system has rotating means to allow pipes connecting the reservoir to the upper cooling circuit to rotate as the nacelle yaws whereby effective circulation of the coolant fluid is maintained when the nacelle yaws; wherein said reservoir is annular and has a hollow center, and an annular divider wall separates the reservoir into said first and second chambers; wherein said annular divider wall is dimensioned to provide an overflow passage between said first and second chambers wherein said passage is adapted to permit coolant fluid to flow between said chambers when the reservoir is tilted.
