Patent number: 7967550Abstract: The invention provides a wind turbine wind turbine with two vessels, each being interchangeably in thermal communication with a heating medium which transfers heat from a heat generating structure to the vessel, and with a cooling medium which transfers heat from the vessel to an ambient space. The vessels form a compression structure which form part of a refrigerating circuit which can circulate a working fluid between the compression structure, a condenser and an evaporator. At the evaporator, cooling effect is obtained based on evaporation of a working fluid, and the cooling can be utilized for cooling a heat generating component in the wind turbine.Type: GrantFiled: November 18, 2009Date of Patent: June 28, 2011Assignee: Vestas Wind Systems A/SInventors: John K. Grevsen, Srikanth Narasimalu, Jesper Nyvad, Poul Torben Tietze, Anand Bahuguni, Krishnamoorthi Sivalingam
