Abstract

The invention provides an offshore wind power seawater source heat pump cooling system and a method. A multi-circulation mode is adopted in the system, heat in all heating devices is taken away to a cooling system in a cabin through an evaporation radiator, the cooling system in the cabin efficiently exchanges heat with fluid in the seawater source cooling system in a heat exchanger through heat pump circulation, and the seawater source cooling system exchanges heat with seawater through the heat exchanger; firstly, high-corrosivity seawater is prevented from entering circulating corrosion equipment, and the service life of the equipment is shortened; secondly, different heat exchange fluids can be used in each circulation, so that the heat exchange efficiency is enhanced, and the overall weight is reduced; thirdly, different pressure and circulation modes, such as compression-heat exchange-expansion and the like, can be adopted in each circulation, so that the overall heat exchange efficiency of the system is enhanced; and fourthly, each circulation runs independently, the redundancy is high, and repair and replacement are convenient.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a seawater source heat pump cooling system and method for offshore wind power. Background technique [0002] Wind power generation is a means of generating electricity that utilizes the energy of the wind in the earth's environment and converts it into electrical energy through a wind generator. The power generation process is clean and pollution-free, and it is a completely renewable energy form. At the same time, the global wind resources are abundant. In the environment of reducing carbon dioxide emissions, wind power is the key to adjusting the energy structure. Countries around the world have made great progress in the field of wind power in recent years. At this stage, great achievements have been made in equipment manufacturing, technology research and development, and grid connection. The installed capacity of wind power has continued to expand, the power ...
