High-efficiency energy-storing cold, heat, electricity and water poly-generation system

Abstract

The invention provides a cold, heat, electricity and water poly-generation system capable of comprehensively utilizing wind energy and seawater thermal energy. The cold, heat, electricity and water poly-generation system comprises a wind machine device, a compressed air energy-storing device, a seawater desalinating device and a ground source heat pump device. Tetra-generation of cold, heat, electricity and water can be realized by directly utilizing rich wind energy and seawater thermal energy on islands and in remote coastal areas; under the condition of land isolation, self satisfaction is realized completely; and the system does not need to combust fossil fuel and does not generate pollution gases such as greenhouse gases, sulfide and nitride. The cold, heat, electricity and water poly-generation system converts mechanical energy, which is obtained from wind by the wind machine device, into air internal energy through a compressor, and the energy conversion process is from mechanical energy to internal energy; and compared with energy storage by compressing air by electric drive based on wind power generation, the cold, heat, electricity and water poly-generation system has the characteristics of high energy conversion efficiency, simple structure, investment saving, simplicity in maintenance and the like as part of power generation equipment is omitted.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of renewable energy, and specifically relates to an independent system for comprehensive utilization of wind energy and seawater heat energy for islands and remote coastal areas to realize quadruple production of cold, hot, electricity, and water, so as to overcome the problem that islands are difficult to centralize energy supply , to meet the basic needs of life on islands and remote coastal areas. Background technique [0002] With the development of human beings and society, human footsteps have traveled to every corner of the earth. Since entering the 21st century, with the continuous development of economy and the continuous improvement of living standards, human beings have more and more demands for water, electricity, cold and heat. Especially for some remote areas and islands, it is impossible to obtain resources in this area, and because of the distance from the mainland, it is d...
