Construction method of comprehensive energy efficiency evaluation system of seawater desalination multi-source multi-load system

Abstract

The invention discloses a construction method of a comprehensive energy efficiency evaluation system for a seawater desalination multi-source multi-charge system. The construction method comprises thefollowing steps: analyzing energy efficiency, device energy efficiency, economic energy efficiency, environment and social energy efficiency of the multi-source multi-charge system comprising renewable resources, an energy storage device, refrigeration and heating equipment, a cooling, heating and power load and the seawater desalination device; constructing an energy efficiency index system of the seawater desalination multi-source multi-load system; constructing an energy efficiency index system of the seawater desalination multi-source multi-load system device; constructing an economic energy efficiency index system of the seawater desalination multi-source multi-load system; constructing a seawater desalination multi-source multi-load system environment and social energy efficiency index system; and constructing a comprehensive energy efficiency index system of the seawater desalination multi-source multi-load system by combining the indexes. Therefore, the stable operation of theseawater desalination multi-source multi-load system is ensured, the economic rationality of the system is improved, the renewable resource consumption level, the environmental protection and socialbenefits are improved, and the optimal comprehensive benefits in all aspects are ensured.

Description

Technical field [0001] The invention relates to the field of sea water desalination benefit analysis and comprehensive energy efficiency evaluation system construction, in particular to a method for constructing a sea water desalination multi-source and multi-charge system comprehensive energy efficiency evaluation system. Background technique [0002] As a basic natural resource, water resources have an important impact on human survival and economic development. With the rapid development of my country's market economy and the continuous acceleration of the development of urbanization, water resources, especially freshwater resources, are being used beyond limits, leading to the continuous expansion of supply and demand contradictions. Seawater desalination technology has gradually become an important way to solve the problem of lack of fresh water resources in China by virtue of its simple principle, mature technology, and its advantages that it is not affected by time, space ...
