- W2809475931 abstract "Abstract With the global energy demand growth, caused by excessive energy consumption and environmental pollution is increasingly serious. And the building energy consumption accounts for about 40% of the global total energy consumption, with great potential for energy saving. Especially in the cold area of northeast China, the summer is very hot and the winter is long and cold. And extreme weather often occurs,the hot and cold polarization is serious. So china cold area need a stable way of energy supply, In the long run, DES systems are an essential part. DES system as a system that can be distributed on the user terminals and supplies energy, is more durable and less prone to massive power outages than a power grid system. To a large extent, it improves the fragility of traditional grid system, avoids the phenomenon of large-scale power outage and solves the problem of long-distance transmission loss.The author mainly describes the application of DES system in the severe cold area of China. Taking the of Shenyang Jianzhu University as an example, the author introduces the DES system including dual-source heat pump unit. This DES system involves a variety of energy forms and energy conversion devices. By promoting the use of low-texergyerature energy of the solar and air or ground, not only low-quality heat needs are met, but also high-quality energy is saved and the overall energy efficiency is improved. The author mainly analyzes the representative winter and summer seasons of Shenyang Jianzhu University Sino-German building, and the energy supply method using distributed energy system is compared with the conventional energy supply method using only the grid.And the Pareto function is introduced which including the best possible trade-offs between the economic and exergy inputs objectives, is obtained by minimizing a weighted sum of the total energy cost and total primary exergy input using branch-and-cut. The results show that energy costs can be significantly reduced through optimized operation of distributed energy systems compared to conventional energy supply systems that use grid-only power supply, and can significantly improve the overall effective energy efficiency to achieve energy saving and emission reduction." @default.
