The New Energy-Conservation Technologys Application of the Direct Use of the Low-Temperature Geothermal Resources

Abstract

There are rich geothermal resources in China; the North of China is especially the rich in low-temperature geothermal resources that can be exploited and utilized. This paper describes a geothermal district heating system, which is successfully meeting the needs of the hot users by using the technology of an insulated cistern and at the same time makes full use of the low-temperature geothermal resources. Through this project, the paper discusses the way to use the low-temperature geothermal fluid, analyze the system’s thermodynamic performance and the investment and operating costs, and at the same time, puts forward the solution of the direct use of the low- temperature geothermal resource to promote China’s energy saving and environmental protection technology development and applications.
