Application status and development trend of geothermal energy heating technology

Abstract

With the rapid development of economy, people have higher and higher requirements for the quality of life. The traditional heating mode has serious pollution, uneven temperature, inconvenient installation, poor comfort, large energy consumption and low social benefits. It has been unable to meet people's pursuit of modern quality of life and the construction needs of environment-friendly and resource-saving society. The northern part of China is cold in winter, so it needs indoor heating. As the traditional heating mode has the problems of high energy consumption and environmental pollution, it needs to be updated and optimized. Based on the classification of geothermal energy heating technology, this paper expounds in detail the basic concepts, development and application status of shallow ground source heat pump technology, hydrothermal heating technology and middle-deep buried pipe heating technology. The emergence of geothermal energy heating technology has effectively solved a series of problems existing in traditional heating and has been widely used. In order to explore the heating potential of geothermal resources and its value in the "dual carbon" goal, the endowment and distribution characteristics of geothermal resources in China are briefly described, and the applicable geothermal energy supply models in different regions are given. By summarizing the existing reported research directions and related achievements of geothermal energy heating technology, from the perspective of operation mechanism and application practice, the technology development in this field is prospected.
