[Abstract]:With the development of economy, the acceleration of urbanization and the increasing development of real estate, the building energy consumption in our country is increasing greatly, and the proportion of building energy consumption is also increasing. In the past few hundred years, fossil fuels such as coal have been used. Oil, natural gas and other energy systems have played an important role in the development of society. However, the extensive use of fossil fuels has resulted in the depletion of the earth's resources. With the concept of sustainable development gradually into people's lives, renewable energy such as solar energy, biological energy, ocean energy, water energy, wind energy, Geothermal energy has been paid more and more attention and played an increasingly important role in production and life. With the development of new technology and new technology in modern society, the development and utilization of renewable energy are more and more innovative and pioneering. How to make a smaller impact on the ecological environment while exerting greater energy efficiency is the most concerned topic in the society today. And the use value of heat pump is to do work through electric power with low-grade heat energy. Convert to high grade heat that can be used by people. Ground-source heat pump (GSHP) has become a more and more widely used new HVAC technology in the field of building energy conservation in modern society. In 1997, In 2005, the Ministry of Construction officially listed the ground-source heat pump technology as one of the ten new technologies in the construction industry. In 2006, the Ministry of Construction and the Ministry of Finance jointly issued important documents to support the establishment of special financial subsidies for renewable energy building application projects and to guide the development of renewable energy building application technologies. In order to promote the development scale and speed of its engineering application, ground source heat pump (GSHP) has become the highest level national subject, aiming at solving the common and basic technical problems existing in the current development of ground-source heat pump in China. In 2007, The actual project of ground source heat pump is started in the demonstration city. The technology of ground source heat pump has been gradually approved by all walks of life in our country, which has realized the comprehensive popularization from point to surface, from demonstration project to city level. In this paper, based on the actual project, three existing ground source heat pump projects in severe cold region of China (Changchun City as an example) are investigated on the spot, and the system forms and operation conditions of each project are analyzed. The project initial investment, system operating cost and average annual cost saving compared with conventional energy are compared. Then, the primary energy efficiency and economic benefit of ground-source heat pump system are analyzed. The applicability of ground-source heat pump system is compared with that of traditional coal-fired system, gas system, fuel system and electric system. The advantages and disadvantages of each system are analyzed, as well as the practicability in real life and production. Finally, the application forms and characteristics of ground source heat pump heat exchanger in engineering are analyzed. This paper summarizes the design principle and method of ground source heat pump (GSHP) ground heat exchanger, which is used to evaluate the economy of each design scheme, and summarizes the steps and design flow of optimizing GSHP ground heat exchanger. Through all kinds of analysis and comprehensive consideration of many factors, it is concluded that the ground source heat pump system has good feasibility, obvious development advantage and broad development space in the cold area of our country, and can gradually replace the conventional energy heating. It has become a new type of heating.
