Shallow Geothermal Energy Application In Engineering Analysis And Development Research Of Beijing Area

Beijing is the capital of our country, now the air quality serious decline, haze weather, the rapid development of economy at the same time, to solve the problem of environmental pollution is the most important issue now. Air conditioning as large energy consumption, to find renewable cold and heat source air conditioning is very necessary.Under this background, the rational use of energy, development of renewable energy technology has become the community consensus, vigorously develop the green renewable energy, especially natural energy has become the mainstream of the field of energy. Shallow geothermal energy and traditional energy (coal, oil, natural gas), shallow geothermal energy resources has a wide distribution, large reserves, renewable, clean and environmental protection, high availability and promising characteristics. Wide distribution, large reserves. Shallow geothermal energy resources are widely distributed in the shallow layer of the earth (<200m) constant temperature zone, not subject to geographical restrictions, huge reserves, because of the shallow geothermal energy mainly comes from solar radiation and the earth gradient temperature increase, they are the renewable energy, development and utilization of shallow geothermal energy does not consume fossil energy, no discharge of pollutants to the atmosphere, no environmental pollution, and belongs to the clean energy.Beijing is located in the cold area, cold area in summer and winter heating needs air conditioning needs, as a typical technology of soil heat pump heating and refrigeration technology using typical natural energy shallow geothermal energy can satisfy this requirement, the characteristics of ground source heat pump with high efficiency and energy saving, green environmental protection and renewable, got the support of national policy and vigorously promote. The soil heat pump is to provide users with the summer air-conditioning refrigeration, air conditioning heating in winter and can offer for the user, so the soil source heat pump can provide the "best air conditioning system in the form of low energy consumption, low operation cost, low emissions, high comfort", to promote the national energy saving and emission reduction play.This article through the design process and test results of a practical example of the ground source heat pump system, the key points in the design of ground source heat pump, energy saving, economy and other basic data; illustrate the practical problem, design points and soil heat pump soil processes of the regularity of soil heat pump and natural energy, shallow geothermal energy application in Beijing area, even in severe cold area and the wider region promotion of ground source heat pump technology has accumulated valuable experience in the design and construction aspects.Finally, through the massive investigation and study to find out Beijing shallow geothermal energy development and utilization of resources; to find Beijing shallow geothermal energy development and utilization of resources engineering problems; to facilitate further development of soil source heat pump projects in Beijing area and to lay the foundation, summarizes the existing project, for future scientific and rational planning, management and guidance development and utilization of shallow geothermal work to lay a solid foundation.
