Geothermal Energy Combined Shallow Geothermal Energy And Renewable Water Heat System Integrated Application Research

Building energy consumption in the proportion of the total energy consumption is very high, most of which are building heating and cooling energy consumption. Many traditional ways of heating produce energy consumption and high pollution, and each year the winter heating has become an obstacle to the smooth implementation of the strategic targets for energy conservation and emissions reduction, so constructing a green low carbon buildings, vigorously and developing clean renewable energy heating refrigeration system are imperative. Facing a tighter resource constraints, the serious situation of serious environmental pollution and ecological degradation, demand for emerging clean renewable energy is more urgent. Resources in the poor of the wind, water and electricity resources reserves less present situation, has a wide distribution, large reserves, localization of geothermal, shallow geothermal energy, renewable water and other renewable new energy are very important in developing strategic position.The above three ways in building heating or refrigeration technology are mature, but in these three ways of single use also has certain limitation, for deep geothermal energy, only suit for heating, can the shallow ground temperature field, water volume and injection conditions, such as recycled water heat affected by water and temperature change is bigger, unstable. Based on the three kinds of clean energy in the process of development and utilization of the shortcomings of the proposed three kinds of energy integration application, three energy advantages into full play, realize new energy application of science and technology innovation, integrated innovation.Through the construction of the demonstrating project, built the deep geothermal energy and shallow geothermal energy and recycled water heat integration application demonstration project. Project will be three kinds of clean energy organic unifies in together for the first time, under the condition of meet the demand of building cooling and heat load of the heating and cooling. Through information monitoring system has realized the system run constantly monitor, data acquisition and analysis, the system of energy use to adjust the proportion to provide reference and basis. The integrated application of three kinds of energy effectively reduces the system cost and ensure the heating and cooling effect, meet the actual needs of the project, reduce the emissions of pollutants, and achieved good social and economic benefits.Success of the project research could promote the integrated application of clean energy in Beijing and around other areas with similar resource conditions, in order to realize the energy utilization efficiency and sustainable development, improving the energy structure and slowly down the substantial contribution of air pollution.
