Application Research Of Electric Energy Substitution Method Based On Ground Source Heat Pump In Chaoyang District Of Liaoning

In today's society, due to the rapid growth of the rapid development of economy and population, the world ecological damage, environmental pollution and resource hiding spent, has reached the natural ecological environment can withstand the limit. Energy, resources,environmental constraints, has become the bottleneck of the future economic development of various countries. In order to alleviate the huge energy and environmental pressure, energy conservation and emission reduction in recent years has become the new theme of the whole society. People to take positive coping measures, will be included in the national energy development priority areas of renewable energy, so that the energy structure system from the fossil fuel as the main energy in the era of transition to the era of sustainable development of energy.China State Grid Corp actively promote the "dedicated clean energy, building a harmonious society" of the enterprise mission, ground source heat pump as a new type of power replacement technology is gradually promoting. Based on the ground source heat pump technology, the city's sewage has a huge low heat, although this part of the low heat can not be suitable for industrial production, but to the ground source heat pump has brought great potential and excellent heat source. The use of shallow geothermal resources, to provide heating, cooling and hot water to the building of high efficiency and energy saving and environmental protection technology.The theoretical basis for the heat pump comes from the Carnot cycle, and the refrigerator the same, according to the inverse cycle by inputting a small number of high-grade energy(such as electricity), to ground source heat to as low temperature heat source heat pump cooling in summer cooling source, heating in winter heating. In winter, the heat to be able to "take out",raising the temperature, the supply of indoor heating, and store the cold, to prepare for the summer. In summer through the heat pump to the indoor cooling, at the same time, the indoor heat released into the subsurface, heat storage, to prepare for the winter, the earth in the whole cycle plays a regenerator. In this paper, the original ground source heat pump is changed by the underground water source technology, but the "waste to new", the use of sewage treatment after the first grade water as a low temperature cold and heat source. Key the basic principle of ground source heat pump, technical scheme, analysis of energy saving plan for were focused on the design and research, combined with the application of Chaoyang area of ground source heat pump, the of benefit analysis and evaluation, to lay the foundation for the Chaoyang District to promote the ground source heat pump technology, the electric potential can play to practical application.
