| Energy shortage and environmental degradation problems are increasingly serious which have been restricted the sustainable development of social economy, all countries in the world are actively exploring energy-efficient and low emission of low-carbon economic development model, of which using renewable energy draw internationally attention. Ground source heat pump as a new kind of HVAC technology is made use of shallow geothermal which is renewable energy, it is commonly used in the field of building energy saving, which has obtained more and more attention and the industry is increasingly growing in our country.The application of ground source heat pump technology in Hunan province are mainly studied, and the methods about evaluating the energy efficiency of ground source heat pump are researched, chapter 2 to the chapter 4 state the main contents.The climate, source of water and geology of Hunan province are Introduced at first, and then the construction application of the ground source heat pump are investigated and studied, found that the construction application of ground source heat pump has made some achievements in Hunan province, the time is ripe for beginning the work about evaluating the energy efficiency of ground source heat pump in some cities. However, it still has some problems such as progress lag and shortage of funds, some suggestions are given to solve the problems. What’s more, the most important thing is pointed out that the provincial situation energy efficiency evaluation methods and evaluation standard must be created in the future.According to the specific situations of Hunan province, putting forward some methods for evaluating the energy efficiency of ground-source heat pump. Then, giving some related solutions for form inspection, system evaluation and assessment of energy efficiency respectively; In order to helping the complete acceptance work of ground source heat pump systems which are not installed the long-term monitoring system, compiling a set of short-term test software for evaluating the energy efficiency of ground source heat pump, which points out the software can improve the speed for evaluating the energy efficiency of ground source heat pump further, and offer convenience for inspection personnel to issue the test report. In addition, introducing the data monitoring system of renewable energy construction application demonstration project in Hunan province which has related content about ground-source heat pump data monitoring system.According to the methods about evaluating the energy efficiency of ground source heat pump which including form inspection, short test and long term monitoring, some living projects are investigated and studied. The results show that:(1) The methods of form inspection raised in this research can be successfully applied in actual ground-source heat pump systems. (2) The short-term test software which is designed independently for ground source heat pump systems is reasonable, and the simulation testing experiment can be supported by actual experiment, what’s more, after modifying some part program, the short-term test software can be directly applied to texting the energy efficiency of ground source heat pump at the scene. (3) The energy-saving benefit, environmental benefit and economic benefit of the project have lower value than expected, but it still has obtained certain achievements about energy conservation and emission reduction, after strengthening the management of the project, it will obtain greater benefits. |
