【摘要】：日趋严重的能源短缺和环境恶化问题制约了社会经济的可持续发展,世界各国都在积极寻找高能效、低排放的低碳经济发展模式,其中利用可再生能源引起了国际社会广泛重视。地源热泵技术作为一种新的暖通空调技术正是利用了浅层地热这一可再生能源,它是建筑节能领域最常用的一种节能技术,在我国得到越来越多的关注,其产业规模日益发展壮大。本文主要研究了地源热泵技术在湖南省的应用情况,以及地源热泵能效测评具体方法研究,第二章至第四章为本文主体章节。首先对湖南省的基本气候、水源、地质情况进行了介绍,然后对地源热泵在湖南省应用的整体情况进行了调查研究,发现湖南省地源热泵建筑应用已经取得了一定成果,部分城市进行地源热泵能效测评的时机已经成熟,但是仍存在一些例如进度滞后、资金短缺等问题,并根据问题提出了一些建议,最重要的是指出下阶段工作重点为研究适合本省省情的能效测评方法和标准。根据湖南省具体的状况,提出了一套适合湖南省的地源热泵能效测评方法,分别针对能效测评形式检查、系统测评和能效评估给出了相关方案；然后编制了一套地源热泵能效短期测试软件,以期帮助没有安装长期监测系统的地源热泵建筑应用项目完成验收工作,并指出该软件可以进一步提高地源热泵能效测评的速度,方便检测人员出具检测报告。此外,还简单介绍了湖南省可再生能源建筑应用示范项目数据监测系统中有关地源热泵数据监测系统相关内容。根据提出的地源热泵能效测评形式检查、短期测试和能效评估的不同方法,对具体的地源热泵项目进行了实例分析,结果表明： (1)本文提出的地源热泵能效测评形式检查方案可以在实际项目中成功应用。 (2)自主研发的地源热泵短期测试软件设计合理,模拟测试实验与实际实验可以相互印证,修改部分程序后可直接运用于地源热泵现场能效短期测试。 (3)具体分析项目的节能效益、环境效益、经济效益虽然低于预期设计值,但是仍然取得了一定节能减排成果,加强项目管理后可取得更大效益。
[Abstract]:The increasingly serious energy shortage and environmental degradation restrict the sustainable development of social economy. Countries all over the world are actively looking for a low-carbon economic development model with high energy efficiency and low emissions.Among them, the use of renewable energy has attracted extensive attention of the international community.As a new HVAC technology, ground source heat pump (GSHP) is a kind of energy saving technology, which uses shallow geothermal energy. It is the most common energy saving technology in the field of building energy saving, and has been paid more and more attention in our country.Its industrial scale is growing day by day.This paper mainly studies the application of ground-source heat pump technology in Hunan Province and the specific methods of energy efficiency evaluation of ground-source heat pump. The second to fourth chapters are the main chapters of this paper.First of all, the basic climate, water source and geological conditions of Hunan Province are introduced, then the whole situation of the application of ground source heat pump in Hunan Province is investigated and studied, and it is found that some achievements have been made in the application of ground-source heat pump buildings in Hunan Province.The time is ripe for some cities to evaluate the energy efficiency of ground-source heat pumps, but there are still some problems, such as lag in progress, shortage of funds, etc., and some suggestions are put forward according to the problems.The most important is to point out that the next stage of the work is to study the energy efficiency evaluation methods and standards suitable for the provincial situation.According to the specific situation of Hunan Province, a set of ground-source heat pump energy efficiency evaluation method suitable for Hunan Province is put forward.Then, a short-term testing software for energy efficiency of ground-source heat pump is developed to help the application project of ground-source heat pump without long-term monitoring system to complete the acceptance work, and it is pointed out that the software can further improve the speed of energy efficiency evaluation of ground-source heat pump.Facilitate the testing personnel to issue a test report.In addition, the data monitoring system related to ground source heat pump in the demonstration project of renewable energy construction in Hunan Province is introduced briefly.According to the different methods of energy efficiency test, short-term test and energy efficiency evaluation of ground-source heat pump, this paper gives an example analysis of the specific ground source heat pump project.The results show that: 1) the energy efficiency test scheme of ground-source heat pump proposed in this paper can be successfully applied in practical projects.2) the short-term test software of ground-source heat pump developed by ourselves is reasonable, and the simulation test experiment and the actual experiment can confirm each other. After modifying part of the program, it can be directly applied to short-term energy efficiency test of ground-source heat pump field.3) the energy saving benefit, the environment benefit and the economic benefit of the project are analyzed in detail, although they are lower than the expected design value, they still have achieved certain results of energy saving and emission reduction, and more benefit can be obtained after strengthening the project management.
