【摘要】：随着近年来水源热泵系统在我国的各地区应用的逐渐推广,不少项目针对国家的节能政策以及政府补贴不根据自身地质条件盲目的投入并使用,导致了很多失败的项目。很多国内专家学者对该项目的节能及经济性持怀疑态度。本文针对水源热泵的系统特点,对水源热泵系统的原理做了简要介绍,对应用条件及系统方式做了简要分析,对回灌堵塞问题作了分析并介绍了几种解决回灌井堵塞问题的方式及方法。通过两个实际项目的检测作了能源替代量的分析、环境效益分析以及经济效益分析,对水源热泵技术的节能高效以及经济性有了直观定义,以便更好的促进该技术的推广和应用。水源热泵技术应用中的关键技术是地下水的抽取和回灌,本文介绍了水源热泵机组的基本原理,回灌井的种类,以及产生回灌堵塞的原因,总结了的一些解决回灌井堵塞问题的方式及方法；通过对佳木斯技师学院以及中国医科大学附属第二医院的实地检测,以及对室内外温度、井水流量、机组功率的数据整理及分析计算,对上述两个项目做了常规能源替代量分析、环境效益分析以及经济效益的分析。论文最后一部分对水源热泵技术对环境的影响进行了论述,从工程的实际情况角度出发进而确定该技术的节能效益以及环境效益,并对水源热泵技术在未来的发展趋势做了展望。
[Abstract]:With the gradual popularization of the application of water source heat pump system in various regions of China in recent years, many projects have led to a lot of failed projects aiming at the energy saving policy of the state and the use of government subsidies not according to their own geological conditions. Many domestic experts and scholars are skeptical about the energy saving and economy of this purpose. This paper briefly introduces the principle of water source heat pump system, gives a brief introduction to the principle of water source heat pump system, analyzes briefly the application conditions and system mode, analyzes the problem of recharging and plugging, and introduces several ways and methods to solve the problem of plugging in recharge wells. Through two actual items, the analysis of energy replacement quantity and environmental effect are made. The benefit analysis and economic benefit analysis have an intuitive definition of the energy saving efficiency and economy of the water source heat pump, so as to promote the popularization and application of the technology better. The key technology in the application of water source heat pump is the extraction and recharge of the groundwater. This paper introduces the basic principle of the water source heat pump unit and the types of the recharge wells. As well as the causes of the recharge blockage, some methods and methods to solve the problem of recharging wells are summarized. Through the field testing of the Jiamusi technician college and the Second Affiliated Hospital of China Medical University, and the data integration and analysis of the indoor and outdoor temperature, well water flow, and the power of the unit, the above two projects are routinely made. In the last part of the paper, the effect of water source heat pump technology on the environment is discussed, and the energy efficiency and environmental benefits of the technology are determined from the actual situation of the project, and the future trend of the water source heat pump technology is prospected.
