摘要
地热能作为可再生能源,具有能源分布范围广、运行稳定等优势。地热能供暖系统的应用离不开热泵技术。中深层地源热泵系统能够克服浅层地源热泵土壤热失衡问题,且具有出水温度高、能效高等优点。通过综述中深层地源热泵系统的研究现状,分析目前中深层地源热泵在研究和应用中的不足,并指出中深层地源热泵未来的研究方向。
As a renewable energy source,geothermal energy has the advantages of wide range of energy divisions and stable operation.The application of ground source heating systems is inseparable from heat pump technology.The medium and deep ground source heat pump system can overcome the problem of soil thermal imbalance of shallow ground source heat pump,and has the advantages of high outlet temperature and high energy efficiency.The paper reviews the research status of medium and deep ground source heat pump system,analyzes the shortcomings in the research and application,and points out the future research direction of medium and deep ground source heat pump.
