摘要
为探究严寒地区地源热泵技术的应用情况及节能效果,选取吉林省63个可再生能源建筑应用示范项目进行了实测,对地源热泵系统的应用情况和节能性能进行了计算分析.结果表明,所检测项目平均性能系数和能效比均满足规范的限值要求,地源热泵技术取得了良好的节能效果.对于在检测中发现的"大流量、小温差"等问题,给出解决、控制问题的具体办法以及设计运行建议.研究表明,地源热泵系统在严寒地区有较好的适应性.此外,研究中对实测结果进行了整理与分析,可为工程设计和实践提供一定的参考价值.
To explore the application and energy-saving effect of ground source heat pump technology in cold regions, 63 building application demonstration projects of renewable energy in Jilin province were selected and measured. In addition, the application condition and energy-saving performance of ground source heat pump system were calculated and analyzed. The results show that the average performance coefficient and energy efficiency ratio of measured projects can meet the requirements of specification limits, and good energy saving effect can be achieved with the ground source heat pump technology. For the problems of large flow and little temperature difference found in the detection, the ways to solve and control the above-mentioned problems as well as the recommendations for the design and operation were given. The study indicates that the ground source heat pump system has better adaptability in cold regions. Furthermore, the measured results are collated and analyzed in the study, which can provide certain references for both engineering design and practice.
