寒冷地区地源热泵应用效果研究

Application Effect of Ground Source Heat Pump in Cold Area

"十一五"和"十二五"期间,全国大力发展地源热泵技术。由于影响该技术应用效果的因素众多,不同的项目应用效果不大一样。为深入了解寒冷地区地源热泵技术的运行效果及发展潜力,选择某寒冷地区地源热泵典型项目进行实地走访调研。从5个具体项目实例的适宜性、应用效果、运行情况、经济性来分析该地区地源热泵的应用优势,并与全国各地地源热泵项目的应用水平及特点进行对比,指出现阶段阻碍地源热泵发展的问题及解决方法,为今后寒冷地区地源热泵系统的设计运行等方面提供参考依据。

During the＂Eleventh Five-Year Plan＂and the＂Twelfth Five-Year Plan＂Period,the technology of Ground Source Heat Pump （GSHP） developed fast across the country. Because there are many influence factors on the technology, different projects show various utilizing effects. To further understand the running effect and development potential of GSHP technology in cold area, some typical projects are se-lected in cold area to research. The advantage of GSHP in this region is analyzed, based on the suitability, application effect, operation and economy of five specific project examples. And levels and characteristics of the GSHP projects are compared throughout the country to expound present problems hindering in the development of the ground source heat pump with solutions,providing references on the design and opera-tion GSHP system in cold area in the future.
