冬季基于地道风空气源热泵系统实验测试

摘要

The cold and heat source of air source heat pump based on the underground tunnel air is heat exchanging air through tunnel. The coefficient of performance of this system is always high because the temperature of underground tunnel air is higher than atmosphere air. The heating capacity and coefficient of performance are tested. Compared the air source heat pump system, the experimental data show that air source heat pump based on the underground tunnel air is efficient manner of building energy saving. The advantage is more obvious when this system applies lower temperatures area in cold winter.%基于地道风的空气源热泵系统是以经地道换热后的空气作为冷热源的热泵系统,这种系统由于室外机环境的改善,其制热效率大大提高.本文对该系统冬季运行时的制热量、输入功率及性能系数进行了实验测试及结果分析.实验数据结果证明基于地道风的空气源热泵系统是一种较高效的建筑节能方式,在温度极低的寒冷地区应用优势愈加明显.
