摘要
本文利用地源热泵空调系统的全年运行实验结果,研究了地埋管换热器与周围土壤的热量交换以及土壤的温度变化。实验结果与理论计算表明,由于采用热回收技术,该系统可减少33 7%的热量排放。连续运行一年后,土壤的平均温升为0.7℃,解决了夏热冬冷地区地源热泵空调系统的土壤热平衡问题。
This paper uses operating results of the whole year of the ground source heat pump of air-conditioning system, and studies the heat transfer between the ground heat exchanger with the surrounding soil. At the same time, the paper studies the temperature distribution of the heat exchanger＇s surrounding soil. The experimental and theoretical results show that as the system utilizes the heat recovery technology, the system reduces about 33.7% heat which discharges to the ground. After the system operates one year continuously, the average temperature of the soil rises 0.7℃. The technology has solved the problem of the soil heat balance in the hot summer and cold winter zone.
