Abstract

A ground source heat pump with horizontal ground heat exchanger buried in water-bearing sandy soil was studied. The system was used to heat a public building near the sea in the cold area of China. The slinky heat exchanger was buried under the beach with the sandy soil containing seawater. The heat transfer capacity of soil and heat pump system heating effect were studied. The results showed that the ground source heat pump system with horizontal ground heat exchanger under the beach had a good heating effect. The freezing and flow of seawater in sandy soil were conducive to the stable supply of heat energy, which ensured continuous heating of heat pump system in winter without auxiliary heat sources. The average coefficient of performance of the system during the heating period was guaranteed to be 2.25. Besides that, this GSHP system with HGHE buried in water-bearing sandy soil had obvious economic advantages.

含水砂土中埋置卧式换热器地源热泵研究

对埋在含水砂土中的卧式地源热泵进行了研究。该系统被用于中国寒冷地区靠近海边的公共建筑供暖。细长的热交换器被埋在含有海水的沙质土壤的海滩下。研究了土壤的换热能力和热泵系统的制热效果。结果表明，滩下卧式地源热泵系统具有良好的采暖效果。海水在沙质土壤中的冻结和流动有利于稳定的热能供应，保证了热泵系统在冬季无辅助热源时的连续供热。保证供热期间系统的平均性能系数为2.25。此外，在含水砂土中埋设HGHE地源热泵系统具有明显的经济优势。
