摘要
提出季节性自然冷源土壤蓄冷系统,开展严寒地区浅层土壤跨季节蓄能的实验研究,对全年运行状况进行长期监测,并对土壤温度、蓄释冷率和供冷稳定性等实验数据进行细致的分析,得出土壤温度和室外温度的差值与蓄/释冷率之间存在线性关系。研究成果证明严寒地区浅层土壤跨季节蓄冷的可行性与经济性。
A new type of soil cool storage system cross season was presented and corresponding experimental study of the surface soil cool storage season in severe cold climate area was carried out. According to the monitoring of system operating parameters over a full year, the soil temperature, cool charged/discharged rate and the daily cooling characteristics were analyzed. The linear relationship between the cool charged/discharged rate and the difference between daily soil average temperature and air temperature were found. At last, the feasibility and economics of the new system were demonstrated, which showed the system had great energy saving potential in some definite regions.
