在夏热冬冷地区,传统式单独运行的地埋管式地源热泵在夏季对土壤的蓄热量大于在冬季的取热量,常年运行会造成土壤热失衡及热泵机组运行效率降低的情况。冷却塔式复合地源热泵系统可利用冷却塔辅助散热,通过分析其组成结构、工作原理和分类特点,确认控制温差和调节冷却塔运行时间等方法可改善热泵运行的工作效率,保持地埋管附近土壤的热平衡,同时在降低热泵机组初投资、运行维护费用,以及减少占地面积等方面优势明显。
In the hot summer and cold winter area, the heat storage capacity of the traditional single ground buried geothermal heat pump in the summer is greater than that in the winter. The perennial operation will cause soil thermal imbalance and reduce the operating efficiency of the heat pump unit. Cooling tower-type ground source heat pump system can use the cooling tower to assist the cooling, by analyzing its composition, working principle and classification characteristics, confirm the control of temperature and cooling tower operating time and other methods to improve the efficiency of heat pump operation, to keep buried pipe Near the heat balance of the soil at the same time reduce the initial investment in heat pump unit, operation and maintenance costs, and reduce the area of obvious advantages.
