| 摘 要： | 以湿球温度控制法作为郑州某建筑复合式地源热泵系统控制策略,建立基于TRNSYS的地源热泵系统及其控制系统的模拟平台。在相同钻孔数下模拟不同湿球温度设定值下的系统运行特性,并获取不同钻孔数下维持土壤热平衡的湿球温度设定值。模拟结果表明,钻孔数对湿球温度控制法的湿球温度设定值影响不大,系统的能耗随钻孔数的增加逐渐降低。

| Abstract: | A simulation platform for one hybrid ground-source heat pump system in Zhengzhou and its control system with wet-bulb temperature-based control strategy is developed. The operation characteristics of the hybrid system with different wet-bulb tem- perature set-points and the same boreholes are dynamically simulated. Based on the simula- tion results, the wet-bulb temperature set-points for keeping ground heat balance under different amount of boreholes are obtained. The results show that the amount of boreholes almost does not affect the wet-bulb temperature set-points for this hybrid system and the system energy consumption may decrease gradually when the amount of boreholes increases. |
