摘要(Abstract):

针对天津市一地下耦合地源热泵示范工程 ,对所采用的单螺杆式地源热泵机组各部件参数之间的相互关系和运行特征 ,建立了地源热泵运行特性分析模型 ,并对机组性能进行了数值模拟 ;同时 ,结合对该系统的冬季制热工况的实测实验数据 ,对地源热泵冬季典型运行工况进行了实验研究 ,并与模拟分析结果作对比。结果表明 ,模拟和实验结果在数值上和变化趋势上均有较高的吻合度。
The internal relationships among the parameter of each components in heat pump with single screw compressor and its function character in Tianjin District are analyzed. An accurate mathematical model to simulate the dynamic process of the heat pump is established. By the mathematical method and results of experiment, the performance of the ground source heat pump is simulated,and the resulte meet well with the experimental datum.
