| 摘 要： | 针对天津市一实际地下耦合地源热泵示范工程，在对所采用的地源热泵机组中的单螺杆压缩机产品样本数据分析的基础上，具体拟合出了单螺杆压缩机运行的输气系数和绝热效率与压缩比之间的关系式，并与往复活塞式压缩机相比较，结果表明单螺杆压缩机可获得较高的输气系数；同时分析了不同工作温度对单螺杆压缩机循环性能的影响，所得结论为单螺杆热泵系统数值模拟和运行特性分析提供了基础数据。

| Abstract: | The volumetric efficiency and isentropic efficiency curves of single screw compressor in a closed-circuit ground coupled heat pump were fitted.The results demonstrate that the performance coefficient of single screw compressor can excel to that of the reciprocating compressor.The paper also studies the cycle performance of screw compressor under different work temperature,all results provide fundamental datum to numerical simulation and operating analysis of GCHP with single screw compressor. |
