| 摘 要： | 建立地源热泵热水器系统的数学模型,并以天津市某别墅地源热泵热水系统的设计与模拟为例,对地源热泵热水器2种方案———容积式地源热泵热水器和直流式地源热泵热水器进行性能分析,并在运行特性、初投资和运行费用方面进行对比。结果表明,相对于传统的热水器,地源热泵热水器具有较好的性能;在相同工况下,直流式地源热泵热水器系统性能系数较高、耗电量较低,但其运行费用和初投资较高。研究结果为地源热泵热水器系统的选择、设计和优化提供参考。

| Abstract: | Establishes the mathematical models of ground source heat pump water heater system（GSHPWHS）,and taking the GSHPWHS for one villa in Tianjin as example,carries out the performance analysis of two schemes,storage-type and direct-type separately,and compares operation characteristics,the initial investment and the operation cost.The results show that the GSHPWHS has better performance than traditional water heaters,and the direct-type GSHPWHS has larger coefficient of performance and less power consumption,but more operation costs and more initial investment than the storage-type one.Provides the reference for the selection,design and optimization of GSHPWHS. |
