挟点温差分析法在水源热泵开发中的应用

Application on Pinch Point Temperature Difference Analysis Method in the Design of Water Source Heat Pump

在水源热泵的研制开发过程中,系统各部件之间的匹配特性以及热泵机组的控制模式成为影响热泵机组运行特性的关键。将挟点温差分析法用于水源热泵的设计,按照制冷、制热两种典型工况下综合效率最佳的原则,力图使热泵主要部件的设计更加合理完善。作为设计方法的一种尝试,可为水源热泵的开发与设计提供一定的参考。

In the development and the design of a water source heat pump, the matching characteristic between heat changers and the control modes become the key factors which are decisive to the performance of the heat pump, the pinch point temperature difference analysis method was applicated on the design of a water source heat pump, aiming at the compositive optimal perform- ance both in typical heating operation and in refrigeration mode, to make the component design more reasonable. As an attempt of new design method, this paper tries to provide some references for the design of water source heat pumps.
