建立了地源热泵土壤换热的柱热源模型。经过有限差分的数值模拟,分析了地源热泵系统与冰蓄冷耦合前后地下温度场以及冷却水进出水温度的变化,得出了地源热泵耦合冰蓄冷系统的性能特点和设计要点。
The column heat source model of ground-source heat pump soil heat exchange was established. After finite difference numerical simulation, the change of underground temperature field before and after the coupling of ground source heat pump system with ice storage and cooling and the temperature of inlet and outlet of cooling water are analyzed, and the performance characteristics and design points of GSHP ice storage system are obtained.
