土壤源热泵系统地下温度场的热平衡模拟分析

摘要

以成都来福士广场的土壤源热泵工程为例，采用Fluent6．2软件的TransientSolver模块对该项目的地下温度场进行了模拟计算，分别按照土壤源热泵间歇运行模式和连续运行模式来模拟计算地下温度场20年，从模拟结果可以清楚的看到，间歇运行模式下土壤的热平衡状况良好，突出了地下温度场的取热量和排热量的平衡是保证土壤源热泵系统长期稳定运行的重要因素。%Taking the project of the ground source heat pump on Laifushi Square of Chengdu as the example, the paper adopts the Transient Solver Module of the Fluent6.2 software to have the simulation calculation for the underground temperature field of the program, simulates and cal- culates the twenty years of the underground temperature field by adopting the intermittent operation module and its continuous operation one of the ground source heat pump, and shows from the simulation result that the heat balance of the soil in the intermittent operation module has better heat balance, and highlights the balance of the accumulated heat and the extracted heat of the underground temperature field is important for en- suring the long-term and stable operation of the ground source heat pump.
