土壤源热泵夏季运行中关键参数短期预测的研究

Research on Short-term Prediction of Key Parameters during Operation of Ground Source Heat Pumps in Summer

本文通过TRNSYS软件建立了仿真模型模拟土壤源热泵系统的运行,并借助现场实验数据对仿真模型进行修正,得到了在不同系统加载热流密度和不同土壤初始温度条件下,地埋管出水温度和土壤平均温度的逐时变化规律,同时拟合得出了相应的预测公式并分析了其特性,此预测公式对指导土壤源热泵系统的设计和运行控制具有一定的参考价值。

In this paper, a simulation model through TRNSYS to simulate the operation of ground source heat pumps was established and was corrected with the field experimental data. Under the conditions of different system heat-flow density loads and different soil initial temperatures,the hourly variation rules of outlet water temperature of buried pipes and average temperature of soil were obtained. Meanwhile,a corresponding predictor formula was got through matching,and the characteristics of this predictor formula were further analyzed,which provided some reference for design and operation control of ground source heat pump system.
