摘要
介绍了几种常见土壤源热泵U型埋管换热器传热模型,建立了单U型垂直埋管换热器的非稳态传热模型.采用隐式有限差分法对冬季运行工况进行数值模拟,得到了U型埋管出口水温的变化规律及土壤温度场的分布规律.
Base on several common U-tube heat transfer models of ground source heat pump, this paper proposes a transient heat transfer model for single U-tube vertical heat exchanger. Simulates the winter operation condition by adopting explicit finite difference method. The change rules of the exit water temperature of the U-tube and the distribution of ground temperature are obtained.
