                摘要:

                借助CFD软件建立了基于地道风的空气源热泵系统冬季地道风加热升温过程的三维数学模型,并通过实验对模型的精确性进行了验证。根据数值模拟计算结果,分析了地道长度、风速、埋深、结构尺寸等因素对地道风升温系统效果的影响程度。研究结果为地道风升温系统的优化设计提供了依据。

                Abstract:

                Establishes a three-dimensional numerical model of air-source heat pump system based on tunnel air heating process in winter by CFD softwareand verifies its accuracy through experiments. According to the numerical simulation results, analyses the effect of tunnel lengthair velocityburied depth and structure size on the tunnel air heating system, which provides an optimal design basis for tunnel air heating system.
