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