Displacement ventilation can create better indoor air quality than conventional mixing ventilation and can also save energy for HVAC system. In cold climates, the heat loss at the perimeter zone may cause a cold draught along the window, which disturbs the displacement ventilation air flow. In this paper, four cases were compared under heating conditions by experiments and CFD simulations. In cases 1 and 2, mixing ventilation and displacement ventilation with single-glass window were studied respectively. In case 3, air flow window system was installed with mixing ventilation. In case 4, the air exhaust system through double-glass window was installed with displacement ventilation. The CFD simulations were carried out with the same conditions as the experiments.
