Energy saving of hybrid ventilation in Xichang West Station

 Studies the ventilation and air conditioning scheme of the waiting hall of Xichang West Station by using EnergyPlus software. Combined with the characteristics of meteorological parameters and taking the indoor thermal comfort temperature as the control target, simulates the annual dynamic indoor thermal environment of the waiting hall. Studies the cooling effects of natural ventilation and hybrid ventilation, respectively, and obtains the boundary temperature of monthly hybrid ventilation condition conversion and the system operation strategy. The result of the comprehensive benefit analysis for the whole year shows that the hybrid ventilation system in the waiting hall can reduce the energy consumption 89 488 kWh every year compared with the conventional air conditioning system, the energy saving rate is 24.7%, and the payback period of investment is about 3.74 years.
