西昌西站复合通风节能研究
Energy saving of hybrid ventilation in Xichang West Station
摘要：
运用EnergyPlus软件对西昌西站候车厅的通风空调方案进行研究，结合气象参数特征，以室内热舒适温度为控制目标，模拟了候车厅的全年动态室内热环境状况，分别对自然通风和复合通风的降温效果进行了研究，得到各月复合通风工况转换的边界温度及系统运行策略。全年综合效益分析结果表明，候车厅采用复合通风系统比常规空调系统每年可减少能耗89 488 kW·h，节能率为24.7%，投资回收期约为3.74 a。
Abstract：
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.
