地铁车站变风量空调系统能耗模拟分析

以重庆某地铁车站为研究对象,采用EnergyPlus软件建立地铁车站的物理模型和通风空调系统模型,模拟了地铁车站定风量与变风量空调系统的全年能耗情况。通过模拟结果分析,地铁车站通风空调系统全年能耗中,空调能耗约占全年能耗的60～70%,通风能耗约占30～40%;变风量空调系统的全年总能耗比定风量空调系统约减少30%。

Simulation Analysis of Energy Consumption of VAV Air Conditioning System in Subway Station

This paper takes the Chongqing subway station as the research object, uses the EnergyPlus to establish the physical model of the subway station and the model of the ventilation and air conditioning system, and simulates the annual energy consumption of the constant air volume and the variable air volume air conditioning system of the subway station. Through the simulation results, the air conditioning energy consumption accounts for about 60~70% of the annual energy consumption in the ventilation and air conditioning system of the subway station, and the energy consumption of ventilation is about 30~40%, and the total energy consumption of the variable air volume air conditioning system is about 30% less than that of the constant air volume air conditioning system.
