变频控制的地铁站通风空调系统能耗研究

Study on Inverter Control in Subway Ventilation and Air Conditioning System Energy Consumption

本文采用Energy Plus能耗模拟软件,建立地铁车站物理模型以及通风空调系统模型,分别在非变频和变频条件下模拟了屏蔽门内地铁车站空调系统全年能耗情况,对比分析了全年空调系统、风机、水泵的逐月能耗。分析结果显示,无论是否采取变频空调系统,通风空调系统能耗占地铁车站能耗总量的20%~30%左右,是节能的重点之一;风机能耗是通风空调系统能耗的重要组成部分,是节能的重点;水泵能耗相比于风机能耗较少,但也是节能的主要组成部分。

This article uses EnergyPlus modeling the station structure and HVAC system, and simulates the annual energy consumption at inverter-control conditions and constant rate conditions respectively. Analyzing as well as comparing the monthly energy consumption of HVAC, fan and pump, it was gotton that the HVAC system plays an important role in the total energy consumption of the subway state, accounting for 20%-30%. Fan plays a more important role than pump for energy-saving purpose, but both are important for energy goals.
