摘要
为进一步降低地铁站空调系统能耗,根据广州市某地铁车站的具体情况,针对空调冷冻水系统,提出变流量变水温的节能控制策略。使用建筑热力学仿真软件Trnsys建立建筑仿真模型;在建筑模型基础上搭建变冷冻水流量空调系统,作为节能分析的基础对照模型;在变流量空调系统基础上加入不同的变水温控制策略分别搭建出以站台状态参数为计算依据的“经济”控制策略系统和以最不利房间状态参数为计算依据的“全局”控制策略系统,对比分析得出两种控制策略节能率分别为10%和18.8%,其中“经济”控制策略不满足率为2.76%,综合考虑,“经济”控制策略更节能。
To further reduce energy consumption in the subway station air conditioning system,this study proposes an energy-saving control strategy using variable flow rates and variable water temperatures,based on the specific conditions of a subway station in Guangzhou.The strategy involves using variable flow rate and variable water temperature control that is tailored to the specific situation of the station.The Trnsys software,a building thermodynamics simulation tool,is utilized to create a simulation model for the building.The variable chilled water flow air conditioning system is developed based on this model,which serves as the fundamental control model for conducting energy-saving analysis;different variable water temperature control strategies are added to the variable flow air conditioning system to build an“economic”control system based on the station state parameters and an“economic”control system based on the least favorable room state parameters.The comparative analysis shows that the energy saving rate of the two control strategies is 10%and 18.8%respectively,and the unsatisfied rate of the“economic”control strategy is 2.76%.Considering all factors,the“economic”control strategy is found to be more energy-efficient.
