地铁车站空调大系统调控模式的能耗经济性分析

Analysis on the Energy Consumption Economy of Public Areas Air-conditioning System Control Mode in Underground Railway Station

本文简要介绍了地铁空调大系统的负荷特性,分析讨论了地铁空调大系统常用的三种调节控制模式及其对空调系统能耗的影响。在此基础上,以夏季某地铁车站空调大系统在一个典型季度内的运营为例,分析比较了三种调节控制模式的能耗经济性。研究结果表明:恒速电机结合风阀调控不能达到节能目的,且能耗经济性差;变速电机结合风阀调控模式和变频调速调控模式均能达到节能目的,并且,变频调速调控模式能耗经济性优于变速电机结合风阀调控模式。

The load characteristics of public areas air-conditioning system in underground railway station were presented in this paper. The three commonly used regulation and control modes and their influences on the energy consumption of public areas air-conditioning system are all analyzed and discussed. Consequently, the operation of a certain subway public areas air-conditioning system in a season was taken as an example to compare the energy consumption economy for these three modes. The results indicate that, the regulation and control mode of constant speed motor with wind valve shows no energy saving, however, the regulation and control modes of both variable speed motor with wind valve and variable frequency drive are able to save energy. In addition, the energy consumption economy of variable speed motor with wind valve is superior to that of constant speed motor with wind valve, but worse than that of variable frequency drive.
