深圳地铁一期工程车站公共区空调风系统变频调速工艺设计

Technological Design of Frequency Control of Air Conditioning System for Station Public Area of Shenzhen Metro Stage Ⅰ

就深圳地铁环控设计采用变频调速控制技术必要性和如何采用等问题介绍系统设计单位的设计思路,在屏蔽门制式条件下的节能估算和利弊分析,提供车站公共区空调风系统变频调速工艺设计、控制技术要求和全年空调通风工况转换依据,综合地铁车站环境控制固有特点和空调风系统变频控制的经济性、实用性和可靠性,建议是否可由闭环控制的连续反馈调节改变为时间程序控制,供同行们参考和讨论。

This paper introduces the design concept (including necessity and application) and energy conservation estimate and analysis of advantages and disadvantages of frequency control of air conditioning system in platform screen door condition for Shenzhen Metro Stage Ⅰ. This paper also analyzes the natural characteristics of station environmental control and the economical efficiency, practicality and reliability of frequency control of air conditioning system. It is suggested if continuous feedback adjustment could be replaced by time control.
