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 idea of system design unit, energy-saving estimation and pros and cons analysis under the condition of shielded door system, and provides the frequency control of air-conditioning air system in the public area of the station for the necessity and how to adopt the frequency control technology of the VVVS design in Shenzhen Metro. Process design, control technology requirements and year-on-year conversion of air conditioning and ventilation conditions, the inherent characteristics of subway station environment control and air conditioning air conditioning system inverter control economy, practicality and reliability, whether the proposal can be closed-loop continuous feedback control to change to Time program control, for colleagues to reference and discussion.
