【摘要】：在全球推广节能低碳的前提下,伴随着日益强大的楼宇系统以及自动化的高速发展,冷冻机房群控系统在近些年逐渐成为了厂房和商务楼改造中必不可少的一部分,同时,也成为了建筑能耗改善中的一个重中之重。本文通过对机房设备能耗、冷却塔风机控制流程、泵的运行特点、主机的工况特点等进行了全面的分析,并通过将冷冻水系统、冷却水系统以及DDC控制系统相结合,设计出了一个综合性的机房群控系统。该系统可实现对空调系统的冷却泵、冷冻泵、供回水阀门、冷却塔、冷水机组、换热器等设备运行状态的进行监视及故障报警的处理,并做出相应的节能分析报告,以便进行长效管理。通过对一个区域性集中供冷站自控系统的设计与调试,对机房的运行数据进行归总,建立了节能数据库,使冷冻机房达到最优化的运行效果。在保障机房设备正常运行的前提下,通过机房群控系统对整体设备进行全面监护,通过减少冗余空调设备的运行时间,来降低整个机房的能耗。
[Abstract]:Under the premise of global promotion of energy saving and low carbon, with the increasingly powerful building system and the rapid development of automation, the group control system of refrigerated machine room has gradually become an indispensable part of the transformation of factory building and commercial building in recent years. It has also become a top priority in building energy consumption improvement. This paper makes a comprehensive analysis of the energy consumption of equipment in the machine room, the control flow of cooling tower fan, the operating characteristics of the pump and the operating conditions of the main engine, and combines the chilled water system, the cooling water system and the DDC control system. A comprehensive group control system of machine room is designed. The system can monitor the operation state of cooling pump, refrigeration pump, backwater valve, cooling tower, water chiller, heat exchanger and so on in the air conditioning system, and can deal with the trouble alarm of the equipment, such as the cooling pump, the freezing pump, the backwater valve, the cooling tower, the chiller and the heat exchanger. And makes the corresponding energy saving analysis report, in order to carry on the long-term effective management. Through the design and debugging of the automatic control system of a regional centralized cooling station, the operation data of the computer room are integrated, and the energy saving database is established. Under the premise of ensuring the normal operation of the equipment in the refrigerator room, the whole equipment is monitored by the group control system of the computer room, and the running time of the redundant air conditioning equipment is reduced. To reduce the energy consumption of the entire computer room.
