【摘要】：在全球推廣節(jié)能低碳的前提下,伴隨著日益強大的樓宇系統(tǒng)以及自動化的高速發(fā)展,冷凍機房群控系統(tǒng)在近些年逐漸成為了廠房和商務(wù)樓改造中必不可少的一部分,同時,也成為了建筑能耗改善中的一個重中之重。 本文通過對機房設(shè)備能耗、冷卻塔風機控制流程、泵的運行特點、主機的工況特點等進行了全面的分析,并通過將冷凍水系統(tǒng)、冷卻水系統(tǒng)以及DDC控制系統(tǒng)相結(jié)合,設(shè)計出了一個綜合性的機房群控系統(tǒng)。該系統(tǒng)可實現(xiàn)對空調(diào)系統(tǒng)的冷卻泵、冷凍泵、供回水閥門、冷卻塔、冷水機組、換熱器等設(shè)備運行狀態(tài)的進行監(jiān)視及故障報警的處理,并做出相應(yīng)的節(jié)能分析報告,以便進行長效管理。 通過對一個區(qū)域性集中供冷站自控系統(tǒng)的設(shè)計與調(diào)試,對機房的運行數(shù)據(jù)進行歸總,建立了節(jié)能數(shù)據(jù)庫,使冷凍機房達到最優(yōu)化的運行效果。在保障機房設(shè)備正常運行的前提下,通過機房群控系統(tǒng)對整體設(shè)備進行全面監(jiān)護,通過減少冗余空調(diào)設(shè)備的運行時間,來降低整個機房的能耗。
[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.
