摘　　要：为解决空调系统采用传统一次回风处理技术在热湿处理过程中存在冷热抵消、再热能耗高等问题,以贵定卷烟厂联合工房为对象,采用DeST建筑热环境设计模拟软件对全年冷热负荷进行模拟分析,以夏季负荷为重点,将其划分为室内负荷、新风负荷和再热负荷,设计了一种采用双温冷水机组的新风独立处理系统。其中,高温冷水机组提供高温冷冻水(16~20℃)用于室内回风降温;常规冷水机组提供低温冷冻水(7℃左右)用于独立新风的降温除湿,利用新风处理室内湿负荷,实现室内温湿分控。将一次回风系统与新风独立系统进行对比测试,结果表明:①与一次回风系统相比,新风独立系统可减少再热等效冷负荷1 449 kW,降低再热负荷27.6%;②与常规冷水机组相比,采用双温冷水机组夏季能耗由108.6万kW·h降低到68万kW·h,节能率达37.3%。该技术可为卷烟厂实现节能减排提供支持。In order to eliminate the“cold-heat offset”and reduce the high energy consumption for reheating in the air conditioning system with conventional air recycling technology,an independent fresh air system based on 2-temperature cooling water unit was designed for the major production building of Guiding Cigarette Factory.The software DeST(Designer’s Simulation Toolkit)was used to analyze the heat and cold loads in a full year,emphatically the load in summer,the load was divided into indoor load,fresh air load and reheated load.The independent fresh air system,includes a high-temperature chiller to provide 16-20℃chilled water for cooling indoor recycling air;and a conventional chiller to provide low temperature(7℃)chilled water for cooling and dehumidifying fresh air.The fresh air is used to deal with indoor humidity so as to control indoor temperature and humidity separately.A comparison test was conducted between the air conditioning systems with conventional recycling air technology and with independent fresh air system.The results showed that:1)Independent fresh air system reduced the equivalent reheated cold load by 27.6%and the reheating energy consumption by 1449 kW.2)Compared with conventional chillers,the energy saving rate of the 2-temperature cooling water unit was 37.3%in summer.This technology provides a support for the energy saving and emission reducing of cigarette factories.
