摘要
卷烟制造工厂在过渡季节需开启制冷机组,为组合式空调机组提供低温冷冻水以确保工房温湿度指标合格,导致制冷机开启周期增长,使整个制冷系统包括制冷机、冷却塔、冷却水泵、冷冻水泵等设备的电耗增加。某卷烟厂在动力中心制冷系统中研究并引进Free cooling(自然冷却)系统。通过系统设计与改造,在过渡季节通过利用冷却塔供冷的方式降温,不仅达到控制工房温湿度指标的目的,同时减少了大功率制冷机组的开启时间,节省了运行费用,提高了设备使用寿命,达到节能降耗的经济运行目的。开展Free cooling系统在制冷系统经济运行中的研究与应用十分必要。
Cigarette factory runs chillers during transitional season to supply low chilled water for AHU to make sure qualified temperature and humidity index,which causes long chillers operation period and increases electric consumption of whole HVAC system including chillers,cooling towers,cooling water pumps,chilled water pumps etc.the article introduces free cooling system and studies its application in HVAC system for cigarette factory.Through system design and renovation,free cooling system using cooling towers to control room temperature and humidity,which reduces operation time of large power chillers,saves operation cost and improves equipment service life to achieve energy saving and consumption reducing.Applying and studying free cooling system in HVAC system is very necessary.
