四川省某卷烟厂中央空调系统节能研究

Research on Energy Saving of Central Air-conditioning System of a Cigarette Factory in Sichuan Province

近年来我国烟草产量逐年增加,但同时该行业能源消耗较大,因此对卷烟企业进行节能改造,提高企业的综合生产能耗水平成为了各地企业的重要任务。以四川省某卷烟厂为研究对象,首先结合相关标准规范对厂房的生产水平进行评估,结果表明企业综合产值较低,而厂房中央空调系统能耗占据企业生产用能的70%左右,因此对该系统进行节能降耗有重要意义。对夏、冬季中央空调系统运行性能分析,发现冷水机组、冷冻水泵以及冷却水泵的开启策略以及设定参数均不合理;最终对设备的运行台数及设定参数给出优化建议,计算出夏、冬季中央空调系统可节省684200kWh的电耗。

In recent years,China's tobacco production has increased year by year.Still,at the same time,the industry's energy consumption is large,so cigarette enterprises carrying out energy-saving transformations to improve the enterprise's comprehensive production energy consumption level has become an essential task of enterprises around the world.This paper took a cigarette factory in Sichuan Province as the object of study,first of all,combined with the relevant standards and norms of the plant to assess the level of production,the results showed that the enterprise's comprehensive production value was low,and the central air conditioning system energy consumption of the plant occupied about 70%of the enterprise's production of energy,so it was essential to carry out energy conservation and consumption reduction of the system.Analysis of the central air-conditioning system operation performance in summer and winter found that the chiller,chilled water pumps,and cooling water pumps on the strategy and set parameters are unreasonable.Ultimately,the number of operating units of the equipment and set parameters to give the optimization recommendations,calculated that the central air-conditioning system in winter and summer conditions can save 684200kWh of electricity.
