以北京市一个大型储备肉冷库的制冷系统为研究对象,对其全年运行数据和气象参数利用粗糙集理论的约简属性进行分析,以压缩机功率为决策属性,对冷库压缩机各运行参数和气象参数等条件属性进行约简,得到最佳约简属性集。通过约简,将影响参数由10个组约简到2个(排气压力,吸气压力),即排气压力和吸气压力可以表征制冷系统运行状态和压缩机功率,简化了对压缩机能耗的研究和冷库制冷系统节能控制的研究。
Taking a refrigeration system of a large-scale meat refrigerated warehouse in Beijing as the research object, the reduction properties of the annual operation data and meteorological parameters using the rough set theory are analyzed. Taking the compressor power as the decision attribute, the refrigeration compressor operating parameters And meteorological parameters and other conditions to reduce the attributes, the optimal reduction attribute set. By reducing the influence parameters from 10 to 2 (exhaust pressure, suction pressure), the exhaust pressure and suction pressure can characterize the operating status of the refrigeration system and the compressor power, simplifying the compressor performance Research on energy consumption and energy saving control of cold storage refrigeration system.
