电制冷在直燃机系统改造中的运行分析与优化

Operation Analysis and Strategy Optimization of Electric Refrigeration Unit in the Revamp of Direct-fired System

为解决某站房制冷系统制冷效果差、能源消耗大的情况,对其进行了一系列改造。针对改造后系统的实际运行情况进行分析,探讨了不同类型制冷机组联合运行时的节能优化控制策略。最后,分析了系统改造前后制冷季同一运行周期的节能效果,结果表明改造后各项能源耗量均较改造前同期有所降低。

In order to solve the poor refrigeration effect and high energy consumption of the refrigeration system of a station building, a series of modifications were carried out. Based on the analysis of the actual operation of the reformed system, the energy-saving optimization control strategy of different types of refrigeration units was discussed. Finally, the energy-saving effect of the same operation cycle in the refrigeration season was analyzed. The results show that the energy consumption after the system transformation is lower than that in the same period before the transformation.
