摘要:

通过分析厦门某厂典型工业制冷装置的历史运行参数，研究了工业制冷装置的实际运行状况.研究发现，在部分负荷工况下，该厂压缩机和蒸发式冷凝器的负荷匹配不合理，冷凝压力值偏低，造成运行能耗上升.现场实际测试计算表明，该厂通过压缩机和冷凝器的合理匹配，减少一台冷凝器的运行，节能可达5.43 kW.研究发现，冷凝压力过低也会造成能耗增加.在部分负荷工况下冷凝压力的优化控制具有节能效果，并且具有容易操作实现的特点

Abstract:

Actual operating statuses of a typical industrial refrigerating plant in Xiamen were studied based on the analysis of historical operating parameters.It was found that the match between compressors and condensers was inconsequence under part-load conditions.It resulted in a low condensing pressure and high energy consumption.The energy saving was 5.43 kW from the field testing under part-load conditions if the condensing pressure was reasonably controlled by off-cycle of one condenser.It was found that a too low condensing pressure would cause energy consumption increase.Energy saving could be obtained by optimal control of condensing pressure under part-load conditions.It was easy to carry out the operation
