Discussion on marine semi - enclosed screw - type cooling water unit
舰用半封闭螺杆式冷水机组的探讨
In order to solve this problem , this paper analyzes the fault diagnosis method for chillers using wavelet packet analysis . this paper simulated 9 faults including decreasing of cooling water flow , decreasing of refrigerant and non - condense gas existed and so on . it also analyzed the fault diagnosis technology combined theory and experiments
本论文模拟了冷却水量改变、有不凝性气体、制冷剂流量减小等九个故障,并采用理论分析与实验验证相结合的方法对单螺杆式冷水机组的故障诊断技术进行了研究。
