溴化鋰制冷機(jī)遠(yuǎn)程集中監(jiān)控系統(tǒng)研究_畢業(yè)論文-全文預(yù)覽
【正文】 entire system. At the same time, group control of Taiwan in accordance with the refrigerator remote control can set the time automatically cease, or in accordance with the system load automatically cease. From the cooling tower fan stopped by the PLC process automation, PLC in accordance with the 溴化鋰制冷機(jī)遠(yuǎn)程集中監(jiān)控系統(tǒng) 研究 III temperature sensors detect the cooling water return water temperature, the temperature is divided into nine levels, temperature levels in each of the corresponding number of fans to start. At the same time, in accordance with the operation of each typhoon time machine, automatic distribution of the shortest running time running fan priority in order to achieve each of the Typhoon aircraft operating time optimal control, to ensure equality of fan service life.
