碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 95 === This thesis utilizes power line communication structure of LonWorks communication technology, set up a set of instant monitoring systems, Use the power line module of LonWorks communication technology to integration the three-phase digital power meter , thermometer , switch control module,infrared ray module . The surveillance system includes the energy surveillance system, temperature surveillance system, switch control system, infrared ray system, real-time video surveillance system , event scheduler, Data Logger. This surveillance system can be applied to the chiller and cooling tower. This thesis also uses the Taguchi Methods in the field to influence the influence factor of the power consumption of cooling tower, the factor include dry bulb temperature , relative humidity , wet bulb temperature , input water temperature of cooling tower, supply water temperature of cooling tower and RT of cooling tower, and analyse relatively large what influences the proportion of the power consumption of cooling tower for these parameters,and in which level cooling tower can save electricity relatively .By the result, the most powerful control factor of the power consumption is RT , its ton is counted small the power consumption is the lower.
