基于用能评价体系与能耗模型的工业冷水机组传感器与脏污故障能耗研究
Research on Sensor and Fouling Fault Energy Consumption of Industrial Chiller Based on Energy Consumption Evaluation System and Energy Consumption Model
摘要
Abstract
The energy consumption evaluation system of industrial chiller is established by using the algorithm of decision tree in data mining,and the simulation calculation module of chiller energy consumption is constructed by using Simulink,and the energy consumption of industrial chillers is jointly studied by using the two just established before,and the energy consumption trend of the unit in different degrees of water supply temperature offset and dirty failure is analyzed.The results show that,energy consumption evaluation system based on decision tree algorithm has good practicability in energy consumption diagnosis.The energy consumption simulation model built by Simulink has a good energy consumption simulation calculation function.When cooling water supply temperature deviation of industrial chiller is-1℃,the energy consumption of the unit will increase by 1.41%-8.71%due to the different environment.When the deviation is-2℃,the energy consumption will increase by 8.76%-23.28%.When the deviation is-3℃,the energy consumption will increase by 24.47%-39.56%.The fouling of chiller will increase the energy consumption.When the dirt coefficient is between 0.8 and 0.6,the increase of energy consumption is 19.56%-49.75%.关键词
