摘要
Abstract
Inthepresentstudy,aneconomicanalysismodeloffinandtubeaircoolerunderfrostingconditionwasproposedby considering the heat transfer performance,material costs and the energy consumption.Annual cost of refrigerating capacity per W was set as the objective function;the minimum of the objective function was set as an optimization goal.To solve the model and get the reasonable structural parameters of the air cooler,and analyzes the influence of the structural parameters such as fin pitch,heat exchange tube diameter to the objective function,and verify the model by testing in a cold storage.The experimental and calculat-ed results show that:with the fin pitch increases,the objective function first decreases and then increases,and gets a minimum val-ue when fin pitch is 10mm.With the same fin pitch,the greater of tube diameter,and the greater value of the objective function. By considering the fin pitch,heat exchange tube diameter and tube row number,the objective function value is minimum when fin pitch is 10,heat exchange tube diameter is 9.52 and the tube row number is 6.关键词
