Model development and software implementation of the aluminum tube and aluminum fin heat exchanger
摘要
Abstract
The fin and tube heat exchanger is the most commonly used type of heat exchangers in household air conditioners.The most direct way to reduce the production cost of fin and tube heat exchangers is the replacement of copper tubes with aluminum tubes.There is a lack of design experience in the aluminum tube and aluminum fin heat exchanger currently,and the development of a simulation model to predict performance can improve design efficiency.This study builds a three dimensional steady state distributed-parameters model of heat exchangers,and the adjacent matrix in graph theory is introduced to describe the complex refrigerant circuitry in heat exchangers.An overall alternating iterative algorithm is adopted,and energy equations for all control volumes and momentum equations of all control volumes are solved dependently to decouple the relationship of conservation equations.A digital simulation design software with an interactive graphical interface is implemented.Experimental validations on prototypes with different combinations of aluminum tubes and aluminum fins are carried out,and the comparison between the experimental results and the simulation results shows that under four working conditions,the deviations of predicted heat transfer,pressure drop inside and outside the pipe are within±5%,±10%,and±10%,respectively.The aluminum tube and aluminum fin heat exchanger model can meet the accuracy requirement of design.关键词
