Selection Criteria for Heat Exchangers for Hot Water Systems

Abstract

The article provides an analysis of existing solutions for choosing shell-and-tube heat exchangers for the needs of hot water supply. When constructing a mathematical model of heat transfer, an approximation of the criterial dependencies describing this process was used. The error estimation of approximating dependencies is presented. The mathematical model of heat balance was used in a numerical experiment. The significance of the influence on the heat transfer efficiency of the parameters of the heat exchanger was established by the results of a numerical experiment. The results of a numerical experiment made it possible to develop criteria for choosing heat exchangers. Keywords: hot water supply, heat exchanger, mathematical modeling, selection criteria
