Abstract

In this paper, optimum thermal design of tubular type segmentally baffled heat exchangers which are widely used in the central heating systems with hot water, is investigated taking into account the pressure losses in the exchanger. Optimum thermal design has been carried out with aid of an objective function obtained, taking as basis the Ministry of Public Works Data. This proposed objective function, which is used to determine the design parameters of the exchanger, is a cost function defined in terms of the convection coefficients on the shell and tube sides. In addition, the optimal sizing of an exchanger, according to the optimum convection coefficients obtained at the end of the optimization process, is explained by means of an example.

Özet

Bu çalışmada kaynar sulu merkezi ısıtma sistemlerinde yaygın olarak kullanılan borulu tipte enine perdeli eşanjörlerin, eşanjör içerisindeki basınç kayıplarını da dikkate alarak optimum ısıl tasarımı ele alınmıştır. Optimum ısıl tasarım, Bayındırlık Bakanlığı verileri baz alınarak elde edilen bir amaç fonksiyonu yardımıyla yapılmaktadır. Önerilen bu amaç fonksiyonu, eşanjörün tasarım parametrelerini belirleyen boru ve gövde tarafındaki taşımınla ısı transfer katsayılarına bağlı olarak tanımlanan bir maliyet fonksiyonudur. Buna ek olarak, optimizasyon işlemi sonunda elde edilen optimum ısı transfer katsayılarına göre bir eşanjörün optimum şekilde boyutlandırılması, bir örnek yardımıyla açıklanmıştır
