Tiivistelmä
The design of heat exchangers for specific applications entails a number of different calculations in order to determine the appropriate dimensions and characteristics for the heat exchanger unit. The relevant equations can be convoluted and often need to be solved in an iterative fashion. Not only is this time-consuming work, but it can also be prone to human errors if performed by hand. A large number of equations for plate heat exchangers have been proposed in the scientific literature, all with different constraints, from which it can be concluded that no commonly accepted method of calculating heat transfer in plate heat exchangers exists.
The purpose of this work is to develop a software application to assist Loval Oy with the dimensioning aspect of designing specifically brazed plate heat exchangers. It will accomplish this by providing a graphical user interface where the user can input information regarding the fluid streams for a specific application, and in return receive an estimate of the heat exchanger unit dimensions necessary. Additionally, experimental data regarding the heat transfer effectiveness will be collected for a number of heat exchanger designs. The data will be used to construct equations that work specifically for the heat exchangers in question in order to ensure that the software application can produce reliable results.
