Perancangan dan Pengaruh Perhitungan Nilai Efektivitas Panas terhadap Alat Penukar Panas Tipe “Shell and Tube Heat Exchanger” dengan Menggunakan Fluida Air - Air

Abstract

A heat exchanger is a tool which is used to transfer an existing heat from one fluid to another fluid. Selection of the appropriate heat exchanger will be able to save the cost of daily operations and maintenance costs. The price of the heat transfer coefficient on the heat exchanger associated with the value of the effectiveness of heat transfer. A heat exchanger is needed in the production process in an industry, so to determine the performance of the heat exchanger needs to be the holding of the analysis. With analysis conducted showed that the heat exchanger is able to generate heat by the standard of work according to the needs desired. Plan activities include literature, design and calculation specifications, making tools, testing tools, proposals lab, lab final project, data analysis, report preparation and testing reports. Activity after the design tool that is practical and data collection outlet temperature of the hot fluid and cold fluid for the calculation of the effectiveness of the heat exchanger. Heat exchangers that are designed namely Heat Exchanger type of shell and tube type U-Ben. Trials tools include running by checking the valve, thermometer, fluid flow and heater. The data collection includes data outlet temperature of the hot fluid and cold fluid. The results obtained by the heat effectiveness values obtained by an average of 27.3093% with the highest effectiveness contained in the variable 4 of 51.4532%.
