MODIFIKASI DAN EVALUASI PERFORMA SHELL AND TUBE HEAT EXCHANGER SINGLE PHASE ( MODIFICATION AND PERFORMANCE EVALUATION OF SHELL AND TUBE HEAT EXCHANGER SINGLE PHASE )

Abstract

Tujuan pelaksanaan tugas akhir ini adalah memodifikasi shell and tube heat exchanger dan evaluasi performa shell and tube heat exchanger dengan metode NTU-effectiveness dengan laju alir sisi tube sebesar 3 lpm dan laju alir sisi shell divariasikan sebesar 16, 15, 14 lpm serta pengaturan katup gas pada posisi max, ¾ max, ¼ max, min. Dari hasil pengujian dan analisa data dapat disimpulkan bahwa harga koefisien perpindahan panas keseluruhan berada pada rentang 140,5791W/m2 0C sampai 12,4293 W/m2 0C. Dan nilai kapasitas heat exchanger berada pada rentang 292,54 W sampai 1066,08 W. Kata kunci : kapasitas heat exchanger, koefisien perpindahan panas, shell and tube heat exchanger The aim of this project is to modify a shell and tube heat exchangers and performance evaluation of shell and tube heat exchanger by using NTU-effectiveness method with 3 lpm tube side a flow rate and shell side flow rate was varied at 16, 15, 14 lpm and gas valve settings on the position of max, max ¾, ¼ max, min. The results of the testing and analysis of the data it can be concluded that the overall heat transfer coefficient were in the range of 12.4293 W/m2 0C to 140.5791 W/m2 0C. And the value of the heat exchanger capacity is in the range 292.54 W to 1066.08 W. Keywords: heat exchanger capacity, heat transfer coefficient, shell and tube heat exchanger.
