STUDI EKSPERIMENTAL PENGARUH KECEPATAN UDARA DAN BEBAN PANAS TERHADAP UNJUK KERJA ALAT PENUKAR PANAS TIPE COMPACT

ABSTRAK

Penukar panas jenis finned tube banyak digunakan didalam dunia industri dikarenakan karakteristik yang dimilikinya dimana alat penukar panas ini mempunyai kemampuan unjuk kerja yang lebih baik dari pada alat penukar panas lainnya yang dikarenakan adanya sirip sebagai tambahan luasan sehingga akan menambah kemampuan laju perpindahan panas pada alat penukar panas tersebut. Hal ini mendorong adanya penelitian dalam upaya mendapatkan karakteristik perpindahan panas yang optimal. Penelitian ini mengkaji karakteristik yang dikaji adalah aliran yang melintasi tube dengan sususan staggered dimana beban pemanasan yang dipakai adalah air. Dengan memvariasikan debit air panas pada 75 lpm 10 lpm dan 125 lpm sementara kecepatan udara bervariasi dari 09 ms 32 ms. Data yang diambil antara lain temperatur udara air tube pada masing-masing row dan tube pada segmen keempat dan kedelapan dan debit air dan udara. Selain mengkaji alat penukar panas secara keseluruhan untuk menganalisa lebih mendalam maka Analisa juga dilakukan berdasarkan susunan row dan susunan segmen. Diperoleh hasil dari penelitian ini adalah karakteristik perpindahan panas baik secara keseluruhan maupun secara row. Laju perpindahan panas maksimal yang terhadi secara keseluruhan overall yaitu 6920 W pada 125 lpm dengan variasi kecepatan udara 32 ms dan koefisien konveksi 13267 Wm2K. Koefisien perpindahan panas konveksi pada sisi row akan mencapai nilai maksimal pada row kedua. Effisiensi overall fin akan mencapai nilai maksimuam 808 pada debit air 125 lpm dengan variasi kecepatan udara 09 ms. Laju perpindahan panas dan koefisien perpindahan panas konveksi pada segmen 4 berada di tengah-tengah HE mempunyai nilai yang lebih besar dari pada di segmen 8 dekat dinding HE.


ABSTRACT

Heat exchanger type finned tube applied in many industrial because of characteristic owned by It where this heat exchanger has performance better than other heat exchanger which because existence of extended surface so it will add heat transfer in that heat exchanger. This matter push the existence of research in the effort getting optimal heat transfer characteristic. At this research the characteristic which studied isstream get through the Tube bank of where tube by staggered compile where heat load used is water. Massflowrate of hot water variated in 75 lpm 10 lpm and 125 lpm while speed of air have variation 09 ms 16 ms 25 ms and 32 ms. The data which is taken away from the examination is air speed the hot water charge an incoming temperature and go out from hot fluid and good chilled by through entirety and row. Besides studying performance of heat exchanger as whole to analyse more circumstantial hence this analyse also is done pursuant to formation of row and formation of segmen. Result this research are heat transfer characteristic either through entirety and also by row maximal accelerate of heat transfer that happened as overall that is 6920 W at125 lpm with variation of air speed 32 ms and heat transfer coefficient convection 13267 Wm2K. Heat transfer coefficien convection at side row will reach maximal value at second row with massflowrate of water in 125 lpm. Efficiency overall will be reach maximum value 808 at massflowrate of water in 125 lpm with variation of speed air in 09 ms. Accelerate of heat transfer and heat transfer coefficient of convection at fourth segmen residing in middle of HE have better value than at eight segment near by wall of HE
