Abstract

Sistem teknologi refrigerasi pada container biasanya bertujuan untuk mendinginkan suatu muatan agar suhu tetap terjaga dalam berbagai kondisi. Berbagai inovasi untuk wadah berpendingin terutama pada variasi dinding insulasi. Penelitian ini bertujuan untuk merancang Eco Reefer Container dengan dinding insulasi komposit berbahan polyurethane dan serat kapas, serta menganalisis distribusi temperature pendinginan udara Eco Reefer Container dengan beberapa variasi insulasi komposit menggunakan Software Ansys. Metode yang digunakan dalam penelitian ini adalah metode numerik dengan simulasi FEM (Finite Element Method) untuk mengetahui sebaran temperature pada dinding dan simulasi CFD (Computational Fluid Dynamics) untuk mengetahui sebaran suhu container baik dengan muatan maupun tanpa beban muatan. Simulasi FEM menghitung nilai distribusi suhu pada dinding prototipe Eco Reefer Container ½ ton. Simulasi dilakukan dalam 5 variasi dengan bahan dan komposisi yang berbeda. Simulasi CFD menghitung distribusi suhu di dalam ruang muat prototipe Eco Reefer Container ½ ton. Ruang muat pada Eco Reefer Container ½ ton divariasikan menjadi dua kondisi yaitu tanpa beban dan dengan beban dengan dua material insulasi. Nilai suhu rata-rata terendah berhasil dicapai pada Polyurethane 75% : 25% Serat Kapas. Sedangkan perbandingan data antara hasil simulasi dan hasil eksperimen memiliki nilai suhu yang sedikit berbeda karena metode eksperimen diambil pada kondisi yang berbeda. Pada validasi simulasi dengan eksperimental, dengan dinding insulasi polyurethane 50% : 50% serat kapas hasil yang diperoleh cukup berbeda karena sistem refigerasi pada eksperimen yang perlu peremajaan.

Refrigeration technology system in the container usually intends to cool a load to a keep the temperature in all varies condition. Any innovation for reefer container especially on those insulation walls variation. This research are aims to design the Eco Reefer Container with composite wall insulation that made from polyurethane and cotton fiber, also analyze the temperature air cooling distribution of the Eco Reefer Container with several variation composite insulation using the Ansys Software. The methods are used in this study is a numerical method with FEM (Finite Element Method) simulation to determine the temperature distribution on the walls and CFD (Computational Fluid Dynamics) simulation to determine the temperature distribution of container when within or without load. The FEM simulation calculates the value of the temperature distribution on the walls of the ½ ton Eco Reefer Container prototype. Simulations were carried out in 5 variations with different materials and compositions. CFD simulation calculates the temperature distribution inside the ½ ton Eco Reefer Container chamber. Cargo space in the ½ ton Eco Reefer Container is varied into two conditions, namely without load and within load with two variations of insulation material. The lowest average temperature value was successful in 75% Polyurethane : 25% Cotton Fiber. Meanwhile, data comparison between simulation results and experimental results has a slightly different value of temperature because the experimental method is taken in a different condition. In simulation validation by experimental, with 50% : 50% polyurethane insulation walls, the results obtained were quite different because the refrigeration system in the experiment needed rejuvenation.
