Abstract
Cold storage merupakan sistem termal kompleks yang berguna sebagai tempat penyimpanan berpendingin dengan dengan tujuan menghindari kebusukan atau kerusakan produk di dalamnya. Salah satu pengimplementasian dari cold storage yaitu multi-storage temperature sebagai pengganti reefer container. Pada penelitian tugas akhir ini akan dilakukan simulasi numerik atau komputasional guna menganalisa kinerja sistem refrigerasi hybrid pada aplikasi multi-storage temperature. Simulasi akan dilakukan menggunakan software Pack Calculation Pro, EES (Engineering Equation Solver), dan Aspen HYSYS dalam memperoleh data-data yang dapat digunakan dalam metode perhitungan akhir. Dengan dilaksanakan penelitian ini, didapatkan bahwa model simulasi terdiri atas dua sistem, yaitu one stage dan multi-evaporator baik secara konvensional maupun hybrid. Hasil simulasi menggunakan perangkat lunak Aspen HYSYS, Pack Calculation Pro, dan EES, bersama dengan perhitungan analitis, menunjukkan peningkatan energi secara umum pada setiap komponen dalam sistem hybrid dibandingkan dengan sistem konvensional. Peningkatan pada kompresor berkisar antara 5,08% hingga 17,79%, pada kondensor 5,43% hingga 18,45%, dan pada evaporator 5,31% hingga 18,82%. Secara keseluruhan, nilai Coefficient of Performance (COP) pada sistem hybrid cenderung lebih tinggi daripada sistem konvensional, menandakan operasional yang lebih efisien. Meskipun perbedaan nilai COP antara kedua sistem tidak signifikan, sistem hybrid memiliki keunggulan dalam penghematan energi karena penggunaan Phase Change Material (PCM) sebagai pengganti fungsi evaporator selama 10 jam. Simulasi menggunakan Aspen HYSYS dianggap paling sesuai, didukung dengan visualisasi yang lebih jelas pada setiap tahap dalam perangkat lunak tersebut, menghasilkan hasil yang lebih presisi

Cold storage is a complex thermal system that is useful as a refrigerated storage area with the aim of avoiding spoilage or damage to the products inside. One implementation of cold storage is multi-storage temperature as a replacement for reefer containers. In this final research assignment, numerical or computational simulations will be carried out to analyze the performance of hybrid refrigeration systems in multi-storage temperature applications. The simulation will be carried out using Pack Calculation Pro, EES (Engineering Equation Solver) and Aspen HYSYS software to obtain data that can be used in the final calculation method. By carrying out this research, it was found that the simulation model consists of two systems, namely one stage and multi-evaporator, both conventional and hybrid. Simulation results using Aspen HYSYS, Pack Calculation Pro, and EES software, along with analytical calculations, show a general energy increase in each component in the hybrid system compared to the conventional system. The increase in compressors ranged from 5.08% to 17.79%, in condensers 5.43% to 18.45%, and in evaporators 5.31% to 18.82%. Overall, the Coefficient of Performance (COP) value for hybrid systems tends to be higher than conventional systems, indicating more efficient operations. Even though the difference in COP values between the two systems is not significant, the hybrid system has the advantage of saving energy due to the use of Phase Change Material (PCM) as a replacement for the evaporator function for 10 hours. Simulation using Aspen HYSYS is considered the most suitable, supported by clearer visualization at each stage in the software, producing more precise results
