Abstract

Eco reefer container merupakan teknologi yang memiliki perkembangan yang signifikan mengingat sarana utama untuk mendistribusikan produk unggulan setiap daerah. PCM digunakan sebagai media alternatif untuk menjaga suhu di dalam ruang container sehingga komoditi yang dibawa dapat terjaga kualitas dan kondisinya dengan baik, Dalam penelitian ini, PCM di dinginkan oleh evaporator dan digunakan untuk mempertahankan suhu di dalam dan beban yang dibawa saat kondisi discharging. Aplikasi penggunaan material diding prototype eco reefer container ½ ton meliputi tebal dinding colorbond 5,3 mm dan penambahan polyurethane 75 mm bertujuan meredam kondisi suhu luar. Studi ini menganalisis kinerja sistem pendingin eco-reefer container dengan beberapa variasi sistem refrigerasi, kemudian dievaluasi dengan menggunakan simulasi Computational Fluid Dynamics (CFD). Berdasarkan simulasi, kenaikan suhu dari sistem hybrid NaCl 18% + H20 tanpa menggunakan evaporator dari nilai suhu rata – rata -18,82 °C meningkat menjadi nilai suhu rata – rata -18,41 selama 500 (s) yang artinya terjadi kenaikan suhu sebesar -0.,41 °C. Kenaikan suhu sistem hybrid propylene glykol 20% tanpa menggunakan evaporator dari nila suhu rata – rata -18,74 °C meningkat menjadi nilai suhu rata – rata -18,21 °C selama 500 (s) yang artina terjadi kenaikan sebesar -0,53 °C. dari perbedaan keduanya variasi NaCl 18% + H20 lebih setabil suhunya baik dari suhu ruangan rifer, pcm dan suhu kargo dibandingkan dengan propylene glykol 20 % akan tetapi kedua variasi dapat mempertahankan suhu dengan baik untuk menjaga cold storage dari suhu pembusukan.

The eco-reefer container is a technology that has shown significant development, considering its essential role in distributing flagship products to different regions. Phase Change Material (PCM) is used as an alternative medium to maintain the temperature inside the container, ensuring the quality and condition of the transported commodities. In this study, PCM is cooled by an evaporator and used to maintain the temperature inside and the load carried during the discharging phase. The application of materials in the prototype eco-reefer container weighing ½ ton includes a Colorbond wall thickness of 5.3 mm and an additional 75 mm of polyurethane to dampen external temperature conditions. This study analyzes the performance of the eco-reefer container cooling system with various refrigeration system variations, evaluated using Computational Fluid Dynamics (CFD) simulations. Based on the simulations, the temperature increase of the hybrid NaCl 18% + H2O system without using an evaporator, with an average temperature value of -18.82 °C, increased to an average temperature value of -18.41 °C over 500 (s), indicating a temperature increase of -0.41 °C. The temperature increase of the hybrid propylene glycol 20% system without using an evaporator, with an average temperature value of -18.74 °C, increased to an average temperature value of -18.21 °C over 500 (s), indicating an increase of -0.53 °C. From the difference between the two variations, the NaCl 18% + H2O variation shows more stable temperatures in terms of ambient temperature, PCM, and cargo temperature compared to the propylene glycol 20% variation. However, both variations can effectively maintain the temperature to preserve cold storage and prevent spoilage temperatures.
