Abstract

Dalam reefer container, kinerja sistem refrigerasi merupakan bagian terpenting untuk memaksimalkan pengaturan suhu. kemampuan sistem ini untuk menghilangkan panas dari suatu ruangan atau benda dengan tujuan mendinginkannya. Sistem refrigerasi bekerja dengan memanfaatkan siklus pendinginan yang melibatkan pemampatan dan pelepasan gas refrigeran.. Phase Change Material (PCM) adalah material yang menyimpan energi termal dengan memanfaatkan fenomena perubahan fasa alaminya dan menjaga suhu sekitarnya dengan menyimpan panas laten dalam jumlah besar. Panas laten yang disimpan oleh material akan berubah wujud dari padat menjadi cair, atau sebaliknya saat melepaskan panas, bukan perubahan suhu. Studi ini menganalisis kinerja thermal sistem pendingin eco-reefer container dengan beberapa variasi sistem refrigerasi. Simulasi EES (Engineering Equation Solver), Aspen HYSYS, dan EnergyPus dilakukan untuk menganalisa kinerja sistem refrigerasi di dalam container. Pada simulasi EES dan Aspen HYSYS dalam kondisi Evaporator Out suhu yang dihasilkan -20. COP sistem refrigerasi hybrid yang dihasilkan EES 2,545 dan COP yang dihasilkan Aspen Hysys 2,678. Pada simulasi EnergyPlus total site energy sebesar 8724,78 kWh dalam satu tahun dimana konsumsi energi paling besar berada pada cooling system yaitu sebesar 8146,49 kWh. Simulasi EES memiliki hasil yang cenderung mendekati dengan hasil percobaan. Perbedaan nilai COP sebesar 0,197 dibanding dengan hasil COP percobaan, sementara pada hasil simulasi Aspen HYSYS perbedaan nilai COP sebesar 0,683 dibanding dengan nilai COP percobaan. Hasil dari simulasi EnergyPlus didapatkan mendekati dengan hasil percobaan

In a reefer container, the performance of the refrigeration system is the most important part to maximize temperature control. the ability of this system to remove heat from a room or object with the aim of cooling it. The refrigeration system works by utilizing a cooling cycle that involves the compression and release of refrigerant gas. Phase Change Material (PCM) is a material that stores thermal energy by utilizing its natural phase change phenomenon and maintains the surrounding temperature by storing large amounts of latent heat. The latent heat stored by the material will change from a solid to a liquid, or vice versa when releasing heat, not a change in temperature. This study analyzes the thermal performance of the eco-reefer container cooling system with several variations of the refrigeration system. EES (Engineering Equation Solver), Aspen HYSYS, and EnergyPus simulations were carried out to analyze the performance of the refrigeration system in the container. In the EES and Aspen HYSYS simulations in the Evaporator Out condition the resulting temperature is -20. The COP of the hybrid refrigeration system produced by EES was 2.545 and the COP produced by Aspen Hysys was 2.678. In the EnergyPlus simulation, the total site energy is 8724,78 kWh, where the greatest energy consumption is in the cooling system, which is 8146,49 kWh. The EES simulation has results that tend to be close to the experimental results. The difference in the COP value was 0.197 compared to the experimental COP results, while in the Aspen HYSYS simulation results the difference in the COP value was 0.683 compared to the experimental COP value. The results from the EnergyPlus simulation are close to the experimental results
