Abstract

Reefer Container mengalami pertumbuhan dengan pesat. Kebutuhan reefer container ikut tumbuh seiring dengan adanya moda transportasi yang mendukung dari sektor laut dan darat (kapal laut, kereta api, truk), sehingga banyak pelaku yang memiliki kepentingan di sektor logistic paham akan pentingnya penggunaan reefer container dalam menjalankan bisnisnya. Penggunaan Phase Change Material (PCM) sebagai Thermal Energy Storage (TES) merupakan salah satu metode alternatif yang efektif untuk mengatasi kelebihan konsumsi energy dari reefer container dikarenakan karakteristik PCM yang mempunyai kemampuan untuk menyerap dan melepaskan sejumlah kalor laten berdasarkan perubahan temperatur di lingkungan sekitarnya.Dalam aplikasinya, sebelum diletakkan dalam reefer container, PCM diletakkan dalam suatu wadah enkapsulasi ( makroPCM / mikroPCM / nanoPCM ). PCM ini selanjutnya akan dikombinasikan dengan sistem refrigerasi vapour compression / Hybrid Vapour Compression – Phase Change Material (VC-PCM) yang diharapkan bisa menghemat konsumsi daya dari reefer container dengan meringankan tugas kompressor sebagai core dalam sistem pendingin di dalam Reefer Container. Hasil dari penelitian menunjukan bahwa system refrigerasi pada eco – reefer container memiliki low pressure sebesar 2,16 bar dan high pressure sebesar 18,43 bar pada system konvesional setting suhu -20 OC. Coefisien Of Performance (COP) pada setiap kondisi system refrigerasi berbeda – beda. Material PCM yang digunakan mempengaruhi beban yang system refrigerasi sehingga menghasilkan variasi COP pada sistemnya. COP tertinggi di dapatkan pada kondisi hybrid non – equipment dengan komposisi PCM 22% NaCl 35% Glycol. Sedangkan pada kondisi hybrid equipment COP tertinggi dengan menggunakan komposisi PCM 22% NaCl 20% Glycol. Kandungan latent heat setiap PCM yang berbeda – beda menjadikan kondisi beban PCM yang bervariasi sehingga tidak selalu sama. Suhu dalam ruangan prototype eco – reefer container system konvensional di dapatkan angka konstan sebesar – 19 sampai – 20 OC. Pada kondisi konvensional beban yang ditanggung dari system pendingin hanya berupa muatan ikan dengan total 57.6 kg. Penggunaan PCM hanya mampu mempertahankan suhu ruang dibawah -10 OC selama kurang lebih 4 jam. Hal ini dikarenakan properties atau kandungan dari PCM tidak mampu memberikan kinerja maksimal untuk melepaskan kalor latentnya yang digunakan untuk mempertahankan suhu ruang lebih lama.

Reefer Container is experiencing rapid growth. The need for reefer containers is growing along with the supporting modes of transportation from the sea and land sectors (ships, trains, trucks), so that many actors who have interests in the logistics sector understand the importance of using reefer containers in running their business. The use of Phase Change Material (PCM) as Thermal Energy Storage (TES) is an effective alternative method to overcome excess energy consumption from reefer containers due to the characteristics of PCM which have the ability to absorb and release a number of latent heat based on changes in temperature in the surrounding environment. In its application, before being placed in a reefer container, PCM is placed in an encapsulation container (macroPCM / mikroPCM / nanoPCM). This PCM will then be combined with a vapor compression refrigeration system / Hybrid Vapor Compression – Phase Change Material (VC-PCM) which is expected to save power consumption from the reefer container by easing the task of the compressor as the core in the cooling system inside the Reefer Container. The results of the study show that refrigeration system of eco – reefer container has a low pressure 2,16 bar and a high pressure 18,43 bar for confessional setting temperature at -20 OC. The coefficient of performance (COP) in each condition of the refrigeration system is different. The PCM material used affects the load on the refrigeration system, resulting in variations in COP in the system. The highest COP was obtained in nonequipment hybrid conditions with the composition of PCM 22% NaCl 35% Glycol. Meanwhile, in the hybrid equipment conditions, the highest COP was using the composition of PCM 22% NaCl 20% Glycol. The different latent heat content of each PCM makes the PCM load conditions vary so it is not always the same. The indoor temperature of the conventional ecoreefer container system prototype is obtained by a constant number of – 19 to – 20 OC. In conventional conditions, the load borne from the cooling system is only fish with a total of 57.6 kg. The use of PCM is only able to maintain room temperature below -10 OC for approximately 4 hours. This is because the properties or content of PCM is not able to provide maximum performance to release its latent heat which is used to maintain room temperature longer
