Abstract

Pengiriman kargo dengan jumlah besar baik dari sisi kuantitas maupun dimensi memiliki kondisi yang berbeda dengan pengiriman dalam jumlah kecil. Pengiriman produk segar, dingin, atau beku dalam proses pengiriman dapat dilayani dengan menggunakan reefer container. Saat dioperasikan, reefer container memerlukan konsumsi energi sebesar 3,6kWh/TEUS. Salah satu solusinya adalah menggunakan sistem hybrid kombinasi antara sistem refrigerasi kompresi uap dengan material Phase Change Material (PCM). Dengan menggunakan PCM, temperatur di dalam reefer container dapat di pertahankan hingga beberapa jam pendinginan. Tujuan dari utama dari penelitian ini adalah untuk simulasi kinerja sistem refrigerasi hybrid menggunakan PCM dan distribusi suhu pendinginan pada aplikasi sistem pendingin eco reefer container skala laboratorium. Dari analisa yang dilakukan, didapatkan nilai daya dari simulasi kompresor sebesar 0,3794 kW untuk sistem konvensional, 0,463 kW untuk sistem hybrid PCM NaCl 22% dan 0,411 kW untuk hybrid PCM Propylene Glykol 20%. Nilai COP sebesar 2,560 untuk sistem konvensional, 2,572 untuk sistem hybrid PCM NaCl 22% dan 2,569 untuk hybrid PCM Propylene Glykol 20%. Hasil Simulasi menunjukkan bahan PCM NaCl dan Propylene Glikol mampu menjaga suhu pendinginan rung reefer container dan suhu beban produk.

Cargo shipments in large quantities, both in terms of quantity and dimensions, have different conditions from shipping in small quantities. Delivery of fresh, chilled, or frozen products in the shipping process can be served using a reefer container. When operated, reefer containers require an energy consumption of 3.6kWh/TEUS. One solution is a hybrid system combining a vapor compression refrigeration system with Phase Change Material (PCM) materials. By using PCM, the temperature inside the reefer container can be maintained for up to several hours of cooling. The main objective of this research is to simulate the performance of a hybrid refrigeration system using PCM and the cooling temperature distribution in the application of a laboratory-scale eco-reefer container cooling system. From the analysis performed, the power values obtained from the compressor simulation were 0.3794 kW for the conventional system, 0.463 kW for the 22% NaCl PCM hybrid system, and 0.411 kW for the 20% Propylene Glycol PCM hybrid. The COP value was 2.560 for the conventional system, 2.572 for the 22% NaCl PCM hybrid system and 2.569 for the 20% Propylene Glycol PCM hybrid system. Simulation results show that PCM NaCl and Propylene Glycol are able to maintain the cooling temperature of the reefer container rung and product load temperature.
