Abstract

Beberapa Komiditi sangat mudah membusuk atau rusak karena adanya mikroorganisme Beberapa Komiditi sangat mudah membusuk atau rusak karena adanya mikroorganisme yang dapat mempercepat pembusukan apabila tidak dilakukan perlakuan khusus seperti memberi pendinginan pada suhu rendah. Komoditi ini termasuk kedalam suatu rantai yang dinamakan cold chain yaitu rantai pasokan barang yang mudah rusak dan perlu perlindungan dari paparan suhu yang tidak tepat agar tetap beku, dingin dan kesegarannya terjaga. Untuk menjaga kualitas dipakai sistem refrigerasi yang baik, yang mampu menjaga kestabilan suhu. Kinerja termal Multi-Storage temperature dengan sistem refrigerasi hybrid dengan menggunakan PCM. Metode hybrid dengan PCM ini dapat menurunkan konsumsi listrik pada sistem pendinginan lebih hemat dari sistem konvensional. Hasil dari simulasi yang dilakukan model multi-storage dengan adanya pengarah di bawah evaporator seperti pada model multi-storage hybrid PCM lebih baik untuk penyebaran udaranya, sehingga tidak adanya putaran udara diruangan evaporator dan udara yang keluar dari atas, dimana seharusnya bagian atas evaporator berguna untuk tempat dihisapnya udara panas oleh evaporator. Untuk persebaran udara dinginnya juga baik, karena udara dingin didalam dapat mencapai titik suhu terendahnya yaitu -30˚C pada Freezer dan pada chiller mencapai -5˚C, panas dari luar juga tidak berpengaruh karena diserap oleh lapisan insulasi polyurethane. Adanya tambahan PCM pada kompartemen juga
membantu dalam menahan kenaikan suhu di dalam kedua kompartemen

Some Commodities are very easily rotted or damaged due to the presence of microorganisms. Some Commodities are very easily rotted or damaged due to the presence of microorganisms which can accelerate spoilage if special treatment is not carried out, such as cooling at low temperatures. This commodity is included in a chain called the cold chain, namely the supply chain for goods that are easily damaged and it needs protection from exposure to inappropriate temperatures to keep it frozen, cool and maintain its freshness. To maintain quality, a good refrigeration system is used, which is able to maintain temperature stability. Thermal performance of Multi-Storage temperature with a hybrid refrigeration system using PCM. This hybrid method with PCM is possible reducing electricity consumption in cooling systems that are more economical than conventional systems. The results of the simulation carried out by the multi-storage model with a guide under the evaporator as in the multi-storage hybrid PCM model is better for air distribution, so that there is no air circulation in the evaporator room and air comes out from the top, where the top of the evaporator should be useful for where hot air is sucked in by the evaporator. The distribution of cold air is also good, because the cold air inside can reach its lowest temperature point, namely -30˚C in the freezer and in the chiller it reaches -5˚C, the heat from outside also has no effect because it is absorbed by the polyurethane insulation layer. There is an additional PCM in the compartment too
helps in resisting the rise in temperature inside both compartments
