Abstract

Abstract—The increasing number of perishable product distribution leads to the increasing number of the use of cold storage/container vessels. It is needed to keep the temperature suitable for meat, fish, fruits and vegetables. In the cold chain industry, some steps and long time needed in the storing and distribution process cause the expense of storing products large. For example storaging the meat in low temperature is highly recommended to keep the meet in the best condition before it's consumed, the best temperature of the meat is -12oC to avoid Microbes growing. And the best temperature to inhibit cellular metabolism inside animals body is -18oC. Maintain the temperatures of fruits or meat in a certain condition is aimed to keep the product in the best quality. To maintain temperature in a good condition is necessary to choose proper cold storage. But mostly of Cold Storages are using HCFC (Hydro Chloro Flouro Carbon), HFC (Hydro Flouro Carbon), NH3 (Ammonia), air and carbon dioxide for the refrigerant. Despite it is natural refrigerant types, but HCFC, HFC and NH3 have toxic, corrosive and flammable impact. Knowing those refrigerants are dangerous, implementation of advance technology which reduce the use of such products is needed. One of advance technology that can be implemented to solve the problems are using Phase Change Material (PCM) for the support of conventional refrigerant. This material makes refrigerants do not need to work in continuous state because the ability of materials to store heat energy or release it. Besides, these organic materials are not toxic. Selected material in this study is salt PCM, it’s properties to sustain temperature in the lower degrees and the ease to obtain the materials make the materials become priority to choose as refrigerant support. From several experiments have been done that salt-water solutions materials have good capability to maintain temperature in certain condition and can reduce of waste energy in compressors.
