Storage time of meats depends on the storage temperature. High storage temperature causes meats rotting quickly. This is become a serious problem in the region with high ambient temperature such as middle east region. Ambient temperature that can be reaches 43oC in this region causes meats only 3-5 days before rotting. Because of that, freezer is needed in order to extend the storage time of meats in that region. <br /> <br /> <br /> High differences between ambient temperature and cabin temperature make the energy consumption of freezer becomes higher. Therefore this research will discuss about design of energy-efficient freezer and operation optimization <br /> <br /> <br /> of freezer in terms of air flow distribution in the cabin. In addition, this research also discuss about refrigerant selection in terms of efficiency, economical, and <br /> <br /> <br /> environmental aspect. <br /> <br /> <br /> The steps of this design consist of collecting data, cooling load calculations, equipment selection, equipment arrangement design, making alternative design for air distribution system, do numerical simulation for each <br /> <br /> <br /> alternatives of air distribution system, air distribution system selection, and cooling process evaluation. The results of this research are freezer COP is 0.92 with the appropriate refrigerant is R-404A and the most optimum air distribution systems are third alternative design.
