Abstract

In a country like Myanmar, meat, fruit, vegetables and fish are very affected to microbial and spoilage and required severe preservation methods. One such method is by the use of a plate freezer for the storage of frozen food. The convection freezer could not confront with this higher rate of freezing. The plate freezer consists of two plates connected in parallel. Refrigerant R-134a flows inside the plate type evaporator tube and it can reduce causing the ozone depletion. In this paper, the experimental data of plate freezer were found with the conditions that evaporating temperature is -16.5?C, condensing temperature is 43.7?C and meat temperature is -12.9 ?C. The temperature of meat decreases with increasing time in operation. From calculations, total cooling load of plate freezer is 228 kW, the refrigeration capacity is 297 W (0.0844 TR), refrigerant effect is 125, the mass flow rate is 2.375×10-3 kg/s, motor power is 139 W, the coefficient of performance is 2.98, the mass flow rate is 2.375×10-3 kg/s, evaporator tube length is 9.22m, condenser tube length is 11.77m and capillary tube length is 2.89m.
