Q.13 A vapour compression refrigeration system using refrigerant F-12 is employed to produce 8640 kg of ice per day. The condensing and evaporating temperature of refrigcrant are 48°C and-20°C respectively. Saturated liquid leaves the condenser and saturated vapour leaves the evaporator. Compression is isentropic, water at 35°C is used to form the ice. The temperature of ice should be-8°C. Heat flow into the brine tank from surroundings may be taken as 10% of total heat absorbed from water to form ice. Determine the power required to drive the compressor. Take specific heat of ice 2.26 kJ/kg-K. Latent heat of ice = 335 kJ/kg. Specific heat of water = 4.2 kJ/kg-K. The following data may be used: %3D Temp. Pressure Enthalpy Entropy °C bar kJ/lg kJ/kg-K Liquid Vapour Liquid Vapour 48°C 11.64 82.83 205.83 0.2973 0.6802 -20 1.51 17.82 178.74 0.0731 0.7087 Specific heat of vapour 0.82 kJ/kg %3D
3) A cascade refrigeration system uses R22 in the low temp unit and R12 in the high temp unit. The system develops 28 kW of refrigeration at -45°C. The R12 system operates at -12°C evaporating temp and 40°C condensing temp. There is a 10° overlap of temperatures in the cascade condenser. Calculate the power required by R22 compressor, and the power required R12 compressor.
