A Carnot refrigerator works between the temperature limits of -5°C and 23°C. Calculate the power required to run the refrigerator in case it produces 1000kg of ice per hour at -5°C. Surrounding temperature is 23°C. Assume reversible heat transfer, specific heat of ice as 2kJ/kg K and that of the water as 4.187 kJ/kg K and latent heat of freezing s 335 kJ.kg.
