A vapor-compression refrigeration system using ammonia as refrigerant is to be used to cool 45,000kg of water from 29C to 18C in five hours. The enthalpies in kJ/kg are as follows: evaporator exit= 1471.6, compressor outlet= 1650, condenser outlet= 410.4. Calculate the condenser cooling water requirement in kg/s for 7C temperature rise.
