A reversible absorption refrigerator consists of a reversible heat engine and a reversible refrigerator. The system removes heat from a cooled space at -15 °C at a rate of 70 kW. The refrigerator operates in an environment at 25 °C. If the heat is supplied to the cycle by condensing saturated steam at 150 °C, determine (a) the rate at which the steam condenses, and (b) the power input to the reversible refrigerator. (c) If the COP of an actual absorption chiller at the same temperature limits has a COP of 0.8, determine the second-law efficiency of this chiller
