A two-stage cascade refrigeration system is to provide cooling at -38°C while- operating the high temperature condenser at 1.6 MPa. Each stage operates on the deal vapor-compression cycle. The upper system uses water as its working fluid and operates its evaporator at 5°C. The lower system uses R-134a as its working fluid and perates its condenser at 400 kPa. This system produces a cooling effect of 20kJ/s. Sketch a T-s diagram and evaluate; i) the mass flow rate of R-134a; ii) the mass flow rate of water; and

Question
A two-stage cascade refrigeration system is to provide cooling at -38°C while operating the high temperature condenser at 1.6 MPa. Each stage operates on the ideal vapor-compression cycle. The upper system uses water as its working fluid and operates its evaporator at 5°C. The lower system uses R-134a as its working fluid and operates its condenser at 400 kPa. This system produces a cooling effect of 20kJ/s. Sketch a T-s diagram and evaluate; (i) the mass flow rate of R-134a; (ii) the mass flow rate of water; and (iii) the overall COP of this system.
