L ULLL ULU LUPUU PROBLEM 2 (40 points) In a refrigeration system in which R-134a is the refrigerant, the R-134a enters the compressor at 200 kPa and -10 °C and leaves at 1.0 MPa and 70 °C. The mass flow rate of the refrigerant is 0.015 kg's, and the power input to the compressor is 1 kW. On leaving the compressor the refrigerant enters a water-cooled condenser at 1.0 MPa and 60 °C and leaves at 0.95 MPa, and 30 °C. The water enters the condenser at 1 bar and 10 °C and leaves at 0.95 bar and 20 °C. Determine: a) The heat transfer rate occurring in the compressor, make sure to indicate the direction b) The rate at which cooling water flows through the condenser. c) The heat transfer rate from the R-134a to the water in the condenser.
