A room is kept at -12C by the vapor compression refrigeration cycle using R-134a as the refrigerant. Heat is thrown into the cooling water entering the condenser at a rate of 0.15 kg per second at 20C, and the water comes out at 28C. The refrigerant enters the condenser at 1.2 MPa at 50C and exits as a saturated liquid. If the compressor consumes 2.2k

(c) find the exergy destruction in the condenser. (To= 20C and cpu= 4.18 kJ/kg-C)
