A refrigeration system with R134a as the working fluid is used to maintain a space at 25°C by absorbing heat from water entering the evaporator at 50°C with atmospheric pressure at a rate of 0.065kg/s and exiting at 40°C. The compression has an isentropic efficiency of 75%. The refrigerant exits the evaporator at 20°C with 0.5542 MPa, while the condenser outlet temperature is 3.8°C. Determine the heat exchange in the evaporator.
