3. A refrigeration system utilizing refrigerant R134a as the working fluid is considered. The following
engineering data are provided for your convenience:
i. The system is operated to maintain the refrigerated space at -30°C
ii. The inlet state of the compressor is 60 kPa and -34°C while gaining a net heat of 0.450 kW (Qin)
from the surrounding
iii. The exit temperature and pressure of the compressor are 65°C and 1.2 MPa
iv. The cooling water enters and exits the condenser at 18°C and 26°C with a mass flow rate of
0.25kg/s
v. The exit temperature of the condenser is 42°C
vi. The h₁ = 230.04 kJ/kg, h₂ = 295.18 kJ/kg, h3 =111.28 = h4
vii. The water inlet and outlet enthalpy to cool the condenser are hw1,18°c = 75.47 kJ/kg and
hw2,26°C 108.94 kJ/kg
Determine (a) the actual enthalpy at state 2 with aid of interpolation, (b) the enthalpy at state 4, (c) the
quality of the refrigerant at the evaporator inlet and the enthalpy at state 4, (d) the mass flow rate of the
refrigerant, (e) the waste heat transferred from the refrigerant, the compressor power input, and the
refrigeration load of the thermal system using an energy balance, and (f) the COP of the refrigerator.
