In a simple vapour compression refrigeration cycle, the enthalpy at the inlet of the compressor (point 1), discharge of the compressor (point 2), and inlet of the evaporator (point 4) are 260 kJ/kg, 60 kJ/kg, and 180 kJ/kg, respectively. If 2 kg of refrigerant is used to cool the system, then the Coefficient of Performance (COP) of the refrigerator will be:
