SSC SSC JE Mechanical 2025 Mock Test Series (Paper 1 & Paper 2) Refrigeration and Air Conditioning Refrigeration Cycles and Devices
A refrigeration plant cycle has the following state points:
• Enthalpy after compression = 425 kJ/kg,
• Enthalpy after throttling = 125 kJ/kg,
• Enthalpy before compression = 375 kJ/kg.
Then the COP of refrigeration plant is:
