Which outcome increases when a refrigeration cycle’s condenser pressure rises?

A)Compressor work requirement escalates significantly
B)Evaporator coil surface temperature decreases
C)Coefficient of performance elevates marginally
D)Refrigerant mass flow rate diminishes minimally

💡 Explanation

Increased condensing pressure raises the compressor discharge pressure; therefore, the compressor must perform more work during each cycle because of increased compression ratio leading to greater enthalpy change, not minimal shifting of other parameters.
