Which outcome arises within a refrigeration cycle operating under extremely low evaporating temperatures?

A)Increased compressor power consumption
B)Decreased condenser heat rejection rate
C)Refrigerant breakdown from oil return
D)Excessive superheat at compressor inlet

💡 Explanation

When evaporating temperature is extremely low, the pressure ratio in the compressor increases substantially because the compressor works harder to achieve condensation, leading to increased power consumption. Therefore, the power consumption increases rather than decreasing heat rejection, refrigerant breakdown, or excessive superheat which stem from different factors.
