Which risk increases substantially when heat input deviates from reversible isothermal stages in practical heat pump vapor-compression cycle?

💡 Explanation

Reduced cycle coefficient of performance rises substantially when real heat input is not isothermal because Second Law efficiency decreases. This is due to increased entropy generation. Therefore, performance suffers rather than improvements, because irreversibilities dominate under non-ideal compression.
