Which consequence results when a heat pump operates with reversed Stirling cycle?

💡 Explanation

Reduced temperature differential worsens performance, because heat transfer needs adiabatic processes, reducing efficiency. Approaching ambient temperature, the Stirling cycle suffers isothermal degeneration, therefore the heat pump struggles, rather than violating Carnot limits or transitioning refrigerant.
