Which constraint impacts a refrigerator's efficiency during its operational cycle?

💡 Explanation

Compressor back-pressure increases because excessive pressure requires more energy for compression; therefore the cycle becomes less efficient because the increased work demand reduces net cooling, rather than other throttling losses.
