← ScienceWhich outcome occurs when latent heat increases greatly during phase transitions in a refrigeration cycle with a fixed-capacity evaporator?
A)Compressor overheating risk increases sharply✓
B)Increased subcooling at the condenser outlet
C)Evaporator superheat decreases significantly
D)Refrigeration capacity reaches highest efficiency
💡 Explanation
Compressor overheating increases because latent heat increase demands higher mass flow for cooling, leveraging the latent heat of vaporization; this increases volumetric compression ratios that cause overheating, therefore compressors are driven out of the design window, rather than enabling optimized capacities.
