Which process determines heat pump effectiveness during defrost cycle?

💡 Explanation

Refrigerant migration and stratification in the evaporator results in reduced heat transfer because liquid pools, thus decreasing evaporating surface area leading to lower delta T; therefore capacity drops, rather than limitations caused solely by conduction.
