In an air-source heat pump, which outcome occurs when increasing evaporator frosting during winter?

💡 Explanation

Icing on the evaporator coil induces lower surface heat transfer because it introduces additional thermal resistance through the **thermal conduction** mechanism, therefore reduces heat absorption, rather than aiding heat transfer; other options concern fluid states.
