Which mechanism causes ice accumulation on air conditioner evaporators?

💡 Explanation

Ice accumulates due to the latent heat of fusion during phase change, because moisture in the air freezes when evaporator temperature drops below 0°C. Therefore ice forms, rather than the water merely cooling without changing phase.
