In an air conditioning system, moisture is removed from the air by what means?
AI Explanation
The correct answer is D) cooling coils.
In an air conditioning system, moisture is removed from the air by cooling coils. As warm, humid air passes over the cooling coils, the temperature of the air is lowered below its dew point, causing water vapor in the air to condense on the coils. This condensed water is then drained from the system, effectively removing moisture from the air.
The other options are incorrect because they do not directly remove moisture from the air. Separators and ducted traps are used for other purposes, while filters remove particulates but not moisture.
