What function does the evaporator coil provide?

  1. Heat

  2. Dehumidification

  3. Humidification

  4. Reheat

The correct answer is: Dehumidification

The evaporator coil plays a crucial role in an air conditioning system, and its primary function is dehumidification. As warm air from the room passes over the cold evaporator coil, moisture from the air condenses on the coil, effectively removing humidity from the indoor environment. This process not only cools the air but also lowers the humidity levels, making the space more comfortable. When the air is cooled and moisture is removed, it helps to prevent excessive dampness, which can lead to mold growth, musty odors, and discomfort. Therefore, the evaporator coil is essential for maintaining an optimal indoor climate by ensuring that humidity levels are kept in check, contributing to overall air quality and comfort in the space being conditioned.
