Question: 1 / 400

Which component is primarily responsible for removing humidity from indoor air?

The compressor

The evaporator coil

The evaporator coil is primarily responsible for removing humidity from indoor air because it acts as the cooling surface in the air conditioning system where the refrigerant absorbs heat. As warm, humid air passes over the evaporator coil, the temperature of the air drops. This cooling causes moisture in the air to condense on the coil surface, effectively removing humidity from the indoor environment. This process is similar to how dew forms on a cold glass; as the air cools, it loses its ability to hold moisture, which condenses and collects on the cooler surface. By managing the humidity levels within a space, the evaporator coil plays a vital role in enhancing comfort and ensuring a healthier indoor environment.
