Which of the following statements is true regarding evaporator coils?

Evaporator coils play a crucial role in the refrigeration and air conditioning cycle. Their primary function is to absorb heat from the environment inside a conditioned space, which cools the air by converting the refrigerant from a liquid to a gas. As the refrigerant evaporates, it absorbs moisture from the air, thus not only cooling the space but also dehumidifying it. This dual role is essential for maintaining comfortable indoor conditions, especially in humid climates where excess moisture can lead to discomfort and potential mold growth.

The statement regarding the use of evaporator coils emphasizes that they are versatile components designed to perform both cooling and dehumidification effectively. This characteristic is particularly important in air conditioning applications, where maintaining low temperatures and proper humidity levels is critical for occupant comfort and equipment efficiency.

By contrast, the other options do not accurately describe the capabilities or configurations of evaporator coils. They are not limited to split configurations, as they can also be found in packaged or window units. Additionally, evaporator coils are not primarily for heating; that function is typically addressed by other components such as heat exchangers or separate heating systems. Lastly, they do not only operate in low humidity conditions; in fact, they are particularly effective in high humidity environments, where their ability
