Which system is responsible for regulating temperature and humidity in a space?

The air-conditioning system is specifically designed to regulate both temperature and humidity in a space effectively. It works by cooling the air during warmer months and can also dehumidify the air, making it more comfortable in humid conditions. The air-conditioning system typically uses a refrigeration cycle to remove heat from the indoor air, which not only lowers the temperature but also helps in controlling moisture levels.

In contrast, while heating systems are effective at raising temperatures, they do not regulate humidity levels. Similarly, cooling systems primarily focus on reducing temperature without inherently addressing humidity control. Ventilation systems improve air quality by exchanging indoor air with outdoor air but do not specifically manage temperature or humidity on their own. Thus, the unique combination of temperature and humidity control is what makes the air-conditioning system the correct choice.
