Ahu Humidity Control is the process of controlling the humidity level to a desired value in air handling units (AHUs). It ensures that the humidity levels inside an AHU remain at a healthy and comfortable level, while preventing them from exceeding safe limits to avoid condensation or other related issues. This process requires skilled technicians to monitor and adjust relative humidity levels through manual methods or automated systems. By keeping these levels regulated, AHUs can provide improved indoor air quality, reduce the risk of mold growth, and create a more comfortable environment for occupants.
