An AHU (Air Handling Unit) is a critical component of a hospital’s HVAC system. It is responsible for providing a comfortable and safe environment for patients and staff. AHUs are typically located in the mechanical room and are responsible for controlling the temperature, humidity, and air quality of the hospital. They are designed to filter, condition, and distribute air throughout the building. AHUs are also responsible for controlling the air pressure within the hospital, which helps to prevent the spread of airborne diseases.
