Factor that affect air handling unit?

Several factors affect the performance of an air handling unit (AHU), including airflow rates, temperature and humidity levels, and the type and condition of filters used. Proper insulation and ductwork design also play critical roles in efficiency and system effectiveness. Additionally, the maintenance and cleanliness of the unit significantly influence its operational efficiency and lifespan. Lastly, external environmental conditions, such as outdoor air quality and temperature, can impact the AHU's performance and energy consumption.
