REDUCE YOUR BUILDING'S VENTILATION COST BY UP TO 85% OVER STANDARD ROOFTOP UNITS. ASHRAE 62 specifies ventilation rate for different types of commercial buildings. In each commercial building, there

is a ventilation requirement for occupancy, building size and building type. Furthermore, per ASHRAE 62 and other

building codes, ventilation is required when the building is occupied. Depending on occupancy, building size and building type, ventilation requirements during occupied mode generally vary from 10% to 40% of the package unit

airflow. Supply fans in standard package units use constant volume, which means they have a single high speed airflow. They supply this ventilation (fresh air) at maximum airflow 2000 Indoor Fan Power (Watts)

resulting in maximum energy usage. A Ruud Package Unit with VFD Technology, operates the supply fan at two speeds opposed to one. During the fan only mode and 1st stage cooling demand it operates at 50% of high speed. During 2nd stage cooling and heating demand it operates at 100%.

The Science Behind VFD Technology

500

The Fan Laws simply state power goes down eight times faster than airflow. Low speed watts = high speed watts
