They are usually located in the basement on the roof or on the floors of a building. The explanation for the high increase in energy efficiency within systems that have an ac drive resides in the affinity laws. Air handlers usually connect to a ductwork ventilation system that. Reducing speed by 20 can typically generate 20 30 savings in energy consumption within the air handling unit.

Package pool dehumidifying units. So the air flow provided by the air handlers will modulate based on what the need of the vav boxes require and what the duct static pressure sensor is reading. Rooftop packaged units 5. The pressure exiting the equipment is a discharge or positive pressure.

Package hygienic air handling units. The constant innovation in rooftop unit rtu design is driven by new demands for higher energy efficiency and local regulations. Some models use a centrifugal blower wheel on both ends of the motor. An air handler is usually a large metal box containing a blower heating or cooling elements filter racks or chambers sound attenuators and dampers.

Air handling fan motor most air conditioning units has one double shaft fan motor with a centrifugal blower wheel on one end for indoor conditioned air and a propeller fan to circulate outdoor air through the outdoor coil.
