Fan Curves
The room fan coil is usually designed for free air delivery into a room but may be used
with minimal ducting having a static resistance of 0.25 inwc or less. The supply fan is
powered by an ECM operating in constant CFM mode. The delivered airflow remains
relatively constant over varying external static pressures
The supply fan also draws outside air through the HRV. The ratio of outside air and
return air is governed by the relative amounts of static pressure in the return air stream
and outside air stream. A dampered return air grille is supplied with each unit. Closing
this damper will create more return air static and result in more outside air.
