Energy Core Ventilator
Unit Overview
Summer Operation
Outdoor air is preconditioned (temperature and moisture
levels are decreased) by the transfer of energy from the
cooler, drier return air through the energy recovery core.
The preconditioned air is typically mixed with return air
going back to the air handler for final conditioning.
Winter Operation
Outdoor air is preconditioned (temperature and moisture
levels are increased) by the transfer of energy from
the warmer, more humid return air through the energy
recovery core. The preconditioned air is typically
mixed with return air going back to the air handler for
finalconditioning.
