V - Ap pli ca tion
Energy Recovery Ventilators (
ERV)
are used with units
equipped
with a return damper assembly.
These wheels
conserve energy by mixing warmer air with cooler air in the
following manner:
Re cov ery Mode
The Recovery Mode is accomplished by two blowers
providing continuous exhaust of stale indoor air and
replacement by equal amount of outdoor air. Energy
recovery is achieved by slowly rotating the Energy

Recovery Wheel (ERW) within the cassette frame work. In
winter, the ERW adsorbs heat and moisture from the
exhaust air stream during one half of a complete rotation
and gives them back to the cold, drier intake air supply
during the other half rotation. In summer, the process is
automatically reversed. Heat and moisture are absorbed
from incoming fresh air supply and transferred to the
exhaust air stream. This process allows outdoor air
ventilation rates to be increased by factors of three or more
without additional energy penalty or increase in size of
heating or air conditioning systems.
