V - AP PLI CA TION
Energy Recovery Ventilators
(ERV)
are used with 15 to 20
ton rooftop units. These wheels conserve energy by mixing
warmer air with cooler air in the following manner:
Re cov ery Ven ti la tor Mode
The Recovery Ventilator 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 within the cassette frame work. In winter,
the wheel 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.
