Norridge Health Care Solves Ventilation
Puzzle with RenewAire
 After
being in operation for many years Norridge Health Care and Rehabilitation Center
in Norridge, Illinois had storage requirements that included 6 separate rooms
for various supplies and equipment. Local code requirements called for 3 air
changes per hour and 350 CFM per room. The rooms are located on opposite sides
of the building and on three separate floors. Needless to say the proper
ventilation of these rooms presented quite a puzzle for Cooling Equipment
Service of Elk Grove Village, Illinois.
Dave Apostal, Sales Manger for Cooling Equipment Service
looked at several options and consulted with their architect and Engineers from
RenewAire. The idea of straight exhaust and make up air was quickly ruled out
because of the expense required to bring in and heat the air to provide
comfortable ambient levels.
Cooling Equipment Service recommended the installation of
two
ERV450RT RenewAire Units. Each unit accommodates 3 storage rooms. Internal
ductwork was minimal, due to a straight run from roof to lower level rooms.
Exterior ductwork was slightly more complicated, due to fresh air intake
placement requirements set by local codes. A low limit cut out was added to
each unit that shuts down the unit when mixed return air falls below 60
degrees. According to Dave, this will occur only in the most frigid
conditions. The RenewAire units bring fresh air into the storage rooms through
an exchange core made of highly engineered resin plates. Through this core,
heat and moisture are transferred to the fresh air from the exhaust.
During the summer, cooler exhaust air flowing thru the
plate tempers fresh air. Likewise during the winter, colder outside air is
tempered by the warm air being exhausted thru the exchanger. “The unit
recaptures heat otherwise lost in exhaust air while controlling humidity
extremes. This greatly reduces the demand on heating equipment and lowers both
initial cost and energy bills”, says Dave.
"With the help of RenewAire we were able to include
operating savings in our proposal that provided a payback of only 3 years verse
going with a traditional exhaust and make-up air system. The most impressive
point of the RenewAire units was the solid cabinets and ease of installation.
Handles are sturdy, and allow access to all components of the system. We were
readily able to convince our customer that these units are built to last”.
