Product Manual B

Harbor View Windows, Heating and Air, Inc., Brookings, Oregon, has
installed ductless split system heating/cooling for years. Ductless sys-
tems offer high-energy savings, but can also have comfort challenges if
an air handler is not installed in each room. On a recent multi-family
project using ductless systems, Harbor View was able to overcome this
problem by installing an average of two AireShare transfer fans per
five-room townhouse to effectively distribute conditioned air to rooms
without air handlers.
“We thought it might be a great solution to a long term problem…to
flip a switch and be able to draw air conditioned or heated air out of
the main
rooms into
the small
rooms and
it’s working
perfectly,”
said Pat and
Sherry Nied,
Harbor
View’s
owners.

Model Selection Advice:
Since it is impractical to calculate heating and cooling loads for the variety of
geographic areas, construction methods and the temperature of transferred air
we base our model selection advice on providing a minimum of 3 Air
Changes/Hour (A CH) to the target room. Door under- cuts or pressure relief trans-
fer grilles in the target room are necessary for proper AireShare performance .

(AireShare CFM x 60) / (L x W x H of target room) = ACH
3-4 Air Changes/hour (ACH) recommended for best temperature equalization.
4-5 Air Changes/hour (ACH) recommended for rooms with high cooling or
heating loads.
Examples: Rooms with extensive outside walls, windows, over tuck under
garages or in extreme climates. More than one AireShare transfer fan can
be installed to reach desired number of air changes for large spaces.
