APPLICATIONS
APPLICATION CONSIDERATIONS
ModelACB/ACRBeltDriveBlowerCoilsofferawide
rangeofapplicationflexibility,whilemaintainingasim-
ple, easy to install unit design. These units are intended
to provide comfort cooling and heating within a small
footprint.Theymaybeappliedinmanytypesofbuilding
structuresincludingschools,officebuildings,hospitals,
condominiums, assisted living facilities, apartments or
stores.Applicationscanbeconstantorvariablevolume.
TherearemanyapplicationstheACB/ACRproductcan
beutilized.Someexamplesarelistedbelow.
Constant volume applications:
• Two-pipehydronicsystemforcoolingand/orheating
• Two-pipehydroniccoolingsystemwithelectricheat
• Four-pipesystemwithdedicatedheatingandcooling
coils
• Direct Expansion (DX) split systems with hydronic
heat
• DirectExpansion(DX)splitsystemswithelectricheat
Variable volume applications:
• Two-pipehydronicsystemforcoolingand/orheating.
• Two-pipehydroniccoolingsystemwithelectricheat.
• Four-pipesystemwithdedicatedheatingandcooling
coils.
ACOUSTICS
Controlofnoisewithinbothoccupiedandunoccupied
spaceshasbecomeincreasinglyimportanttodesigners
andbuilding owners/occupants.Properconsideration
mustbegiventoplacementofindoorairconditioning
units, particularly in the occupied space. Inherent
flexibilityofthefanandcoilcombinationinthevertical
configuration allows application in sound-sensitive
areas. In such instances, a fan running at a low speed
with a high capacity coil normally yields satisfactory
results.Italsomaybedesirabletoselectalargernom-
inal capacity unit and operate it at a less than nominal
airflowforfurtheracousticbenefit.
Threephasemotorsarerecommendedforsound-sen-
sitive applications to avoid potential single phase motor
hum. Unit operation in the stall region of the fan curve
is not recommended since it may cause unsatisfactory
noiselevelsandexcessiveunitvibration.
INSTALLATION
Thesefloormountedunitscanbeinstalledwithexternal
vibrationisolationonabaserail(ACR)oronareturn
plenum(ACB)atthecornerpoints.Thisrequiresflex
connectionsatthecornerbrackets,ductwork,electrical
connections and piping connections. One of the most
importantandbasicIAQissuesiscondensatemanage-
ment.Thefirststeptoensuretrouble-freeoperationis
properinstallation.Itisveryimportantthattheunitbe
mounted high enough so that the condensate drain
from the unit may be properly trapped. Please refer
to the ACB/ACR IOM Manual for specifics on this
issue. As with all HVAC systems, these units should
beinstalledaccordingtoallapplicableASHRAEstan-
dards,SMACNAandlocalcoderequirements.
OPERATING LIMITATIONS
Unitsmustnotbeoperatedabovemaximumfanspeed
or unit airflow as listed in the Fan Performance section
ofthiscatalog.Unitoperationatgreaterthanmaximum
fan speed could drastically reduce bearing life and
may result in a catastrophic wheel failure. Operating
atgreater thanthemaximumallowable airflowinthe
cooling mode may result in unsatisfactory operation
due to moisture carry over from the coil. In addition, it
isoftennoteconomicaltooperateaunitatitsmaximum
fanspeedduetothegreatermotorpowerrequirements.
Units with electric heat should not be operated with
leaving air temperature greater than 104°F (40°C),
to prevent excessive leaving air temperatures and
electricheatlimittrips.Ahydronic(orsteam)coiland
electricheatshouldnotbeoperatedsimultaneouslyto
prevent excessive leaving air temperatures and limit
trips.Electricheatunitsareequippedwithahighlimit
lockout switch that disables the electricheater if the
temperatureofthehydronic(orsteam)coilisgreater
than104°F(40°C).
Watercoilsmustnotbeoperatedaboveafluidvelocity
of8ft./sec.toreducethepossibilityofvelocityinduced
erosion and flow noise. Water coils must not be
operatedbelowafluidvelocityof1ft./sec.toprevent
degraded coil performance caused by laminar flow.
Thesehighorlowfluidflowratesmaynotbeincluded
