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

Variable volume applications:

• 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
