Climate Wizard CW-H10 - Commissioning; Setting the Discharge Damper

Settingthe AirDischargeDamper
AIRFLOWBALANCING
THISPROPORTIONISCRITICAL TO ACHIEVINGSATISFACTORY PERFORMANCE.
InorderfortheClimateWizardtoproducecoolairitismandatorythatsomeoftheinletairisforcedtoreturnthroughthe
heatexchangerandbeexhaustedtoatmosphere. Thereforeonlyaproportionofthetotalinletairisdeliveredintothe
cooledzone;it'sabout50/50.
Thesupplyairtransitionisequippedwithasetofdampersthatcanbeadjustedto'balance'theproportionofsupplyand
exhaustairstreams. Thedamperisfactoryset,butmayneedtobere-adjustedduringCommissioningdependingonthe
resistanceoftheductsystem.
Underneaththesupplyairtransitionisamanualquadrantdamperleverwithlockingscrew(seephotobelow). Thereis
alsoaholeintherighthandsideofthesupplyairtransitionsuitableformanometertubesformeasuringpressure(see
diagrambelow). Pressuremeasuringshouldbecarriedoutusinganaccurateinstrument,eitherelectronicor
“inclinedtubemanometer”.
a. ConnectallexternalductworktotheClimateWizardinpreparationforbalancingthesystem.
b. Openfullyallsupplyairoutletsintheentireductworksystem.
c. StarttheClimateWizardinMANUAL andVENT modesonfullspeed.
d. AdjusttheClimateWizarddamperuntilthepressureinthetransitionstabilisesasfollows:
CW-H10 240Pa
CW-H15 215Pa
e. Proceedtobalancetheexternalductandoutletsinyourusualmanner.
f. Checkandifnecessaryre-adjusttheClimateWizarddamperbacktotheabovevalues.
g. Lockthedamperinitsfinalposition

ClimateWizardCooling Applications
ClimateWizardisdesignedtobeusedin3differenttypesofapplications:
- in cases where the Climate Wizard is the primary source ofAir Conditioning for the building.
- in cases where the Climate Wizard is used to augment the capacity of the existing air
conditioning system, or to extend its reach into the building, or to greatly reduce the energy consumption of the Air
Conditioning plant.
- in cases where the Climate Wizard is used to pre-cool the fresh air supply to new or existing
refrigerated air conditioning plants in order to prolong the life of the plants, to save significant energy, and to greatly reduce
demand on existing infrastructure which becomes over-stressed in heat-wave conditions.
Ineachapplicationtype,remarkableenergysavingscanbeachievedcomparedwithconventionalRefrigerated Air
Conditioning.
