CalvinDoddMacCracken(1920-1999),anengineerandinventorfromNewJersey,iscreditedwithbuildingthe first “high velocity” style air handler, using smallinsulated ducts to deliver heated air at considerablepressureandhighvelocity.Thissystemquicklygainedinpopularity,andaspublic interestgrew,acompanycalled Space Conditioning Inc. incorporated theMacCracken Forced-Air House Heating Apparatus(Patent 2,488,548) into their product lines. This unitlater became known as the “Jet-Heet” System. Theprimarymarketforthesystemwasretrofitcoolingintohomes that had little room for duct work or in whicharchitecturalchangeswereundesirable.MacCracken’sairhandlerwasbasedontwoscientificprinciples:

Bernoulli’s Principle: (Daniel Bernoulli 1700-1782)Wherethereisdecreasedflow,youwillfindincreasedpressure.Wherethere is increasedflow,youwill finddecreasedpressure.

Venturi Effect: (Giovanni Battista Venturi 1746-1822)The increase in the velocity of a fluid stream as itpassesthroughaconstrictioninachannel.Calculatedby the Continuity Equation Q = VA where Q is thevolumetricflowrate,AistheareaofflowandVisthefluidvelocity.BecauseQdoesnotchange,asAgetssmallerthenVmustincrease.

Bernoulli’s PrincipleBernoulli’s Principle plays an important part in the

operationoftheHi-VelocitySystem.Toillustratehowthisworks, let’s lookat thedynamicsofashowerhead.Withthe showerhead in place, you create pressure in thepipingandmoveasmallamountofwaterquicklythroughthe showerhead holes, with the water being equallydistributedtoeachhole. Ifyouremovetheshowerhead,youremovethepressure,andbeginmovingalotofwaterslowlyandinonebigstream.Ittakesthesameamountofenergytomoveasmallamountofwaterquickly,asitdoestomovea largeamountofwaterslowly.Theamountofenergyyouhaveavailabledependsonyourwaterpressure.Thesmallholesintheshowerheadcreateapressurepointinyourwaterline,makingthewatermovingthroughthatpiperetainahighpressureandlowvelocity.Oncethewaterleavestheshowerhead,itisnolongerunderpressure,sothevelocityincreases.

ThisisverysimilartohowtheairflowworkswiththeHi-VelocitySystem.Ourfancoilpressurizestheductworkjustlikethewaterpipeofyourshower.Ourventoutletsactlike theholes in theshowerheadtoconvert thepressuretovelocity,anddelivertheconditionedairtoyourhome.Sinceairflowandwater flow follow thesameprinciples,youwillgetequalairflowfromalloftheHi-VelocitySystemventsinyourhome.Thisholdstruefromthefirstbranchduct to the lastone,and ismodifiedonlydue to frictionfromlongerlengthsofbranchducts.

The Science and History of Hi-Velocity Systems

With a conventional low velocity forced air-coolingsystem,therulethateveryoneknowsisavolumeof400CubicFeetofairperMinute (CFM) foreach ton.With400CFMatalowstaticpressure,andalargefacearea/thindepthcoil,theairiscooledandasmallamountofhumidityisremoved.WiththeHi-VelocitySystem,weusealowerCFMbuthigherstaticpressuretoaccomplishthesame amount of cooling, removingmore humidity fromtheairintheprocess.

400CFMisadesignruleforconventionalheatingsystemsandwillputanoptimumloadontheindoorcoil.This allows the coil to properly evaporate refrigerantandperformheat transfer.Sinceconventionalheatingsystems use a lower pressure than Hi-VelocitySystemsTM,ahigherairflowisneededtoprovideenoughmassofairtoperformtheheattransfer.Inversely,themore pressure that the air is under, the less CFM isneeded. How this works is on the microscopic level;the amount of airmolecules present through the coildetermineshowmuchheat transfer is done.Underahigherpressuretherearemoreairmoleculespresentpercubicfoot.TheHi-VelocitySystemrequireslessCFMofair topass through theevaporator,whilestillprovidingthesamecoilload.

Withasmuchcoilload(ifnotmore)passingthroughtheevaporator,equalorsuperiorcoolingwill result.Anadditionalbenefittomovingmoreairmoleculesthroughthecoilata lowerrate is the latentcooling. Sincetheair passing through the coil is in contact with the coilsurfaceareaforalongerperiodoftime,thetemperatureisdropped lower thanwithconventional systems, thusreducingtheair’sabilitytoholdmoisture.Ourcoilshavea unique design; they are highly efficient and typicallythicker than coils in conventional cooling systems.Withourstyleofcoolingcoilwewillremoveuptothirtypercentmoremoisturefromtheair.Thishasthebenefitof allowing a greater thermal comfort level, even at ahighertemperature.

Airvelocitycanbeeitherahelporahindrancetothermal comfort levels. While a small amount of airmovement isdesirableto increasetheskinevaporationrate, it has to be a uniformmovement over the entirebody in order to provide benefits to thermal comfortlevels.Anylargeamountsofdirectairvelocityoverapart of the human bodywill cause an uneven rate ofevaporationandheat transfer.This iswhytheventsfortheHi-VelocitySystemareusuallylocatedinlowtrafficareassuchascornersofaroom,ortothesidesofdoorsandwindows.Bylocatingtheventsintheseareas,theamountofdirectairmovementthathumanswillcomeincontactwithwillbeminimized,sincetheventshaveonlyaneight-inchconeofdirectinfluence.

Air temperature,humidity,anddirectair velocityarethe factors that will cause the most change to thermalcomfortlevels.Mostpeoplebelievethatcoldairisthekeyfactorforagoodairconditioningsystem.Consideringthatthehumanbodyhasanaturalcoolingsystembuiltin,thekeytocreatingacomfortableenvironmentforthehumanbody is tocreate therightcombinationofenvironmentalfactors.
