Kehityshistoria
Alkuperä
Noin 1700 eaa.Babylonialaiset keksivät muinaisen ilmastointijärjestelmän, joka oli tuulipylväitä asennettuna katolle.Nuudelta peräisin oleva luonnollinen tuuli kulkee kylmän veden läpi ja tuulettimet huoneeseen.
Inthe19thcentury,theBritishscientistandinventorMichaelFaraday(MichaelFaraday)discoveredthatcompressingandliquefyingacertaingascanfreezetheair.Thisphenomenonoccurswhentheliquefiedammoniagasevaporates.Stayattheorizing.
In1842,FloridadoctorJohnGorriebuiltanewbuildingwithcentralairconditioning.AnengineerfromHoboken,NewJersey,AlfredWolff,assistedinthedesignofthisnewairconditioningsystemandmovedthetechnologyfromthetextilefactorytothecommercialbuilding.Heisconsideredoneofthepioneersinmakingtheworkingenvironmentcooler.
Inthelate1902,thefirstmodern,electric-poweredairconditioningsystemwasinventedbyWillisCarrier(1876-1950).ThedifferencebetweenitsdesignandWolff'sdesignisnotonlytocontrolthetemperature,butalsotocontrolthehumidityoftheairtoimprovethequalityoftheproductionprocessataprintingfactoryinBucklin,NewYork.Thistechnologyprovidesalowheatandhumidityenvironmenttomakethepaperareaandinkarrangementmoreaccurate.Later,Carrier'stechnologybegantobeusedintheworkplacetoimproveproductionefficiency.CarrierEngineeringCompanywasalsoestablishedin1915tocopewiththesurgeindemand.Underthegradualdevelopment,airconditioningbegantobeusedtoimprovethecomfortinhomesandcars.Salesofresidentialair-conditioningsystemsdidnotreallytakeoffuntilthe1950s.Builtin1906,theRoyalVictoriaHospitalinBelfast,NorthernIreland,isofspecialsignificanceinarchitecturalengineeringandisknownastheworld'sfirstair-conditionedbuilding.
In1906,StuartW.CramerofCharlotte,NorthCarolina,USAwaslookingforwaystoincreasetheairhumidityinhissoutherntextilemill.Cramernamedthetechnologyairconditioninganduseditinapatentapplicationinthesameyearasasubstituteforwaterconditioning.Waterconditioningwasawell-knownprocedureatthetime,whichmadetheproductionoftextileseasier.Hecombinedwatervaporandventilationsystemsto"regulate"andtransformtheairinthefactory,andcontroltheairhumidity,whichisveryimportantinthetextilefactory.WillisCarrierusedthisnameandputitinthenameofthecompanyhefoundedin1907:"GaliaAirConditioningCompany"(nowCarrierCompany).
In1915,Carrierestablishedacompany,whichisoneoftheworld'slargestair-conditioningcompanies.But20yearsaftertheinventionoftheairconditioner,machineshavealwaysbeenenjoyed,notpeople.Until1924,amallinDetroitoftenfaintedduetotheswelteringweather,andfirstinstalledthreecentralairconditioners.Thiswasagreatsuccess.Thecoolenvironmentmadepeople'sdesireforconsumptiongreatlyincreased.Sincethen,airconditioningAsapowerfultoolforbusinessestoattractcustomers,theeraofairconditionersservingpeoplehasofficiallyarrived.

2.Kuuntele:Kytke virtaa ja kuuntele huolellisesti nähdäksesi, toimiikoilmastointilaitteenkompressori normaalisti,jos on epänormaalia melua,jostuuletin käy äänekkäästi,josmelu on kovaa jne.Ilmastointilaitteen toiminnan aikana,ilmastointilaite ei ole päällä, alle 50 DB. Jos tärinä ja melu ovat liian voimakkaita, mahdollisia syitä ovat:
Vahtomuovityynyt jne. voivat saada ilmastointilaitteen tärisemään ja meluisampaan toimintaan. Varsinkin kun se on juuri alkanut ja pysähtynyt.
Jos runko törmää, tuulettimen akseli liikkuu ja siivet ovat epätasapainossa. Seinästä kuuluu myös törmäävää ääntä; jos tuulettimessa on jokin muu esine, siivet kuulevat myös törmäävän äänen, kun he koskettavat.
3.Kosketus: Kosketa asianmukaista ilmastointilaitteen osaa tunteaksesi lämmön, kylmän ja vapinaa jne., mikä auttaa arvioimaan vian tyypin ja sijainnin. ylemmän ja alemman vierekkäisten putkien välillä on huomattava lämpötilaero, joskoko lauhdutin ei olekuumeayläosa on hieman lämmin. kuivausrummun ja ulostulon tulisi olla lämmin tunne normaaleissa olosuhteissa (hieman korkeampi kuin ympäristön lämpötila ,ja periaatteessa sama kuin lauhduttimen päässä olevan putken lämpötila).Jne.eivät ole normaaleja.Imuputken lämpötilan 200 mm:n päässä kompressoreista pitäisi olla samanlainen kuin ympäristön lämpötila normaaleissa olosuhteissa.
