Historie vývoje
Původ
Kolem roku 1700 př. n. l. vynalezli Babyloňané starodávný klimatizační systém, který využíval větrné sloupy nainstalované na střeše.
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.

Popularization
Butwhenitcomestoair-conditioningcanbepopularized,mainlythroughcinemas.MostAmericansareexposedtoairconditionersforthefirsttimeinmovietheaters.Cinemasinthe1920susedair-conditioningtechnologytopromisetoprovidecoolairtotheaudience,makingair-conditioningasattractiveasthemovieitself,andsummerreplacedwinterasthepeakseasonforwatchingmovies.Subsequently,alargenumberofindoorentertainmentvenuesopenthroughouttheyear,suchascasinos,indoorsportsfieldsandshoppingmalls,wereattributedtotheadventofair-conditioning.

Posouzení selhání
Běžný jev selhání
Znečištěné a ledové ucpání chladicího systému;filtrace vzduchuZařízení je zablokováno;přívod a výstup vzduchu je zablokovaný překážkami atd.
Došlo ke spálení vinutí motoru, vinutí motoru ventilátoru, elektromagnetických ventilových cívek, reléových cívek a kontaktů.
Zaseknutý ventilátor, zaseknuté ložisko pohybující se části atd.
Metoda posouzení chyby
Základní metoda posuzování běžných chyb domácích klimatizací je: dívat se, poslouchat, dotýkat se, měřit a analyzovat.
1.Podívejte se: Pečlivě dodržujte pracovní podmínky každé součásti klimatizace, zaměřte se na tři části chladicího systému, elektrický systém a větrný systém, abyste zjistili, zda pracují správně.
Refrigeratingmachineoil,youcanalsouseacleansoftclothorsoftpapertowipethepipeweldingandjointconnections,andobservewhetherthereisanyoilstainstodeterminewhetherthereisleakage.
2.Poslouchejte: Zapněte napájení a pozorně poslouchejte, abyste viděli, zda kompresor klimatizace běží normálně, zda je nějaký abnormální hluk, zda je ventilátor hlučný, pokud je hluk příliš silný atd. vibrace a hluk jsou hlasité, možné důvody jsou:
Pěnové plastové podušky atd. mohou způsobit, že klimatizační jednotka bude více vibrovat a bude hlučnější. Zejména když je právě spuštěna a zastavena.
Pokud se podvozek srazí, osa ventilátoru se pohne a lopatky budou nevyvážené. Ozve se také nárazový zvuk; pokud je ve ventilátoru cizí předmět, budou lopatky při dotyku také vydávat nárazové zvuky.
3.Dotkněte se:Dotkněte se příslušné části klimatizačního zařízení, abyste cítili teplo, chlad, třes atd., což pomáhá posoudit povahu a umístění chyby. Za normálních okolností se teplota kondenzátoru postupně snižuje, teplota od nejvyšší k nejnižší teplotě se postupně snižuje. .Jestliže celý kondenzát není horký pro horní část je mírně teplý, orální, ačkoli je zastřelen, ale mezi horním a spodním sousedním potrubím je významný rozdíl v teplotě, je abnormální. za normálních podmínek (o něco vyšší než je okolní teplota ,a v podstatě stejná je teplota potrubí na konci kondenzátoru). Atd. nejsou normální. Teplota sacího potrubí 200 mm od kompresorů by měla být podobná teplotě okolí za normálních podmínek.
4.Measurement:Inordertoaccuratelydeterminethenatureandlocationofthefault,itisoftennecessarytouseinstrumentsandmeterstocheckandmeasuretheperformanceparametersandstatusoftheairconditioner.Forexample,usealeakdetectortocheckforrefrigerantleakage;useamultimetertomeasurewhetherthepowersupplyvoltage,thegroundcurrentofeachterminalandtheoperatingcurrentmeettherequirements,andtheairconditionercontrolledbythecomputershouldalsomeasurewhetherthepotentialofeachcontrolpointisnormal.
