История на развитието
Произход
Около 1700 г. пр. н. е. вавилонците са изобретили древна система за климатизация, която е използвала стълбове за вятър, монтирани на покрива. Естественият вятър от юфката преминава през студената вода и духа в стаята, карайки хората на закрито да се чувстват прохладни.
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.

Оценка на ефективността
EER (EnergyEfficiencyRatio), коефициентът на енергийна ефективност, т.е. капацитетът на охлаждане, разделен на час. Следователно, колкото по-висока е стойността на EER на климатика, толкова повече енергия обикновено се пести.
COP (Коефициент на ефективност), коефициентът на ефективност, т.е. топлината, консумирана от климатика за единица време, разделена на консумираната мощност.

Коефициентът на енергийна ефективност е съотношението на преработения капацитет на охлаждане към работната мощност, колкото по-голямо, толкова по-добро. Коефициентът на енергийна ефективност на климатика с фиксирана скорост 3,2-3,6 (охлаждащ капацитетCC<4500W) е разделен на три нива, като първото ниво е най-добро, т.е. съотношението на енергийна ефективност по-горе3 .6 е най-енергийно ефективен продукт за климатизация от първо ниво (Старият стандарт е разделен на пет степени, новият стандартен климатик с фиксирана скорост е разделен на три степени, а инверторният климатик е разделен на пет степени 3.0-5.2.

Преценка на неуспеха
Често срещани явления на неуспеха
Мръсно запушване и запушване с лед на хладилната система;въздушното филтриранеУстройството е блокирано;въздухът и изходът са блокирани от препятствия и др.
Намотките на мотора, намотките на двигателя на вентилатора, бобините на електромагнитния клапан, бобините на релетата и контактите бяха изгорени.
Вентилаторът заседна, лагерът на движещата се част заседна и т.н.
Метод за преценка на грешка
Основният метод за преценка на често срещаните неизправности на домашните климатици е: гледайте, слушайте, докосвайте, измервайте и анализирайте.
1.Вижте: Внимателно наблюдавайте работните условия на всеки компонент от климатика, като се фокусирате върху трите части на тази хладилна система, електрическа система и вятърна система, за да определите дали работят правилно.

2.Слушайте: Включете захранването и слушайте внимателно, за да видите дали компресорът на климатика работи нормално, дали има необичаен шум, дали вентилаторът работи шумно, дали шумът е много силен и т.н. По време на работа на климатика, при нормални обстоятелства, вибрациите са леки и шумът като цяло под 50DB. Ако вибрациите и шумът са твърде силни, възможните причини са:
Пластмасовите възглавници от пяна и др. могат да накарат климатика да вибрира и да шуми повече по време на работа. Особено когато току-що е стартиран и спрял.
Ако шасито се сблъска, оста на вентилатора ще се премести и лопатките ще излязат от равновесие. Ще се чуе и звук от трясък; ако във вентилатора има чужд предмет, лопатките също ще издават звук от трясък, когато се докоснат..
3.Докоснете: Докоснете съответните части на климатика, за да усетите топлината, студа и треперенето и т.н., което е полезно за преценка на естеството и местоположението на повредата. При нормални обстоятелства температурата на кондензатора постепенно намалява отгоре надолу, а температурата на долната част е малко по-висока от температурата на въздуха Ако целият кондензатор не е топло в горната част, орално, въпреки че е горещо, но има значителна разлика в температурата между горната и долната съседни тръби, това е ненормално. Изпарителят ще се почувства студен и лепкав, ако поставите пръст, потопен във вода, върху повърхността на изпарителя при нормални условия. трябва да има топло усещане при нормални условия (малко по-висока от температурата на околната среда ,и по принцип същата температура на тръбата в края на кондензатора). И т.н. не са нормални. Температурата на смукателната тръба на 200 mm от компресора трябва да е подобна на температурата на околната среда при нормални условия.
