1. Kupisa: tembiricha chiyero chekuti kupisa kana kutonhora chinhu chii.
Kune matatu anowanzo shandiswa tembiricha (tembiricha zviyero): Celsius, Fahrenhiit, uye tembiricha yakakwana.
Celsius tembiricha (t, ℃): tembiricha yatinowanzo shandisa. Tembiricha yakayerwa ne celsius thermometer.
Fahrenheit (f, ℉): tembiricha inowanzo kushandiswa muEurope uye nyika dzekuAmerica.
Tembiricha Shanduko:
F (° F) = 9/5 *** t (° C) +32 (tsvaga tembiricha muFahrenheit kubva kuCelsiuses)
t (° C) = [F (° F) -32] * 5/9 (tsvaga tembiricha muCelsius kubva kuCelsius kubva kuFahrenust Tembiricha)
Chiyero che tembiricha tembiricha (t, îk): kazhinji inoshandiswa mukuverenga kwavo kuverenga.
Tembrees tembiricha uye celsius tembiricha shanduko:
T (ºk) = t (° C) +273 (tsvaga tembiricha yakakwana kubva kuCelsius muCelsius)
2.
Zvikamu zvakajairika zvekumanikidzwa ndezvekuti:
MPA (Megapascal);
Kpa (kpa);
bar (bar);
Kgf / CM2 (Square Centimeter Kilogram Simba);
ATM (yakajairwa kumanikidzwa);
MMHG (millimeter yeMercury).
Kushandurwa kwehukama:
1mpa = 10bar = 1000kpa = 5500.6 mmhg = 10.197 kgf / cm2
1TM = 760mmhg = 1.01326bar = 0.101326mpa
Kazhinji inoshandiswa muinjiniya:
1bar = 0.1mpa ≈1 kgf / cm2 ≈ 1atm = 760 mmhg
Dzinoverengeka Dzvinyiriro:
Dzvinyiriro yemhando (PJ): Mumudziyo, kumanikidzwa kunoitwa mumadziro emukati wemudziyo neyekupedzisira kufamba kwemamorekuru. Dzvinyiriro muFrigentrant Thermodynamic Properties tafura inowanzo kumanikidzwa.
Gauge Dzvinyiridzo (PB): Dzvinyiriro yakayerwa neyekudzvinyirira geji mufiriji system. GAUGE yekumanikidza kusiyana kwacho pakati pekumanikidza kwegesi mumudziyo uye kumanikidzwa kwemweya. Izvo zvinowanzoda kuti gadziriso yekumanikidza pamwe ne 1bar, kana 0.1mpa, ndiko kudzvinyirira zvachose.
Vacuum degree (h): Pakadzvinyirirwa nejira, tora kukosha kwayo uye uzviratidze mumuganho.
3. Refigerant Thermodynamic Properties Tafura: Iyo Firigener Thermodynamic Properties tafura inoratidzira tembiricha (tembiricha tembiricha) uye kumanikidzwa (kugadziriswa (kugadziriswa (madhiri eiyo firiji iri munzvimbo yakazara. Iko kune imwe-kune imwe chete yekunyorerana pakati pekushisa nekumanikidzwa kweiyo firiji iri yakazara.
Izvo zvinowanzoda kuti firiji iri mueveve, condenser, gasi-yemvura inoparadzanisa, uye yakaderera-kudzvanywa kutenderera mugomba rakazara. Iyo vapor (mvura) mune yakawiswa nyika inonzi yakadanidzirwa vapor
Mugadziriro yefirisitia, yefiriji, kudzvinyirira kwekutenderera uye kudzvinyirira uye kudzvanywa kweguta kuri mune imwe-kune imwe tsamba. Iyo yepamusoro tembiricha yekudziya, yakakwira kudzvanywa kudzvanywa.
Kuvharira kwefiriji muVapambi uye kumisikidzwa muCondener kunoitwa munzvimbo yakazara Ukama hunoenderana hunogona kuwanikwa mumatafura yefriggerder thermodynamic zvivakwa.
4. Firiji tembiricha uye kudzvinyirira tafura yekuenzanisa:
5.. Pasi peimwe kumanikidzwa, tembiricha yemvura yakaderera pane kudzikiswa kupisa pasi pekumanikidza kunoenderana, iyo inonzi yakasarudzika mvura.
Iko kukosha uko kusimba kwekupembera kunodarika tembiricha yekuisa tembiricha inonzi superheat. Iyo Suction Superheat Degree inowanzodikanwa kuti ishandiswe pa5 kusvika ku10 ° C.
Iko kukosha kweiyo tembiricha yemvura yakaderera pane iyo tembiricha tembiricha inodaidzwa kuti mvura subcooling degree. Liquid Subcooling inowanzoitika pazasi peiyo Condenser, mune yehupfumi, uye mune intercooler. Iyo yemvura inogadzirisa pamberi pebumbiro risati raunobatsira kuvandudza kunaka kwekutonhora.
6. Kubuda, Kubata, Kupera, Kumanikidzwa Kwekudzvinyirira uye Tembiricha
Kudzvinyirira kunopinda (tembiricha): kudzvinyirira (kupisa) kweiyo firigent mukati meiyo evaporator. Kudzvinyirira kudzvinyirira (tembiricha): kudzvinyirira (kupisa) kweiyo firiji mune condenser.
Suction Dzvinyiriro (Tembiricha): Kumanikidza (tembiricha) kuchiteshi chechikepe che compressor. Discharge kudzvinyirira (tembiricha): kudzvinyirira (tembiricha) ku compressor discharge chiteshi.
7. Tembiricha yekupisa Iyo tembiricha mutsauko ndiyo yekufambisa simba rekupisa
Semuenzaniso, pane musiyano wekupisa pakati pefiriji uye inotonhorera mvura; firiji uye brine; firiji uye yekuchengetedza mweya. Nekuda kwekuvapo kwekushisa kwekushisa tembiricha tembiricha, tembiricha yechinhu chinofanira kutonhorera chakakwira kupfuura kupisa kwemuchura; tembiricha yekudzikisira yakakwira kupfuura tembiricha yeiyo inotonhorera yepakati ye condenser.
8. Humidity: kunyorovesa kunoreva kuseka kwemhepo. Humidity ndicho chinhu chinobata chinjana kupisa.
Pane nzira nhatu dzekuratidza humidity:
Akanyorovesa Humidity (Z): Iyo huwandu hwemvura yemvura pamukombe wemvura yemhepo.
Zvinyorwa zvekunyorova (d): huwandu hwemvura yemvura yaive mune imwe kilogiramu yemhepo yakaoma (G).
Humidive humidity (φ): inoratidza iyo degree kune iyo chaiyo mhedziso yakanyorova yemhepo iri pedyo neyakagadziriswa zvachose humidiity.
Pane imwe tembiricha, imwe huwandu hwemhepo inogona kungobata imwe huwandu hwemvura yemvura. Kana iyi muganho ikapfuura, iyo yakawandisa mvura yemvura inokanda kuita fog. Uku kumwe kushoma kwehuwandu hwemvura yemvura inonzi yakadanwa humidity. Underurongets humidity, pane inoenderana yakawandisa yakanyoroveswa zb, inoshanduka neye tembiricha yemhepo.
Pane imwe tembiricha, apo mweya wekushomeka uchisvika kune humiziro hwakazara, inonzi mhepo yakazara, uye haigone kubvuma kuwedzera kwemvura. Mhepo iyo inogona kuramba ichibvuma imwe huwandu hwemvura yemvura inonzi isina kusimbiswa mweya.
Humidive humidity ndiyo huwandu hwemhedziso hwakanyorovesa z hweMhepo isina kusimbiswa kumhedziso yeZB yemweya wakazara. φ = Z / ZB × 100%. Shandisa iyo kuratidza kuti ndeyekuvhara kwakakwana kwakanyoroveswa kwakanyoroveswa kune iyo yakazara yakanyorovesa humidiity.
