Mamwe Marudzi Akasiyana Emafiriji
Refrigerant R600A
Iyo R600a itsva hydrocarbon refrigerant ine kuita kwakanaka. Inotorwa kubva muzvigadzirwa zvepanyama, izvo zvisingakuvadzi ozone layer, hazvina greenhouse effect, uye zvakasvibirira uye zvakatipoteredza.
Iyo ine yakakwira yakadzika kupisa kwe evaporation uye yakasimba kutonhora kugona: kunaka kuyerera kwekuita, kuderera kutapurirana Kudzvinyirira, kuderera kwesimba rekushandisa, uye kunonoka kupora kwekushisa kwemutoro. Inoenderana neakasiyana compressor lubricant, iri imwe nzira kune R12.R600a igasi rinopfuta.
Refrigerant R404A
R404A inonyanya kushandiswa kutsiva R22 uye R502. Iyo inoratidzirwa nehutsanana, yakaderera chepfu, isiri-mvura, uye yakanaka firiji mhedzisiro. R404A refrigerant haina mhedzisiro yakaoma pane ozone layer
Iyo R404A inoumbwa neHFC125, HFC-134a, uye HFC-143. Igasi risina ruvara patembiricha yekamuri uye mvura isina ruvara inoonekera pakumanikidza kwayo.
Inokodzera midziyo mitsva yekutengesa firiji, kutakura midziyo yefiriji, uye midziyo yefiriji pane yepakati uye yakaderera tembiricha.
Refrigerant R407C
Refrigerant R407C musanganiswa wemahydrofluorocarbons. Iyo R407C inonyanya kushandiswa kutsiva iyo R22. Iyo yakachena, yakaderera muchetura, isingabatike, uye ine zviratidzo zveyakanaka firiji maitiro.
Pasi pemhepo inofefetera, vhoriyamu yayo yekutonhodza huwandu uye firiji coefficient isingasviki 5% yeR22. Kutonhodza kwayo coefficient haichinji zvakanyanya pakudziya kwakadzika, asi kutonhora kwayo pavhoriyamu yevhoriyamu i20% zvishoma.
Refrigerant R717 ( Ammonia)
R717 (ammonia) ndeye refrigerant-giredhi ammonia inoshandiswa mune yakaderera kusvika yepakati-tembiricha firiji. Haina ruvara uye ine chepfu zvakanyanya. Asi iyo firiji inoshanda zvakanyanya ine zero global warming inokwanisa.
Zviri nyore kuwana, ine mutengo wakaderera, yepakati kudzvanywa, hombe unit kutonhora, yakakwira exothermic coefficient, inenge isinganyunguriki mumafuta, kuyerera kudiki kusinga. Asi kunhuwa kunotsamwisa uye kune chepfu, kunogona kupisa uye kuputika.
Kuenzanisa Kwemafiriji
Zvinodiwa Zvivakwa ZveFiriji Yakanaka:
Chinhu chefiriji chinoonekwa sechinhu chakanaka chefiriji chete kana chine zvinhu zvinotevera:
1. Low Boiling Point
Nzvimbo yekubikira yefiriji yakanaka inofanira kunge yakadzikira pane tembiricha iyoyo pakumanikidzwa kwakajairika setembiricha inodiwa kuchengetedza kutonhora, tangi yehuropi, kana imwe nzvimbo inotonhora. Ndiko, apo firiji inoputika.
Kudzvinyirirwa mumakoiri efiriji kunofanira kunge kwakakwirira kudarika kumanikidzika kwemhepo kuitira kuti kubuda kwefriji kubva kumakoiri kunogona kuongororwa nyore nyore.
2. Latent Heat Of vaporization
Iyo yakadzikama kupisa (huwandu hwekupisa hunodiwa kuti uchinje kubva kumvura kuenda kune gasi pane imwe tembiricha) kune evaporator yemvura yefiriji inofanira kunge yakakwira.
Zvinwiwa zvine kupisa kwakawanda pakg pakg zvinosiya firiji yakakura nekushandisa kupisa kwakawanda pane mvura ine kupisa kushoma.
3. Low Specific Volume
Huwandu hwehukama hwefiriji gasi hunofanirwa kuve hushoma kuitira kuti gasi rakawanda rizadzwe muCompressor panguva. Saizi yemuchina wefiriji inotarwa zvichienderana nekupisa kwakadzikama uye huwandu hwehuwandu hwefiriji.
4. Liquify At Lower Pressure
Firiji yakanaka inoshanduka kuita mvura ine simba shoma chete nekuitonhodza nemvura kana mhepo. Ichi chivakwa chinowanikwa muammonia (NH3).
Cherechedza:
Zvimwe zvezvinyorwa zvakatorwa kubva paInternet. Kana pane kukanganisa, tapota taura nesu kuti tibvise. Kana iwe uchifarira mukupisa pombi zvigadzirwa, ndapota inzwa wakasununguka kubata OSB kupisa pombi kambani, isu tiri sarudzo yako yakanaka.
