Masisitimu eFiriji anoshandisa mafiri sekushanda kwemvura, uye zviwi zvinowanzove nemafomu maviri: mvura uye gasi. Nhasi isu tichataura nezve ruzivo rwakakodzera nezvemvura inofona.
1. Ndiyo firiji yemvura kana gasi?
Mafuta anogona kukamurwa kuita zvikamu zvitatu: Imwechete Fafgerantifendents, isiri-inosanganiswa mafiriji, uye anofashama akasanganiswa.
Kuumbwa kweiyo imwechete yekushandira Firtofiti hakuzoshandure kuti iri gaseous here kana kuti mvura, saka nyika yezasi inogona kubhadharwa firiji.
Kunyangwe kuumbwa kweFirifiti yeiyo azotropic yakasiyana, nekuti point point yakafanana, kuumbwa kwegesi nemvura kwakafananawo, saka gasi rinogona kupomerwa;
Nekuda kweiyo dzakasiyana-siyana dzinovhiya dzidziso dzisiri-dzisingafadzi, Liquid's LiquidRigerants uye mafashoni echiitiko chakasiyana chaizvo mukuumbwa. Kana mafashama econus achiwedzerwa panguva ino, kuumbwa kweanowedzera mafiriji kuchave kwakasiyana. Semuenzaniso, chete imwezve gaseousfigiri inowedzerwa. Fafiriji, saka mvura chete inogona kuwedzerwa.
Ndozviti, zvisiri-ezotropic zvifemo zvinofanirwa kuwedzerwa nemvura, uye isiri-yeotrootropic dzinopiwaiti zvese kutanga ne r4. Rudzi urwu rwemvura runowedzerwa. Zvakajairika zvisiri-ezotropic Dertigerants ndiro: R40, R401A, R403A, R07b, R407C, R410A
Kana zviri zvevamwe vanozivikanwa vanofadzwa, vakadai sa: R134A, R22, R29, R29, Rutivi rweFiriji harizobatwe nekuwedzera kwegesi kana mvura, saka zvakaringana.
Patinowedzera firiji, tinofanira kuteerera kune zvinotevera:
(1) Tarisa mabhuruku mune girazi rekuona;
(2) kuyera kumanikidza kwakakwirira uye kwakaderera;
(3) kuyera iyo compressor yazvino;
(4) kuyera jekiseni.
Mukuwedzera, inofanira kucherechedzwa uye kusimbisa kuti:
Isiri-Ezeotropic Refrigerants inofanira kuwedzerwa mumvura yemvura. Semuenzaniso, R410A Fafrigeran, kuumbwa kwayo kunoita zvinotevera:
R32 (DIFLOOOROMETHANCA): 50%;
R125 (PentafluoroThanee): 50%;
Nekuti mapoinzi ekubika eR312 uye r125 akasiyana cylinders akasara akamira, uye r125 r10% r105, nekuti iyo inovhara pfungwa yeR32 yakaderera, inopfuura iyo kumusoro chikamu chefrigetrant chikamu che r32.
Naizvozvo, kana gasara redigerant inowedzerwa, iyofrigedzera yakawedzerwa haisi r410a, asi R32.
Chechipiri, matambudziko akajairika ezviwi zvezviitiko
1. Liquid Fafigigerant Kutama
Firiji inotama inoreva kuunganidzwa kweiyo floodfirti yemvura mune compressor crankcase kana iyo compressor yakavharwa. Chero bedzi tembiricha mukati mekudzvinyirira inotonhorera kupfuura tembiricha mukati meiyo evaporator, musiyano wekumanikidza pakati pemuchenjerera uye anovhura anofambisa firiji nzvimbo. Ichi chiitiko chinonyanya kuitika munguva inotonhora. Nekudaro, nekuda kwemhepo yekudziya uye kupisa pombi, apo iyo curnensing unit iri kure necompressor, kutama kunogona kuitika kunyange kana tembiricha yakakwira.
Kana iyo system ikavharirwa, kana ikasatenderwa mukati memaawa mashoma, kunyangwe pasina mutsauko wekumanikidzwa, kutama kwechimwe chinhu kunogona kuitika nekuda kweiyo firiji mune frigent.
Kana iyo yakawandisa yemvura inofamba mu crankcase yecompressor.
2. Liquid Refigigerant kuyerera
Kana iyo yekuwedzera vavengi ikakundikana, kana iyo evaporator fan inokundikana kana kuvharirwa nemhepo firita, iyo flood flow ichafashukira mueverator uye pinda yemucheka kuburikidza nemucheka wekutakura mune yemvura pane mupfumi. Kana iyo yuniti ichimhanya, nekuda kwemvura inofashukira kuyerera kwemafuta, zvikamu zvinofamba zvemafuta zvinopfekwa, zvichikonzera chishandiso chekuchengetedza mafuta kuti chiite, nekukonzera crankcase kurasa mafuta. Mune ino kesi, kana muchina wakadzimwa, chiitiko cheferimendi yekufambisa chinozoitika nekukurumidza, zvichikonzera kusimuka kwemvura pane restart.

Kana iyo Svutugadzike inoitika, simbi yekurova ruzha kubva mukati meiyo compressor inogona kunzwiwa, uye inogona kuperekedzwa neyechisimba kwesimba re compressor. Liquid Slam inogona kukonzera vharuvhu pript Liquid Hammer inoitika kana iyo flood firiji inotamisa mu crankcase uye inotangazve. Mune mamwe mayuniti, nekuda kwekuputika kwemvura kana nzvimbo yezvinhu zvoga zvichaunganidza pombi kana evapirti panguva yekuvhara seyakawisira mvura yakachena uye pane yakanyanya kumhanya kana iyo unit yakavhurwa. . Iko kumhanya uye inertia yeiyo slam yemvura kwakakwanira kukunda chero dudziro yekudzivirira-mukudzivirira kubva kune yakasviba slam.
