Mafiriji anoshandiswa zvakanyanya mudzimba nemabhizimisi kuti abatsire kuchengetedza chikafu chitsva kwenguva yakareba, uye kudzivirira kuora kwechinhu kuti chiparadze. Nefiriji yekutengeserana, mhando yechikafu inogona kuchengetedzwa kwenguva yakareba, kunyanya kumasupamaketi kana maresitorendi, vanofanirwa kuchengetedza chikafu nechinwiwa chakawanda, kuva nefiriji kunogona kuva nechokwadi chekuti vane zvekushandisa zvakakwana kuti vashandise vatengi vavo. Zvisinei, kunyangwe tine firiji, mamwe marara asingadiwe uye kurasikirwa dzimwe nguva kunoitika nekuda kwekushandiswa zvisina kunaka kana kugadziriswa. Kuti tive nechokwadi chekuti michina yedu yekufiriji inoshanda zvakanaka, tinofanira kudzidza musimboti wayo wekushanda kuti ibatsire kuchengetedza chikafu zvakanaka.
Sei Kudzidza Nheyo Inoshanda yeRefrigeration Kwakakosha?
Sisitimu yekutonhodza inoshanda sei? Nheyo yekushanda yekutonhodza yakavakirwa pasisitimu yekufamba kwebhasikoro, iyo ine refrigerant yakavharirwa mukati mayo uye inosundirwa kuti ifambe kubva pa evaporator kuenda kune condenser mumhando dzakasiyana. Sisitimu yakadaro iri kushanda nechinangwa chekutonhodza tembiricha muchikamu chekuchengetera. Kudzidza kuti yakofiriji yekutengeseranaKushanda kwemidziyo kunobatsira kuti uzive kupisa kuti uchenese uye uchengetedze hurongwa hwefiriji zvinobudirira. Nekunzwisisa musimboti wekushanda uye ruzivo rwefiriji, uchabatsirwa nekushanda zvakanaka kwemidziyo yako. Semuenzaniso, kudzidza kuisa firiji yako yebhizinesi munzvimbo yekufema kunogona kubatsira kudzivirira kushanda kwayo zvakanyanya uye kuderedza kushandiswa kwesimba remagetsi.
Ndezvipi zvinhu zvinosanganisirwa muRefrigeration System?
Sezvambotaurwa pamusoro apa, firiji sisitimu yekufamba nemhepo inosanganisira zvimwe zvikamu zvemakanika nezvikamu, zvinosanganisira compressor, condenser, expansion/throttle valve, evaporator, nezvimwewo. Pamusoro pezvo, firiji ndiyo chinhu chakakosha kuendesa kupisa kwemukati kune condenser kunze. Chikamu chimwe nechimwe chine basa rayo rekusundidzira refrigerant kuti ifambe yakatenderera musystem iyi yekufamba nemhepo, uye refrigerant inoshandurwa kuita gasi kana mvura, kufamba uku kunogona kukonzera kuti kutonhora kudonhedze tembiricha yekuchengetera.
Ngatidzidzei zvakawanda nezvezvinhu zvinoisa mufiriji.
Compressor
Compressor inoonekwa sesimba rekusundidzira refrigerant kuti ifambe mufiriji, uye chikamu ichi chinosanganisira mota yekukwevera utsi hwerefrigerant kubva mu evaporator nekuhudzvanya mu cylinder kuti iwedzere tembiricha nekumanikidzwa kwayo, kuitira kuti utsi hwerefrigerant hugone kupfaviswa zviri nyore nemhepo nemvura netembiricha yemumba kana hwasundirwa ku condenser.
Chinotonhodza
Condenser mudziyo wekuchinjana kupisa, une machubhu coil nemafin akaiswa kumashure kana kumativi efiriji. Kana mhute yefiriji ine kumanikidzwa kwakanyanya uye tembiricha inopfuura pano, inozobatanidzwa kuti ishanduke kuita chimiro chemvura ine tembiricha yemukamuri, asi refrigerant yemvura ichiri kuuya ne high-pressure.
Vharuvhu Yokuwedzera
Muchina wemvura usati wapinda mu evaporator, kumanikidzwa kwawo netembiricha zvinodhonzwa kusvika padanho rekuwandisa nevharuvhu yekutambanudza mvura kana uchiyerera. Kudzikira kamwe kamwe kwetembiricha nekumanikidzwa kunogona kukonzera kuti mvura ipinde mufiriji.
Muchina wekupwanya mvura
Evaporator mudziyo wekuchinjana kupisa. Mvura inotonhorera ine tembiricha yakaderera uye kumanikidzwa kunoyerera mumudziyo uyu kuti iparadzwe kuita utsi, iyo inotora kupisa kwemhepo iri mufiriji, maitiro akadaro anobatsira pachinangwa chikuru chekutonhodza chikafu nezvinwiwa zvakachengetwa. Kana refrigerant iri mu evaporator yakaderera, tembiricha yezvinhu zvakachengetwa inodererawo.
Sisitimu yeRefrigeration Inoshanda Sei?
Zvinhu zvataurwa pamusoro apa zvinobatwa nemachubhu kuti zvigadzire sisitimu yekufamba nemhepo. Kana sisitimu ichishanda, compressor inofema mweya wefriji une tembiricha yakaderera uye ine pressure yakaderera unogadzirwa ne evaporator mu cylinder. Kana kumanikidzwa (tembiricha ikakwirawo) kwakakura zvishoma pane kumanikidzwa kuri mu condenser, mhepo ine pressure yepamusoro iri mu cylinder inotumirwa ku condenser. (saka, kuti iite basa rekudzvanya uye kutumira compressor yefriji) mukati me condensing refrigerant ye tembiricha yepamusoro uye pressure yakakwirira uye mhepo ine tembiricha yakaderera (kana mvura) patembiricha yekamuri kuti ipfuure kupisa uye condensation ye liquid refrigerant, mvura inotonhorera mushure mekutonhodza vharuvhu yekuwedzera (buck) ichipinda mu evaporator, mukati me evaporator inotora kupisa uye yobva yaita vaporizing chinhu kuti chitonhodze. Nenzira iyi, chinhu chinotonhorera chinotonhorera uye vaporizing inosvetwa ne compressor, saka mu refrigerant system kuburikidza nekudzvanya, condensation, expansion, evaporation yemaitiro mana kuti ipedzise cycle.
