IyoMafiriji akamirauye mafiriji akatambarara ari pamusika anoshandisa kutonhodza mhepo, kutonhora, nezvimwewo, asi ese ari marudzi akasiyana emafiriji eR600A neR134A. Ehe, "catalyst" pano inoreva kutamiswa kwesimba, kureva, kupfuta uye kudziya kuti kupisa kutamiswe. Kune vanhuwo zvavo, tinongoda kunzwisisa kuti chikamu chakakosha chekutonhodza firiji.
Kuti zvive nyore kwauri kunzwisisa, musimboti wekutanga wekuisa firiji unoenderana nekuchinja kweCarnot kuburikidza nematanho mana akakosha:
(1) Kudzvanywa (kupisa kwakanyanya uye gasi rinomanikidzwa zvakanyanya)
Compressor inodzvanya gasi refriji rine tembiricha yakaderera uye ine pressure yakaderera kuita gasi rine tembiricha yepamusoro uye ine pressure yakakwirira, zvichiita kuti tembiricha yaro ikwire zvakanyanya (semuenzaniso kubva -20 ° C kusvika 100 ° C).
(2) Kunyungudika (kupisa kunoshanduka kuita mvura)
Gasi rinopisa zvakanyanya uye rinomanikidzwa zvakanyanya rinopinda mu condenser, roburitsa kupisa kuburikidza nefeni inotonhodza, uye rinoshanduka kuita tembiricha yakajairika uye mvura inomanikidzwa zvakanyanya mushure mekutonhodza.
(3) Kuwedzera (kuderedzwa kwekumanikidzwa kwekuvapo kwemhepo mu endothermic)
Mushure mekunge mvura ine simba rakawanda yapfuura nepavharuvhu yekutambanudza, simba rinodzikira zvakanyanya, richipwanyika zvishoma uye richitora kupisa kwakatenderedza evaporator, zvichiita kuti mukati mefiriji mutonhore.
(4) Kubuda kwemvura (tembiricha yakaderera uye gasi rine simba shoma)
Mvura inotonhorera patembiricha yakaderera uye kumanikidzwa kunopfuta zvachose mu evaporator, yotora kupisa kuri mufiriji, yozodzokera ku compressor kuti ipedzise kutenderera.
Panguva ino, basa guru remufiriji rinoratidzwa mukutorwa kwekupisa kwechikamu uye exotherm, uye maitiro ekutorwa kwekupisa kwevaporization achatonhodza firiji.
Cherechedza:Refrigerant inodzokororwazve muchimiro chakavharwa uye inoshandiswa kakawanda isina kudyiwa. Hunhu hwayo hwepanyama (semuenzaniso kufashaira kushoma, kupisa kwakanyanya kwakavanzika) hunoratidza kushanda zvakanaka kwekutonhodza.
Pano ndinoda kukutsanangurirai kuti vashandisi vanogona kuvhiringa pfungwa ye "catalyst" ne "medium". Mafiriji haabatanidzwe mukuita kwemakemikari, asi anotamisa simba kuburikidza nekuchinja kwechikamu chemuviri, asi mashandiro awo anokanganisa zvakananga mhedzisiro yekutonhora (senge kushanda zvakanaka, tembiricha), sekukosha kwezvinokonzera mukuita kwemakemikari, asi nzira mbiri idzi dzakasiyana zvachose.
Zvimiro:
(1) Zviri nyore kupfavisa uye kunwisa kupisa patembiricha yemumba (semuenzaniso R600a boiling point – 11.7 ° C), ine makemikari akasimba, uye haisi nyore kuora kana ngura michina.
(2) Hushamwari kune zvakatipoteredza: Deredza kukuvara kwe ozone layer (semuenzaniso R134a inotsiva R12).
Mafiriji ndiwo musimboti wekushandiswa kwefiriji yekutengeserana. Anotamisa kupisa kuburikidza nekuchinja kwechikamu, zvakafanana ne "heat porters", ayo anoburitsa kupisa mukati mefiriji kuenda kunze nekutenderera, nokudaro achichengetedza tembiricha yakaderera.
