Iyo yekukurumidza firiza inoumbwa nezvikamu zvishanu munhevedzano: compressor, condenser, evaporator, yakaoma sefa, uye yekuwedzera throttle valve.Huwandu hwakakodzera hwefiriji hunoiswa mukati mayo, uye mudziyo wemagetsi unodzora kushanda kwecompressor zvinoenderana nezvinodiwa nenharaunda kuti uwane firiji uye kupisa kupisa.chinangwa che.
compressor
Muchina unotyairwa wemvura unosimudza yakaderera gasi kune yakanyanya kudzvanywa.Iyo inokurumidza friza ndiyo moyo wefiriji system.Iyo inofema yakadzika-tembiricha uye yakaderera-kudzvanya refrigerant gasi kubva papombi inokweva, inotyaira piston kuti iite kuti isimbise kuburikidza nekushanda kwemota, uye inoburitsa yakakwirira-tembiricha uye yakanyanya-kudzvanywa refrigerant gasi kune yekuburitsa pombi kuti ipe simba refiriji. cycle.Nenzira iyi, kutenderera kwefiriji yekumanikidza → kukwidziridza → kuwedzera → kunyungudika (kupisa kupisa) kunoitika.
condenser
Iyo yakanyanya-tembiricha uye yakakwirira-kumanikidza refrigerant mhute inoburitswa kubva mucompressor inodzorwa kuita yemvura mufiriji kuburikidza nekupisa kwekupisa, uye kupisa kunotorwa nefiriji kubva kune evaporator kunotorwa nepakati (atmosphere) yakatenderedza condenser.
Evaporator
Iyo liquid refrigerant inoshandurwa kuita gaseous state pano.
sefa dryer
Muchirongwa chefiriji, basa refiriji yakaoma nderekutora unyoro mufiriji system, kuvhara kusvibiswa muhurongwa kuti husakwanise kupfuura, uye kudzivirira kuvharika kwechando uye kuvharika kwakasviba mufiriji system pombi.Sezvo iyo capillary (kana kuwedzera valve) ndiyo inonyanya kuvharika chikamu chegadziriro, iyo yakaoma sefa inowanzoiswa pakati pe condenser uye capillary (kana kuwedzera valve).
Kuwedzera throttle valve
Kudonhedza uye kudzvinyirira iyo yakakwirira-kudzvanywa kwemvura refrigerant kubva kune yemvura yekuchengetedza yakaoma, kugadzirisa uye kudzora huwandu hwemvura yefiriji inopinda muevaporator, kuitira kuti ienderane nekuchinja kwemutoro wefiriji, uye panguva imwechete kudzivirira iyo yemvura sando chiitiko cheiyo. compressor uye mhute panobuda evaporator Abnormal overheating.
