Basa rezvinhu zvikuru zvemuchina wekuomesa mufiriji

1. Compressor yefiriji

Macompressor emufiriji ndiwo musimboti wesystem yekutonhodza, uye macompressor mazhinji nhasi anoshandisa macompressor anodzokorodza anodziya. Kusimudza refrigerant kubva padanho rakaderera kusvika padanho rakakwirira uye kutenderera refrigerant nguva dzose, system inoramba ichiburitsa kupisa kwemukati kunzvimbo iri pamusoro petembiricha yesystem.

2. Chinotonhodza

Basa remuchina wekondensa nderekutonhodza utsi hwemufiriji hune simba guru, hunopiswa zvakanyanya hunoburitswa necompressor yemufiriji huchipinda mufiriji ine mvura, uye kupisa kwayo kunobviswa nemvura inotonhodza. Izvi zvinoita kuti maitiro ekufiriji arambe achienderera mberi.

3. Muchina wekupwanya mvura

Evaporator ndiyo inonyanya kushandisa kupisa mufiriji, uye mhepo yakamanikidzwa inotonhodzwa zvine simba mu evaporator, uye utsi hwakawanda hwemvura hunotonhodzwa uye hunoiswa mumvura ine mvura uye hunoburitswa kunze kwemuchina, kuitira kuti mweya wakamanikidzwa waome. Mvura ine pressure yakaderera inova utsi hwe refrigerant hune pressure yakaderera panguva yekuchinja kwechikamu mu evaporator, zvichitora kupisa kwakakomberedza panguva yekuchinja kwechikamu, nokudaro zvichitonhodza mweya wakamanikidzwa.

4. Vharuvhu yekuwedzera inodziya (capillary)

Vharuvhu yekuwedzera thermostatic (capillary) ndiyo nzira yekudzora thermostatic system. Mufiriji dryer, kuwanikwa kwe evaporator refrigerant ne regulator yayo kunoitika kuburikidza ne throttling mechanism. Nzira yekudzora thermostatic inobvumira firiji kupinda mu evaporator kubva mumvura inopisa uye ine pressure yakakwira.

5. Chinochinja kupisa

Mazhinji emafiriji anoomesa ane chinochinja-chinja kupisa, chinova chinochinja-chinja kupisa pakati pemhepo nemhepo, kazhinji chinochinja-chinja kupisa kwechubhu (chinozivikanwawo sechichinja-chinja kupisa kweshell nechubhu). Basa guru rechichinja-chinja kupisa mufiriji ndere "kudzoreredza" kugona kwekutonhodza kunotakurwa nemhepo yakamanikidzwa mushure mekutonhodzwa ne evaporator, uye kushandisa chikamu ichi chesimba rekutonhodza kutonhodza mhepo yakamanikidzwa patembiricha yepamusoro inotakura huwandu hwakawanda hwemvura (ndiko kuti, mhepo yakamanikidzwa yakasanganiswa inoburitswa mu air compressor, yakatonhodzwa nechinhu chinotonhodza chekumashure che air compressor, uye yozoparadzaniswa nemhepo nemvura kazhinji iri pamusoro pe40 °C), nokudaro ichideredza mutoro wekupisa wefriji nekuomesa system uye kuzadzisa chinangwa chekuchengetedza simba. Kune rumwe rutivi, tembiricha yemhepo yakamanikidzwa yakaderera mu heat exchanger inodzoserwa, kuitira kuti madziro ekunze epaipi inotakura mhepo yakamanikidzwa asakonzere "kutonhora" nekuda kwetembiricha iri pasi petembiricha yemhepo. Pamusoro pezvo, mushure mekunge tembiricha yemhepo yakamanikidzwa yakwira, hunyoro hwemhepo yakamanikidzwa mushure mekuomeswa hunodzikira (kazhinji pasi pe20%), izvo zvinobatsira kudzivirira ngura yesimbi. Vamwe vashandisi (semuenzaniso nemiti yekuparadzanisa mhepo) vanoda mhepo yakamanikidzwa ine hunyoro hushoma uye tembiricha yakaderera, saka muchina wekuomesa wefiriji hausisina muchina wekuomesa. Sezvo muchina wekuomesa wekupisa usina kuiswa, mhepo inotonhora haigone kudzokororwa, uye mutoro wekupisa wemuchina wekuomesa uchawedzera zvakanyanya. Muchiitiko ichi, simba remuchina wekuomesa wefiriji haringodi chete kuwedzerwa kuti ritsive simba, asiwo zvimwe zvikamu zvehurongwa hwese hwekuomesa (muchina wekuomesa, muchina wekuomesa uye muchina wekupomba) zvinoda kuwedzerwa zvinoenderana. Kubva pamaonero esimba rekudzosa, tinogara tichitarisira kuti tembiricha yekuomesa yemuchina wekuomesa wefiriji yakakwira, zviri nani (tembiricha yekuomesa yakakwira, zvichiratidza kudzoserwa kwesimba rakawanda), uye zvakanaka kuti pasave nemusiyano wekupisa pakati penzvimbo inopinzwa nekubuda. Asi kutaura chokwadi, hazvigoneke kuita izvi, kana tembiricha yekupinda kwemhepo iri pasi pe45°C, hazvishamisi kuti tembiricha yekupinda nekubuda kwemuchina wekuomesa firiji inosiyana ne15°C.

Kugadziriswa Kwemhepo Yakamanikidzwa

Mhepo yakamanikidzwa→ mafirita emakanika→ mafirita ekupisa (kupisa kunoburitsa), →maevaporators→ maparadzira egasi-mvura→ mafirita ekupisa (kupisa kunonyudza), → mafirita emakanika anoburitsa mvura → matangi ekuchengetera gasi

Kugadzirisa nekuongorora: chengetedza tembiricha yemuchina wekuomesa firiji iri pamusoro pe zero.

Kuti kuderedze tembiricha yemhepo yakamanikidzwa, tembiricha yemvura inodziya yemufiriji inofanirawo kunge yakaderera. Kana muchina wekuomesa mufiriji uchitonhodza mhepo yakamanikidzwa, panenge paine jira remvura yakaita sefirimu pamusoro pechipete chemuchina we evaporator, kana tembiricha yemvura iri pasi pe zero nekuda kwekuderera kwetembiricha yemvura inodziya, mvura inodziya inogona kuoma, panguva ino:

A. Nekuda kwekunamirwa kwechando chine thermal conductivity diki pamusoro pechipete chemukati chedundira re evaporator, kushanda zvakanaka kwekuchinjana kwekupisa kunodzikira zvakanyanya, mhepo yakamanikidzwa haigone kutonhodzwa zvizere, uye nekuda kwekusakwana kwekupisa, tembiricha ye evaporation inotonhorera inogona kuderedzwa zvakanyanya, uye mhedzisiro yedenderedzwa rakadaro ichaunza mhedzisiro yakawanda yakaipa kune system ye refrigeration (senge "kumanikidzwa kwemvura");

B. Nekuda kwenzvimbo diki pakati pemafins ari mu evaporator, kana mafins aoma, nzvimbo inotenderera yemhepo yakamanikidzwa ichaderedzwa, uye kunyange nzira yemhepo ichavharwa muzviitiko zvakakomba, kureva kuti, "kuvharika kwechando"; Muchidimbu, tembiricha ye compression dew point ye refrigeration dryer inofanira kunge iri pamusoro pe 0 °C, kuitira kudzivirira tembiricha ye dew point kuti isanyanya kuderera, refrigeration dryer inopihwa energy bypass protection (inoitwa ne bypass valve kana fluorine solenoid valve). Kana tembiricha ye dew point yakaderera pane 0 °C, bypass valve (kana fluorine solenoid valve) inovhurwa yega (kuvhurika kunowedzera), uye isina kuvharwa high-temperature uye high-pressure refrigerant steam inopinzwa zvakananga mu inlet ye evaporator (kana gas-liquid separation tank pa compressor inlet), kuitira kuti dew point temperature ikwidzwe kusvika pamusoro pe 0 °C.

C. Kubva pamaonero ekushandiswa kwesimba remagetsi, tembiricha yemvura inobuda mumhepo yakaderera zvakanyanya, zvichikonzera kudzikira kukuru kwekodhereza yecompressor uye kuwedzera kwekushandiswa kwesimba.
