Umoya opholileyo kwiimoto – Umgaqo wokuFrijisa

Isixhobo sokupholisa umoya semoto(isixhobo somoya opholileyo) sibizwa ngokuba yiumoya opholileyo wemotoIsetyenziselwa ukulungisa nokulawula ubushushu, ukufuma, ukucoceka komoya kunye nokuhamba komoya kwindawo yemoto ukuya kwimeko efanelekileyo, ukubonelela abakhweli ngendawo yokukhwela ekhululekileyo, ukunciphisa ukudinwa kokuhamba, kunye nokudala iimeko zokusebenza ezilungileyo kumqhubi. Ngokubanzi ibandakanya izixhobo zokukhenkcisa, izixhobo zokufudumeza kunye nezixhobo zokungenisa umoya.
Iumoya opholileyo wesithuthiInkqubo yokukhenkcisa iqulathe icompressor, i-condenser, i-liquid storage dryer, i-expansion valve, i-evaporator kunye ne-blower. Ezi zinto ziqhagamshelwe ukwenza inkqubo evaliweyo eneetyhubhu zobhedu (okanye iityhubhu ze-aluminium) kunye neetyhubhu zerabha ezinoxinzelelo oluphezulu. Xa inkqubo yokukhenkcisa isebenza, i-refrigerant ijikeleza kule nkqubo ivaliweyo kwiimeko ezahlukeneyo. Umjikelo ngamnye uneenkqubo ezine ezisisiseko:

(1) Inkqubo yokucinezela: I-compressor iphefumla igesi yefriji enobushushu obuphantsi kunye noxinzelelo oluphantsi kwindawo yokuphuma ye-evaporator, iyicinezele ibe yigesi yefriji enobushushu obuphezulu kunye noxinzelelo oluphezulu kwaye iyikhuphe kwi-compressor.

(2) Inkqubo yokusasaza ubushushu: Igesi yefriji eshushu kakhulu enobushushu obuphezulu kunye noxinzelelo oluphezulu ingena kwi-condenser. Ngenxa yokwehla koxinzelelo kunye nobushushu, igesi yefriji ijika ibe lulwelo kwaye ikhuphe ubushushu obuninzi.

(3) Inkqubo yokufunxa: Emva kokuba ulwelo olubandayo olunobushushu obuphezulu kunye noxinzelelo ludlule kwisixhobo sokwandisa, umthamo walo uyanda, kwaye uxinzelelo lwalo kunye nobushushu behla kakhulu, kwaye lukhutshwa kwisixhobo sokwandisa ngendlela yenkungu (amathontsi amancinci).

(4) Inkqubo yokufunxa ubushushu: Ulwelo lwe-refrigerant oluphuma kwi-evaporator lungena kwi-evaporator. Ekubeni iqondo lokubila kwe-refrigerant liphantsi kakhulu kunobushushu obungaphakathi kwi-evaporator, ulwelo lwe-refrigerant luyajika lube yi-gesi. Ngexesha lenkqubo yokufunxa, lufunxa ubushushu obuninzi obujikelezileyo, uze emva koko umphunga we-refrigerant ophuma kwi-compressor ungene kwakhona. Le nkqubo ingasentla iphindaphindwa kaninzi ukufezekisa injongo yokunciphisa ubushushu bomoya obujikeleze i-evaporator.
