Chifukwa chiyani valavu yowonjezera ya mufiriji iyenera kukhala pambuyo pa condenser ndi pamaso pa evaporator?

Izi zimatsimikiziridwa ndi ntchito yake. Popeza kuti valavu yowonjezera ndi valve, ngati kutsegula ndi kutseka digiri yake ndi nthawi yoyenera, komanso ngati evaporator ikhoza kumaliza ntchito ya evaporation nthawi zonse, imakhala ndi mgwirizano wofunikira kwambiri komanso wolunjika. Ngati firiji ikuwonjezeka Valavu imayikidwa pamaso pa condenser ya firiji, ndipo ntchito yake iyenera kukhala yolamulira kukula kwa mpweya wa condenser, koma kwenikweni, condenser sichifuna kuletsa kukula kwa mpweya wa firiji.

Kumbali ina, ngati valavu yowonjezera imayikidwa pambuyo pa evaporator, udindo wake uyenera kukhala wowongolera kuchuluka kwa mpweya wa refrigerant womwe umalowa kumapeto kwa compressor. Izinso zilibe tanthauzo. Mu dongosolo lonse firiji mkombero, m`pofunika kulamulira otaya refrigerant. Pali evaporator yokha. Poyang’anira kuchuluka kwa madzi omwe amaperekedwa kwa evaporator, condenser imatha kugwira ntchito “mulingo woyenera”, zomwe zingakhudze ntchito yabwino ya compressor.

Koma musaiwale kuti valavu yowonjezera si chigawo chodziimira. Ndi “dongosolo”, kachitidwe kamene kamayikidwa mufiriji. ntchito yake yaikulu ndi kudziwa kutentha kwa mpweya refrigerant kutulutsidwa evaporator, ndiyeno ntchito deta kudziwa kukula. Kukula kwa “kuchuluka” kwa firiji yamadzimadzi yoperekedwa ndi valavu kwa evaporator kunganenedwe kuti ndikofunikira ndipo malo a gawo lililonse mufiriji yonse ndiyofunikira.
