Kodi mafiriji angagwiritse ntchito madzi ngati firiji?

Chifukwa madzi ali ndi izi:

Yoyamba, madzi, ndi yotsika mtengo kwambiri komanso yosavuta kupeza.

Poyerekeza ndi mafiriji akatswiri monga R12, R22, ndi R134a, madzi ndi otchipa komanso osavuta kupeza. Ichi ndi gawo lamadzi ngati firiji.

Chachiwiri, madzi sadzaphulika.

Monga tonse tikudziwa, poyerekeza ndi mafiriji okhala ndi ammonia, R12 ndi mafiriji ena opangidwa ndi freon amakhala otsika kwambiri komanso amatha kuphulika, chifukwa chake amakhala otetezeka kwambiri, koma ngati madzi agwiritsidwa ntchito ngati firiji, palibe kuthekera konse kophulika, kotero Palibe kukaikira za chitetezo. Titha kunena kuti ngati madzi agwiritsidwa ntchito ngati firiji, ayenera kukhala firiji yotetezeka kwambiri.

Komabe, madzi monga firiji ali ndi zoletsa zina. Mwachitsanzo, kutentha kwa madzi ngati firiji sikungakhale kutsika kuposa zero digiri Celsius. Ngati ndi yotsika kuposa zero madigiri Celsius, ifika pamadzi ozizira kwambiri, chifukwa chake siyingakhale yochepera kuposa zero madigiri Celsius. Dongosolo mufiriji amapereka utumiki, refrigerant! Chifukwa chomwe madzi sangagwiritsidwe ntchito m’mafiriji ama mafakitale ndichifukwa choti madzi sangagwiritsidwe ntchito pama compressor, kaya ndi screw compressor kapena piston compressor, madzi sangathe kugwira ntchito bwinobwino.

Zomwe zimapangitsa kuti madzi asamagwire bwino ntchito mu kompresa ndi chifukwa voliyumu yake ndiyokulirapo, kotero siyingagwiritsidwe ntchito kompresa. Pamapeto pake, kuthamanga kwamadzi kumakhala kotsika kwambiri, ndipo magwiridwe antchito a firiji sangatsimikizidwe. Palibe njira yoti madzi azigwiritsidwa ntchito nthawi zambiri ndi mafiriji.
