IIifriji ezime nkqokunye nezikhenkcezisi ezithe tyaba emarikeni zisebenzisa ukupholisa umoya, isikhenkcisi, njalo njalo, kodwa zonke ziindidi ezahlukeneyo zeefriji R600A kunye ne-R134A. Ngokuqinisekileyo, "i-catalyst" apha ibhekisela ekudlulisweni kwamandla, oko kukuthi, i-vaporization kunye ne-condensation ukuphumeza ukuhanjiswa kobushushu. Kubantu abaqhelekileyo, kufuneka siqonde kuphela ukuba yinxalenye ebalulekileyo yefriji yefriji.
Ukwenza kube lula kuwe ukuba uqonde, umgaqo osisiseko wefriji uxhomekeke kumjikelo weCarnot oguqukileyo ngamanyathelo amane aphambili:
(1) Uxinzelelo (ubushushu obuphezulu kunye negesi ephezulu yoxinzelelo)
Icompressor icinezela ubushushu obuphantsi kunye noxinzelelo oluphantsi lwegesi yefriji kwiqondo eliphezulu lobushushu kunye negesi ephezulu yoxinzelelo, ibangela ukuba ubushushu bayo bunyuke kakhulu (umzekelo ukusuka -20 ° C ukuya kwi-100 ° C).
(2) Ukujiya (ukuchithwa kobushushu kuba lulwelo)
Ubushushu obuphezulu kunye noxinzelelo oluphezulu lwegesi lungena kwi-condenser, lukhupha ubushushu nge-fan yokupholisa, kwaye lujike lube ngubushushu obuqhelekileyo kunye noxinzelelo oluphezulu lwamanzi emva kokupholisa.
(3) Ukwandiswa (ukuncitshiswa koxinzelelo lwe-vaporization endothermic)
Emva kokuba i-high-pressure liquide idlula kwi-valve yokwandisa, uxinzelelo lwehla ngokukhawuleza, ngokuyinxenye lube ngumphunga kwaye lufunxa ubushushu obujikeleze i-evaporator, ebangela ukuba ngaphakathi kwefriji kuphole.
(4) Umphumo (ubushushu obuphantsi kunye negesi yoxinzelelo oluphantsi)
Ulwelo lwefriji kwiqondo eliphantsi lobushushu kunye noxinzelelo lugutyungelwe ngokupheleleyo kwi-evaporator, lufunxa ubushushu kwifriji, luze lubuyele kwicompressor ukugqiba umjikelo.
Ngeli xesha, indima ephambili yefriji ibonakaliswe kwisigaba sokutshintsha ubushushu kunye ne-exotherm, kwaye inkqubo ye-vaporization yokushisa ukushisa iya kupholisa ifriji.
Phawula:Ifriji iphinda isetyenziswe kwinkqubo evaliweyo kwaye isetyenziswe ngokuphindaphindiweyo ngaphandle kokusetyenziswa. Iimpawu zayo ezibonakalayo (umzekelo, indawo yokubila ephantsi, ubushushu obuphezulu obufihlakeleyo) bumisela ukusebenza kakuhle kokupholisa.
Apha kufuneka ndikucacisele ukuba abasebenzisi banokubhidanisa ingcamango ye "catalyst" kunye "nophakathi". Iifriji azithatha inxaxheba kwiimpendulo zamakhemikhali, kodwa ukudlulisa amandla ngokuguqulwa kwesigaba somzimba, kodwa ukusebenza kwabo kuchaphazela ngokuthe ngqo umphumo wokupholisa (njengokusebenza kakuhle, ukushisa), njengokubaluleka kwee-catalysts kwi-chemical reactions, kodwa iindlela ezimbini zihluke ngokupheleleyo.
Iimbonakalo:
(1) Kulula ukufunxa nokufunxa ubushushu kwiqondo lobushushu begumbi (umz. i-R600a indawo yokubilisa – 11.7 ° C), inozinzo kwiikhemikhali, kwaye akukho lula ukubola okanye ukudleka kwezixhobo.
(2) Ukuvumelana nokusingqongileyo: Ukunciphisa umonakalo kucwecwe lwe-ozone (umz. i-R134a ithatha indawo ye-R12).
Iifriji zezona zinto ziphambili kwifriji yokuthengisa. Bahambisa ukushisa ngokutshintsha kwesigaba, kufana ne "heat porters", ekhupha ukushisa ngaphakathi kwefriji ukuya ngaphandle ngokujikeleza, ngaloo ndlela igcina indawo yokushisa ephantsi.
