01 Intshayelelo epholileyo
Ukupholisa, njengoko negama libonisa, yinto engamanzi esetyenziselwa ukugcina ingqele, kufuneka ibe namandla okugcina ukubanda.Kukho into kwindalo esisipholisi esilungileyo, oko kukuthi amanzi.Kuyaziwa ukuba amanzi aya kuba ngumkhenkce ebusika xa ubushushu bungaphantsi kwe-0 °C.Ngokwenyani, inkqubo yokukhenkceza kukuba amanzi alulwelo aguqulwa abe ngamanzi aqinileyo kwindawo yokugcina amandla abandayo.Ngethuba le nkqubo, iqondo lokushisa lomxube wamanzi omkhenkce liya kuhlala kwi-0 ° C de amanzi atshintshe ngokupheleleyo emkhenkceni, ngelo xesha ukugcinwa kwamanzi okubandayo kuphelile.Xa ubushushu bangaphandle bomkhenkce obunjiweyo bungaphezulu kwe-0 ° C, umkhenkce uya kutsala ubushushu bemekobume kwaye ngokuthe ngcembe unyibilike emanzini.Ngethuba lenkqubo yokuchithwa, iqondo lokushisa lomxube wamanzi e-ice lihlala li-0 ° C de i-ice inyibilike ngokupheleleyo emanzini.Ngeli xesha, amandla abandayo agcinwe emanzini akhululiwe.
Kule nkqubo ingentla yotshintsho phakathi komkhenkce namanzi, iqondo lobushushu bomxube wamanzi omkhenkce lihlala liku-0 ℃ kwaye liya kuhlala ixesha elithile.Oku kungenxa yokuba amanzi yimathiriyeli yokutshintsha kwesigaba ku-0 ℃, ebonakala ngokutshintsha kwesigaba.Ulwelo luba luqilima (exothermic) , oluqinileyo luba lulwelo (endothermic), kwaye ubushushu abuyi kutshintsha kangangexesha elithile kwindawo yokutshintsha kwesigaba ngexesha lotshintsho lwesigaba (oko kukuthi, luya kutsala ngokuqhubekayo okanye lukhulule isixa esikhulu. lobushushu ngexesha elithile).
Esona sicelo siqhelekileyo sokutshintsha kwesigaba sokupholisa kubomi bethu bemihla ngemihla "kukugcinwa" kweziqhamo, imifuno kunye nokutya okutsha.Oku kutya kulula ukuwohloka phantsi kobushushu obuphezulu be-ambient.Ukwandisa ubutsha, sinokusebenzisa inguqu yesigaba sokupholisa ukulungelelanisa ubushushu bendawo ukufezekisa isiphumo solawulo lobushushu kunye nokugcinwa:
02 Aisicelo seKubanda Ci-oolant
Kwiziqhamo, imifuno kunye nokutya okutsha okudinga i-0 ~ 8 ℃ yokugcina ebandayo, iipakethe zomkhenkce ezipholileyo ziya kukhenkcezwa ku -7 ℃ ubuncinane iiyure ezili-12 (ukuqinisekisa ukuba iipakethe zomkhenkce ezipholileyo zinomkhenkce ngokupheleleyo) phambi kokusasazwa.Ngexesha lokusasazwa, iipakethe zomkhenkce zokupholisa kunye nokutya kuya kufakwa kwibhokisi yokupholisa kunye.Ibhokisi inkulu kwaye ixesha lokugquma lide, kokukhona iipakethe zomkhenkce ziya kusetyenziswa.Inkqubo yokusebenza ngokubanzi imi ngolu hlobo lulandelayo:
03 Aisicelo seUkupholisa okuMkhenkce
Ukutya okutsha okunomkhenkce okudinga i-0 ℃ yokugcina ebandayo, iipakethe zomkhenkce ezifakwe efrijini ziya kukhenkcezwa ku -18 ℃ ubuncinane iiyure ezili-12 (ukuqinisekisa ukuba iipakethe zomkhenkce ezikhenkcezisiweyo zikhenkceke ngokupheleleyo) phambi kokuba zisasazwe.Ngexesha lokusasazwa, iipakethi zomkhenkce ezifakwe efrijini kunye nokutya kuya kufakwa kwi-incubator kunye.Okukhona i-cooler box inkulu kwaye ixesha lokugquma lide, kokukhona iipakethe zomkhenkce ziya kusetyenziswa.Inkqubo yokusebenza ngokubanzi imi ngolu hlobo lulandelayo:
04 Ukwakheka okupholileyo kunye neengcebiso zokuSebenzisa
Ngenkqubela phambili yoluntu, umgangatho wobomi babantu uya unyuka ngokunyuka, kwaye ukuphindaphindwa kokuthengwa kwe-intanethi kwixesha le-Intanethi kuyanda.Ukutya okuninzi okutsha kunye nomkhenkce kulula ukuwohloka kuthutho olucacileyo ngaphandle "kokulawula ubushushu kunye nokugcinwa".Ukusetyenziswa kwe "phase change coolant" ibe lolona khetho lulungileyo.Emva kokuba ukutya okutsha kunye nomkhenkce kulawulwe kakuhle kwaye kugcinwe kukutsha, umgangatho wobomi babantu uphuculwe kakhulu.
Ngokusetyenziswa rhoqo kwe-0 ℃ kunye neepakethe zomkhenkce ezikhenkcezileyo, ngaba ukupholisa okuvuzayo ekugqabhukeni kweepakethe zomkhenkce ngexesha lothutho kuya kuba sisoyikiso kukhuseleko lokutya?Ngaba iya kubangela ingozi kumzimba womntu ukuba ityiwe ngaphandle kokwazi?Ukuphendula kwezi ngxaki, senza le miyalelo ilandelayo yeepakethe zomkhenkce:
