Izixhobo zoTshintsho lweSigaba (i-PCMs) luhlobo olukhethekileyo lwezinto ezinokufunxa okanye zikhulule umthamo omkhulu wamandla ashushu kwiqondo elithile lobushushu, ngelixa uphantsi kotshintsho kwimo yenyama, njengokusuka kwiqina ukuya kulwelo okanye ngokuphambeneyo.Le propati yenza izinto zokutshintsha kwesigaba zibe nexabiso lesicelo esibalulekileyo ekulawuleni ukushisa, ukugcinwa kwamandla, kunye nemimandla yokulawula i-thermal.Oku kulandelayo luhlalutyo oluneenkcukacha lwezixhobo zokutshintsha isigaba:
impahla ebonakalayo
Uphawu oluphambili lwezinto zokutshintsha kwesigaba kukukwazi ukufunxa okanye ukukhulula inani elikhulu lobushushu obufihliweyo kwiqondo lokushisa elingaguqukiyo (iqondo lokutshintsha kwesigaba).Kwinkqubo yokufunxa ubushushu, izinto ziyatshintsha ukusuka kwesinye isigaba ukuya kwesinye, njengokusuka kukuqina ukuya kulwelo (ukunyibilika).Ngexesha lenkqubo ye-exothermic, izinto eziphathekayo zitshintsha ukusuka kwi-liquid ukuya kwi-solid (ukuqina).Le nkqubo yenguqu yesigaba idla ngokwenzeka ngaphakathi kuluhlu olumxinwa kakhulu lobushushu, luvumela izinto zokutshintsha isigaba ukuba zibe nokuzinza okuhle kwe-thermal kumaqondo obushushu angaguqukiyo.
Iintlobo eziphambili
Izinto zokutshintsha isigaba zinokuhlelwa ngokwezi ndidi zilandelayo ngokusekwe kwiipropati zabo zekhemikhali kunye nemimandla yesicelo:
1. IiPCM ze-Organic: kubandakanywa iparafini kunye neeasidi ezinamafutha.Ezi zixhobo zinozinzo oluhle lweekhemikhali, ukuphinda zisebenziseke, kunye noluhlu olufanelekileyo lwamaqondo obushushu besigaba.
2. IiPCM ezingaphiliyo: kubandakanywa izisombululo ze-saline kunye neengqungquthela zetsimbi.I-conductivity yabo ye-thermal idla ngokuba ngcono kune-PCM eziphilayo, kodwa banokujamelana nemiba yokwahlukana kunye ne-corrosion.
3. Ii-PCM ze-Biobased: Olu luhlobo oluvelayo lwee-PCM ezivela kwi-biomaterials yendalo kwaye zineempawu zokusingqongileyo kunye nezizinzileyo.
indawo yesicelo
Izixhobo zokutshintsha isigaba zisetyenziswa ngokubanzi kwiinkalo ezininzi, ingakumbi ezibandakanya:
1. Ukwakha amandla okusebenza kakuhle: Ngokudibanisa ii-PCM kwizinto zokwakha ezifana neendonga, imigangatho, okanye iisilingi, ubushushu bangaphakathi bunokulawulwa ngokufanelekileyo, kuncitshiswe ukusetyenziswa kwamandla kwi-air conditioning kunye nokufudumeza.
2. Ukugcinwa kwamandla okushisa: Ii-PCM ziyakwazi ukutshisa ukushisa kwiqondo lokushisa eliphezulu kwaye zikhulule ukushisa kumaqondo aphantsi, kunceda ukulungelelanisa ukunikezelwa kwamandla kunye nokufunwa, ngokukodwa ekusebenziseni amandla avuselelekayo njengamandla elanga kunye nomoya.
3. Ulawulo lwe-thermal yeemveliso zombane: Ukusebenzisa ii-PCM kwizixhobo zombane kunokunceda ukulawula ukushisa okwenziwa ngexesha lokusebenza, ukuphucula ukusebenza kakuhle, kunye nokwandisa ixesha lokuphila kwesixhobo.
4. Ukuthutha kunye nokupakishwa: Ukusetyenziswa kwe-PCM ekutyeni nasekuthuthweni kwamayeza kunokugcina iimveliso phantsi kweemeko ezifanelekileyo zokushisa kunye nokuqinisekisa umgangatho wemveliso.
Imingeni yobugcisa
Ngaphandle kweenzuzo ezibalulekileyo zezinto zokutshintsha kwesigaba, basajongene nemingeni ethile yobugcisa kwizicelo eziphathekayo, ezifana nexesha lokuphila, ukuzinza kwe-thermal, kunye nesidingo sokupakisha kunye nokudibanisa iteknoloji.Le mingeni kufuneka yoyiswe ngokuhambela phambili kwisayensi yezixhobo kunye nobuchwephesha bobunjineli.
Izinto zokutshintsha isigaba zilindeleke kakhulu kwiinkalo zamandla aluhlaza kunye nobuchwepheshe obuzinzileyo ngenxa yokusebenza kwabo okukhethekileyo kwe-thermal kunye nethemba elibanzi lesicelo.
