Iikomityi zamanzi ezingenasici zisisitya esiqhelekileyo sokugcina ubushushu, kodwa ngenxa yenani elikhulu leemveliso kwiimarike, ixesha lokulondoloza ubushushu liyahluka.Eli nqaku liza kwazisa imigangatho yamazwe ngamazwe ngexesha lokugquma kweebhotile zamanzi zensimbi engenasici kwaye lixoxe ngezinto ezichaphazela ixesha lokugquma.
Njengesitya esiqhelekileyo sokufakelwa kwe-thermal, iikomityi zamanzi zensimbi ezingenasici zithandwa ngabathengi.Nangona kunjalo, iimpawu ezahlukeneyo kunye neemodeli zeebhotile zamanzi zensimbi ezingenasici zineeyantlukwano kubude bexesha ezinokugcinwa zifudumele, ezizisa ingxaki kubathengi ekukhetheni imveliso efanelekileyo.Ukuze kuqinisekiswe umgangatho wemveliso kunye nokubonelela ngezalathi ezichanekileyo zereferensi, i-International Standards Organisation iye yaqulunqa imigangatho yexesha lokufakelwa kweebhotile zamanzi zensimbi ezingenasici.
Ngokwemigangatho yamazwe ngamazwe, ixesha lokugcinwa kobushushu kwiibhotile zamanzi zensimbi engenasici kufuneka lihlangabezane nezi mfuno zilandelayo:
1. Imigangatho yokugquma isiselo esishushu: Kwiikomityi zamanzi zensimbi ezingenasici ezilayishwe ngeziselo ezishushu, ixesha lokugquma kufuneka libe ngaphezu kweeyure ezi-6.Oku kuthetha ukuba emva kweeyure ezi-6 emva kokuzaliswa ngesiselo esishushu, iqondo lobushushu lolwelo kwikomityi yamanzi kufuneka libe liphezulu okanye lisondele kwiqondo lobushushu elimiselweyo.
2. Imigangatho yokugquma isiselo esibandayo: Kwiikomityi zamanzi zensimbi ezingenasici ezilayishwe ngeziselo ezibandayo, ixesha lokugquma kufuneka libe ngaphezu kweeyure ezili-12.Oku kuthetha ukuba emva kweeyure ezili-12 emva kokuzaliswa ngesiselo esibandayo, ubushushu bolwelo kwikomityi yamanzi kufuneka bube bungaphantsi okanye busondele kubushushu obumiselweyo.
Kufuneka kuqatshelwe ukuba imigangatho yamazwe ngamazwe ayichazi amaxabiso athile obushushu, kodwa ibeka iimfuno zexesha ezisekelwe kwiimfuno zesiselo esiqhelekileyo.Ke ngoko, amaxesha athile okugquma anokwahluka ngokuxhomekeke kwizinto ezifana noyilo lwemveliso, umgangatho wemathiriyeli kunye neemeko zokusingqongileyo.
Izinto ezichaphazela ixesha lokugcinwa kobushushu kwiibhotile zamanzi zensimbi ezingenasici ziquka:
1. Isakhiwo somzimba wendebe: I-double-layer okanye i-three-layer yesakhiwo sendebe yamanzi inokubonelela ngesiphumo esingcono sokugcina ubushushu, ukunciphisa ukuqhuba ubushushu kunye nemitha, ngaloo ndlela ukwandisa ixesha lokugcinwa kobushushu.
2. Ukusebenza kokutywina kwesiciko sekomityi: Ukusebenza kokutywinwa kwesiciko sekomityi kuchaphazela ngokuthe ngqo isiphumo sokugcina ubushushu.Ukusebenza kakuhle kokutywina kunokuthintela ukulahleka kobushushu okanye umoya obandayo ukuba ungangeni, uqinisekisa ixesha elide lokugcinwa kobushushu.
3. Ubushushu be-ambient yangaphandle: Ubushushu be-ambient yangaphandle bunempembelelo ethile kwixesha lokugcinwa kobushushu bekomityi yamanzi.Kwiindawo ezibanda kakhulu okanye ezishushu kakhulu, ukugquma kungasebenza kancinci kancinci.
4. Ubushushu bokuqalisa kolwelo: Iqondo lobushushu lokuqala lolwelo kwikomityi yamanzi nalo liya kuchaphazela ixesha lokubamba.Ulwelo oluphezulu lobushushu luya kuba nokuhla okubalulekileyo kobushushu ngexesha elithile.
Ngamafutshane, imigangatho yamazwe ngamazwe ichaza iimfuno zexesha lokugcinwa kobushushuiikomityi zamanzi ezingenasici, ukubonelela ngezalathi zereferensi kubathengi.Nangona kunjalo, elona xesha logcino lobushushu likwachatshazelwa zizinto ezininzi, kubandakanya ubume bomzimba wekomityi, ukusebenza kokutywinwa kwesivalo sekomityi, ubushushu obungaphandle kunye nobushushu bokuqala bolwelo.Xa kuthengwa iikomityi zamanzi zensimbi engenasici, abathengi kufuneka baqwalasele le miba ngokubanzi kwaye bathenge iikomityi ze-thermos zensimbi ezingenasici ngokusekelwe kwiimfuno zabo zexesha lokulondoloza ubushushu.
