Ukungenisa umoya okubuyisela ubushushu kunye nokuphefumla kwakhona amandla kunokubonelela ngeenkqubo zokungenisa umoya ezixabisa iindleko ezikwanciphisa ukufuma kunye nokulahleka kobushushu.
Izinto ezilungileyo zokufudumeza kunye neenkqubo zokubuyisela umoya wokubuyisela amandla
1) banciphisa ilahleko yobushushu ngoko ke igalelo lobushushu elisezantsi (elisuka komnye umthombo) liyafuneka ukunyusa ubushushu bangaphakathi bufikelele kwinqanaba elitofotofo.
2) Amandla amancinci afunekayo ukuhambisa umoya kunokuwufudumeza
3) ezi nkqubo zezona zixabisa kakhulu kwisakhiwo esingenamoya kwaye xa zifakwe njengenxalenye yokwakhiwa kwendlu entsha okanye ukulungiswa okukhulu - azihlali zikulungele ukubuyisela kwakhona.
4) babonelela ngokungena komoya apho iifestile ezivulekileyo zinokuba yingozi kukhuseleko nakumagumbi angenafestile (umz. amagumbi okuhlambela angaphakathi kunye nezindlu zangasese)
5) banokusebenza njengenkqubo yokungenisa umoya ehlotyeni ngokudlula inkqubo yokuhambisa ubushushu kwaye ngokulula batshintshe umoya wangaphakathi kunye nomoya wangaphandle.
6) banciphisa ukufuma kwendlu ebusika, njengoko umoya opholileyo wangaphandle unomswakama ophantsi.
Indlela abasebenza ngayo
Iinkqubo zokungenisa umoya zokubuyisela ubushushu kunye neenkqubo zokungenisa umoya zokubuyisela amandla zifakwa kwiinkqubo zokungenisa umoya ezibandakanya iifeni ezimbini - enye yokutsala umoya ngaphandle kwaye enye isuse umoya odala wangaphakathi.
Isitshintshi sobushushu esisuka emoyeni sisemoyeni, esifakwe ngokubanzi kwindawo yophahla, sifumana kwakhona ubushushu obusuka kumoya wangaphakathi ngaphambi kokuba bukhutshelwe ngaphandle, kwaye sifudumeza umoya ongenayo ngobushushu obufunyenweyo.
Iinkqubo zokubuyisela ubushushu zinokusebenza kakuhle. I-BRANZ iqhube uvavanyo kwindlu yovavanyo kwaye ingundoqo iphinde yafunyanwa malunga ne-73% yobushushu obuvela kumoya ophumayo - ngokuhambelana nesiqhelo se-70% yokuphumelela kwee-cores ezinqamlezayo. Uyilo olunyamekileyo kunye nofakelo lubalulekile ekufezekiseni eli nqanaba lokusebenza kakuhle - ukusebenza kakuhle okunikezelweyo kunokwehla ngaphantsi kwe-30% ukuba i-ducting air kunye nelahleko yobushushu ayiqwalaselwa ngokufanelekileyo. Ngexesha lofakelo, ukuseta isicatshulwa esinokulinganisela kunye nokuhamba komoya wokungena kubalulekile ekufezekiseni ukusebenza kakuhle kwenkqubo.
Ngokufanelekileyo, zama kuphela ukubuyisela ubushushu kumagumbi apho ubushushu bomoya bungaphezulu kakhulu kobushushu bangaphandle, kunye nokuhambisa umoya ofudumeleyo kumagumbi agqunywe kakuhle ukuze ubushushu bungalahleki.
Iinkqubo zokubuyisela ubushushu ziyahlangabezana nemfuno yomoya omtsha wangaphandle wokungenisa umoya kwiKhowudi yeSakhiwo igatya le-G4 lokuPhumelela komoya.
Phawula: Ezinye iinkqubo ezitsala umoya endlwini ukusuka kwindawo yophahla ziyapapashwa okanye ziphakanyiswe njengeenkqubo zokubuyisela ubushushu. Umoya osuka kwindawo yophahla awukho umoya omtsha wangaphandle. Xa ukhetha inkqubo yokungenisa umoya yokubuyisela ubushushu, qinisekisa ukuba inkqubo ecetywayo ngokwenene ibandakanya isixhobo sokubuyisela ubushushu.
Iinkqubo zokungenisa umoya zokubuyisela amandla
Iinkqubo zokungenisa umoya zokubuyisela amandla ziyafana neenkqubo zokubuyisela ubushushu kodwa zihambisa umphunga wamanzi kwakunye namandla obushushu, ngaloo ndlela zilawula amanqanaba okufuma. Ehlotyeni, banokususa omnye umphunga wamanzi kumoya wangaphandle ogcwele ukufuma ngaphambi kokuba ungeniswe ngaphakathi; ebusika, banokudlulisela ukufuma kunye namandla obushushu kumoya obandayo ongenayo, owomileyo wangaphandle.
Iinkqubo zokubuyisela amandla ziluncedo kwiindawo eziphantsi kakhulu zokufuma apho kunokufuneka umswakama owongezelelweyo, kodwa ukuba ukususwa komswakama kuyafuneka, musa ukukhankanya inkqubo yokudlulisa ukufuma.
Ukulinganisa inkqubo
Imfuneko yeKhowudi yoKwakha yokungena komoya omtsha wangaphandle ifuna ukungena komoya kwindawo ekuhlala kuyo NZS 4303:1990 Ukungenisa umoya kumgangatho owamkelekileyo womoya wangaphakathi. Oku kubeka isantya kwi-0.35 yokutshintsha komoya ngeyure, elingana nesinye kwisithathu sawo wonke umoya wendlu oguqulwayo rhoqo ngeyure.
Ukugqiba ubungakanani benkqubo yokungenisa umoya efunekayo, bala umthamo wangaphakathi wendlu okanye inxalenye yendlu efunekayo ukuba ifakwe umoya kwaye uphindaphinde umthamo ngo-0.35 ukufumana umthamo omncinci wokutshintsha umoya ngeyure.
Umzekelo:
1)kwindlu enomgangatho ongama-80 m2 kunye nomthamo wangaphakathi we-192 m3 – phinda-phinda 192 x 0.35 = 67.2 m3/h
2)kwindlu enomgangatho ongama-250 m2 kunye nomthamo wangaphakathi we-600 m3 – phinda-phinda 600 x 0.35 = 210 m3/h.
Ukukhupha
Ukukhupha amanzi kufuneka kuvumele ukuxhathisa ukuhamba komoya. Khetha olona bungakanani bobungakanani bokutsala obunokwenzeka njengobukhulu bedayamitha yokutsala, kokukhona ukusebenza bhetele kokuhamba komoya kunye nokuthoba ingxolo yokuphuma komoya.
Ubungakanani bombhobho oqhelekileyo yi-200 mm ububanzi, ekufuneka isetyenziswe naphina apho kunokwenzeka, ukuncitshiswa ukuya kwi-150 okanye 100 mm idayamitha ekhokelela kwiiventi zesilingi okanye iigrili ukuba kuyimfuneko.
Umzekelo:
1)i-100 mm yesilingi ye-vent inokubonelela ngomoya owaneleyo ococekileyo kwigumbi elinomthamo wangaphakathi oyi-40 m.3
2)kwigumbi elikhulu, zombini iigesi zokuphuma kunye nokubonelela ngeesilingi okanye ii-grilles kufuneka zibe ubuncinane be-150 mm ububanzi - kungenjalo, iivents zesilingi ezimbini okanye ngaphezulu ze-100 mm ububanzi zingasetyenziswa.
Ukukhupha kufuneka:
I-1) ibe neendawo zangaphakathi ezigudileyo ngokusemandleni ukunciphisa ukuxhathisa ukuhamba komoya
2)ukuba nenani elincinci lokugoba kunokwenzeka
3)apho ukugoba kungenakuthintelwa, yiba nedayamitha enkulu kangangoko
4) ungabi namagophe aqinileyo njengoko oku kunokubangela ukuxhathisa okukhulu kokuhamba komoya
5)ifakwe i-insulated ukunciphisa ilahleko yobushushu kunye nengxolo yombhobho
6) ube ne-condensate drain ye-exhaust ducting ukuvumela ukususwa kokufuma okwenziwe xa ubushushu bususiwe emoyeni.
Ukungenisa umoya wokubuyisela ukushisa kwakhona kuyindlela yokukhetha igumbi elinye. Kukho iiyunithi ezinokuthi zifakwe kudonga lwangaphandle ngaphandle kwe-ducting efunekayo.
Ukubonelela kunye nokukhupha i-vents okanye i-grilles
Fumana ukubonelela komoya kunye neendawo zokukhupha umoya okanye iigrille ukwandisa ukusebenza kwenkqubo:
1) Khangela iindawo zokuvula iindawo zokuhlala, umz. igumbi lokuhlala, igumbi lokutyela, igumbi lokufunda kunye namagumbi okulala.
2)Khangela iindawo zokukhupha umoya apho kufuma khona ukufuma (ikhitshi kunye nezindlu zangasese) ukuze amavumba kunye nomoya ofumileyo ungatsalwa kwiindawo zokuhlala phambi kokuba kungene umoya.
3)Enye inketho kukufumana indawo zokuvula kumacala ahlukeneyo endlu kunye nendawo yokukhupha epasejini okanye indawo esembindini yendlu ukuze kuhanjiswe umoya opholileyo, oshushu kumjikelezo wendlu (umz. amagumbi okuhlala kunye namagumbi okulala) kunye iqukuqela ukuya kwindawo yokukhupha ephakathi.
4) Fumana indawo yangaphakathi kunye neendawo zokukhupha umoya umgama ohlukeneyo ngaphakathi kwamagumbi ukwandisa umoya omtsha, oshushu ojikelezayo kwisithuba.
5) Khangela unikezelo lomoya wangaphandle kunye neendawo zokukhupha umoya eziphumayo kude ngokwaneleyo ukuze uqinisekise ukuba umoya wokuphuma awutsalwanga kumoya omtsha. Ukuba kunokwenzeka, zibeke kumacala ahlukeneyo endlu.
Isondlo
Inkqubo kufuneka ibonelelwe qho ngonyaka. Ukongeza, umninimzi kufuneka enze iimfuno zokugcinwa rhoqo ezichazwe ngumenzi, ezinokubandakanya:
1) ukubuyisela izihlungi zomoya 6 okanye 12 ngenyanga
2) ukucoca iihood ngaphandle kunye nezikrini, ngokuqhelekileyo i-12 ngenyanga
3) ukucoca iyunithi yokutshintsha ubushushu nokuba yi-12 okanye i-24 ngenyanga
4) ukucoca i-condensate drain kunye neepani zokususa isikhunta, ibhaktheriya kunye nefungi 12 ngenyanga.
