Emzamweni wezindlu ezonga ugesi, umbuzo wokuthi ingabe izakhiwo ezintsha zidinga Ukungenisa umoya ngeMechanical Ventilation with Heat Recovery (MVHR) izinhlelo ziya ngokuya zidingeka. I-MVHR, eyaziwa nangokuthi i-ventilation yokuvuselela ukushisa, ivele njengetshe legumbi lokwakhiwa okusimeme, ehlinzeka ngesisombululo esihlakaniphile sokulinganisa izinga lomoya wasendlini kanye nokongiwa kwamandla. Kodwa kungani lobu buchwepheshe bubaluleke kangaka ezindlini zanamuhla?
Okokuqala, ake siqonde ukuthi i-MVHR ihlanganisani. Emgogodleni wayo, amasistimu e-MVHR asebenzisa idivayisi ebizwa ngokuthi i-recuperator ukuze adlulise ukushisa kusuka emoyeni ophuma kudala kuye emoyeni omusha ongenayo. Le recuperator iqinisekisa ukuthi kufika ku-95% wokushisa kugcinwa, kunciphisa kakhulu isidingo sokushisisa okwengeziwe. Ekwakhiweni okusha, lapho amazinga okufakwa kwe-insulation ephakeme futhi kungangeni moya kuqala, i-MVHR iba yinto ebaluleke kakhulu. Ngaphandle kwawo, ukunqwabelana komswakama, ukuminyana, kanye nezinga lomoya eliphansi kungalimaza kokubili ukwakheka nempilo yabahlezi kuwo.
Umuntu angase azibuze ukuthi ukungena komoya okungokwemvelo kunganele yini. Kodwa-ke, ezakhiweni ezintsha ezivalwe ngokuqinile, ukuthembela kuphela ekuvuleni amafasitela kungasebenzi, ikakhulukazi ezindaweni ezibandayo. I-MVHR inikeza umoya ohlanzekile ongaguquguquki ngenkathi igcina ukufudumala, okwenza kube isidingo sonyaka wonke. I-recuperator ngaphakathi kweyunithi ye-MVHR isebenza ngokungakhathali, ngisho noma amafasitela ehlala evaliwe, iqinisekisa ukuthi amandla awachithwa.
Ngaphezu kwalokho, izinzuzo zidlulela ngalé kokonga amandla. Izinhlelo ze-MVHR zifaka isandla endaweni ephilayo enempilo ngokuhlunga izinto ezingcolisayo, izinto ezingezwani nazo, kanye nephunga. Emindenini, lokhu kusho izinkinga ezimbalwa zokuphefumula nokunethezeka okukhulu. Indima ye-recuperator kule nqubo ayikwazi ukugcizelelwa—inhliziyo yesistimu, evumela umoya wokubuyisa ukushisa ukuthi usebenze ngaphandle komthungo.
Abagxeki bangase baphikise ngokuthi izindleko zokuqala zokufaka i-MVHR ziyenqatshelwe. Kodwa-ke, uma kubhekwa njengotshalomali lwesikhathi eside, ukonga ezikweletini zokushisisa kanye nokugwema okungaba khona ukulungiswa kwesakhiwo okumba eqolo ngenxa yomswakama kuqeda ngokushesha izindleko zangaphambili. Ukwengeza, njengoba imithetho yokwakha iphokophela ekuhlosweni kwe-net-zero carbon, i-MVHR ayisakhetheki kodwa iyisidingo sokulandelwa kwemithetho ezifundeni eziningi.
Sengiphetha, izakhiwo ezintsha ngokungangabazeki ziyazuza ezinhlelweni ze-MVHR. Ikhono le-recuperator lokubuyisela ukushisa, kuhlanganiswe nendima yesistimu ekuqinisekiseni izinga eliphezulu lomoya, kuyenza ibe yingxenye ebalulekile yokwakhiwa kwesimanje. Njengoba silwela ukwakha amakhaya alungele imvelo futhi akwazi ukuhlala kuwo, umoya wokubuyisa ukushisa ugqama njengesici okungaxoxiswana ngaso. Kubakhi nabanikazi bezindlu ngokufanayo, ukwamukela i-MVHR kuyisinyathelo esiya ekusaseni elisimeme, elinethezekile.
