Mugihe cyubushyuhe, Heat Recov Recovery ventlators (HRV) na Energy Recovery Ventilators (ERV) bikurura umwuka mwiza uturutse hanze.Uyu mwuka ukwirakwizwa murugo hamwe na sisitemu yo kwiyegurira-imiyoboro cyangwa binyuze muri sisitemu yo gushyushya ikirere.Muri icyo gihe, imyanda iherereye mu cyumba gitanga ubushuhe n’ibyuka bihumanya (urugero, igikoni, ubwiherero, ibyumba byo kumeseramo) binaniza umwuka ungana, umwuka wuzuye hanze.Rimwe na rimwe, umwuka ukururwa biturutse ku mwuka ugaruka wa sisitemu yo gushyushya / guhumeka.
Mugihe imyuka ibiri yo mu kirere inyura hagati yikintu, umwuka mwiza uhindurwamo ubushyuhe bwakuwe mu mwuka mwinshi.ERV nayo ihererekanya ubuhehere mwuka mwiza niba uyu mwuka wumye kuruta umwuka wuzuye, bizamura ihumure mumazu yumye cyane.
iyo icyuma gikonjesha gifunguye mu cyi, ingufu zumuyaga ukonje zisohoka mucyumba zikoreshwa mbere yo gukonjesha umwuka ushyushye hanze hanyuma zoherezwa mucyumba, kandi igihombo cyo gukonjesha mu nzu kigenda kigabanuka.
iyo gushyushya ubukonje bifunguye mu gihe cy'itumba, ingufu z'umwuka ushyushye ziva mucyumba zikoreshwa mbere yo kohereza umwuka ukonje mbere yo kohereza mucyumba, ubushyuhe bwo mu nzu buragabanuka.
Mugihe cyo gukonja, revers ibaho.Umwuka mwiza wo hanze ukonjeshwa numwuka uhumeka.Niba umwuka usohoka wumye kuruta umwuka mwiza, ERV yohereza ubushuhe mwuka usohoka.Iyi nzira igabanya ubushuhe kuri sisitemu yo guhumeka, ubundi bikavamo gukomeza kwinjiza umwuka wizuba murugo.
