ERV / HRV Chigadzirwa Sarudzo Yekutungamira
1. Sarudza mhando dzekuisa dzakakodzera zvichienderana nechimiro chekuvaka;
2. Sarudza kufefetera kwemhepo kunodiwa maererano nekushandiswa, ukuru uye nhamba yevanhu;
3. Sarudza izvo zvakatemwa uye huwandu hunoenderana neyakatemerwa mhepo nyowani.
Kuyerera kwemhepo kunodiwa muzvivakwa zvekugara

Muenzaniso
Nzvimbo yekamuri yekombiyuta i60 sq. metres (S=60), kureba kwemambure mamita matatu (H=3), uye mune vanhu gumi (N=10) mairi.
Kana ikaverengerwa maererano ne “Personal fresh air consumption”, wofunga kuti: Q=70, mhedzisiro yacho Q1 =N*Q=10*70=700(m³/h)
Kana ikaverengerwa maererano ne “Mhepo inoshanduka paawa”, uye fungidzira kuti: P = 5, mhedzisiro ndeye Q2 =P*S*H=5*60*3=900(m³)
Sezvo Q2> Q1 , Q2 iri nani pakusarudza chikwata.
Nezve indasitiri yakasarudzika senge zvipatara (kuvhiya uye akakosha makamuri ekuyamwisa), marabhu, maworkshops, mafambiro emhepo anodiwa anofanirwa kutariswa zvinoenderana nemirairo ine chekuita.
