1. 21. Ventilation systems in Low Energy Houses: augmentation of mixing in a small-scale water model by generating resonance

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Borja Chocarro de Erauso; [2022]
   Keywords : Stratification; buoyancy frequency; resonance; mixing; passive house; water model;

   Abstract : Some passive houses are provided a warm supply flow inlet coming from a mechanical ventilation system, creating issues of shortcut ventilation as a result of an originated density layer stratification, since the supplied warm air is confined to the ceiling level. In this way, there exist several complaints of thermal discomfort and poor indoor environmental quality in passive houses. READ MORE
