  1. 11. 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

  5. 14. The Energy Savings Potential of a Heat Recovery Unit and Demand Controlled Ventilation in an Office Building

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Martin Fagernäs; [2021]
    Keywords : Demand Controlled Ventilation; DCV; Heat Recovery Unit;

    Abstract : The building sector is responsible for approximately 40 % of the total energy usage in Sweden. In office buildings the heating, ventilation and air conditioning system can account for up to 55 % of the energy usage. In order to reduce the energy usage of the heating, ventilation and air conditioning system different control methods are often used. READ MORE

  6. 15. Numerical Investigation of the Near FieldZone Flow Behavior of Isothermal CornerImpinging Jet Ventilation Using CFD

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Too-chukwu C. Ogbuagu; [2021]
    Keywords : Ventilation; Computational fluid dynamics;

    Abstract : Abstract The impinging jet ventilation's importance in providing better air distribution and energy-efficient operation, as well as both its heating and cooling flexibility potential cannot be overemphasized. This is because acceptable indoor air quality and its environmental conditions are essential to occupant’s wellbeing, comfort, productivity, and improved cognitive function. READ MORE
