  1. 1. 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

    Abstract : To meet the aims of the Paris climate agreement, it is necessary to reduce energy use in buildings. Efficient HVAC systems are a critical part in achieving a low delivered energy use. READ MORE

  4. 3. Comparison of a hybrid ventilation system and a mechanical ventilation system with heat recovery through life cycle assessment : A case study of a modern Danish office building

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Josefine Nilsson Willkomm; [2020]
    Keywords : life cycle assessment; ventilation system; environmental impact; hybrid ventilation system; mechanical ventilation system with heat recovery; livscykelanalys; ventilationssystem; miljöpåverkan; ventilation; hybrid ventilationssystem; mekaniskt ventilationssystem med värmeåtervinning;

    Abstract : The building sector is responsible for 36% of the energy usage and 39 % of all CO2- emissions in European union (EU). Therefore, it is of great interest to investigate how the building sector can become more energy efficient and lower the environmental impact. READ MORE

  5. 4. Evaluation of decentralized ventilation system with heat recovery

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Sunkavalli Kowshik Chowdary; [2020]
    Keywords : Decentralized ventilation; airflow; air draught; heat exchangers; tracer gas; Technology and Engineering;

    Abstract : Humans spend 90% of their times indoors, and maintaining a pleasant indoor environment is essential. Factors like human behaviour, combustion sources, cleaning supplies, affect the indoor environment, which could potentially affect the human health.the most common answer to controlling the indoor environment is a good HVAC system.

  6. 5. Evaluation of an Energy System for multi-family houses with Combination of Exhaust Air Heat Pump and PV : Case Study: Demonstration Building of The EU Energy Matching Project, Sweden-Ludvika

    University essay from Högskolan Dalarna/Energiteknik

    Author : Mohammad Azad; [2018]
    Keywords : EnergyMathcing project; Energy system; Novel heating technologies; On-site Renewable Energy; Low temperature heating system; combined solar technologies and heat pump; photovoltaic and exhaust air heat pump; nearly zero energy buildings; simulation of building and energy system;

    Abstract : This thesis investigated application of the heat recovery ventilation using an exhaust air heat pump and a roof top photovoltaic (PV) system for a group of three multi-family houses located in Ludvika, Sunnansjö. The buildings in the existing condition have mechanical ventilation and a centralized heating system consists of a pellet boiler as the main source and an oil boiler as back up. READ MORE
