  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

  3. 22. Investigation into Urea Deposit Risk by varying parameters in the control system related to urea evaporation

    University essay from KTH/Kemiteknik

    Author : Anna Sandström; [2022]
    Keywords : Urea Deposits; Urea Decomposition; Selective Catalytic Reduction; Urea Dosing; Ureautfällning; Ureanedbrytning; Selektiv katalytisk reduktion; Ureadosering;

    Abstract : I och med nuvarande och kommande lagkrav för utsläpp från tunga lastbilar finns en efterfrågan på utvecklade strategier för utsläppsminskning. För att kontrollera utsläppen av kväveoxider (NOx) används katalytisk omvandling med AdBlue (vätskeblandning av urea och vatten). READ MORE

  4. 23. Development of heat recovery solution for heavy duty truck cabs to improve energy efficiency.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Exekiel Aurelio; Rahul Acharya Rathnakar; [2022]
    Keywords : air-to-air heat recovery; air-to-liquid heat recovery; integrated thermal management system; heat wheel; heat pump; battery electric vehicle; battery electric trucks; energy savings.; luft-till-luft värmeåtervinning; luft-till-vätska värmeåtervinning; integrerat värmehanteringssystem; värmehjul; värmepump; batterielektriskt fordon; batterielektriska lastbilar; energibesparingar.;

    Abstract : The recent climate actions to reduce greenhouse gas (GHG) emissions have set the stage for decarbonizing the transportation sector through electrification, which has led to a surge in the deployment of battery electric vehicles (BEV). Trucks are no exception, which has led automakers to shift their focus toward producing Battery Electric Trucks (BET). READ MORE

  5. 24. Optimizing Energy System in a Supermarket : A case study analysis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Filip Josefsson; [2022]
    Keywords : R744; heat recovery; refrigeration system; supermarket; optimization; water-cooled condenser gas cooler; R744; värmeåtervinning; kylsystem; livsmedelsbutik; optimering; vattenkyld kondensor gaskylare;

    Abstract : With more restrictions regarding the use of refrigerants with high GWP-values, refrigeration systems that uses R744 (Carbon dioxide) as a refrigerant increases. Supermarkets are energy intense facilities where the refrigeration system utilize a significant part of the total utilized energy. READ MORE

  6. 25. Parametric study on hybrid rocket propulsion system performance measured by the system specific impulse

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Adam Bussmann; [2022]
    Keywords : Hybrid; Hybrid propulsion; Hybrid propulsion system; System specific impulse;

    Abstract : Hybrid rocket motors have become of great international interest during the last couple of years. A hybrid rocket motor is propelled by the use of a solid fuel and a liquid oxidizer. The fundamental principle of the hybrid propelled system is that the liquid oxidizer is injected into a combustion chamber to enable the combustion of the solid fuel. READ MORE
