1. 26. Modelling, Simulation and control of a Shortest Path Enthalpy Change Air Handling Unit with Liquid Desiccant

   Master-uppsats,

   Författare :Marcus Wilkens; [2021]
   Nyckelord :modelin; simulation; control; dehumidification; temperature control; sorption; desiccant; CVP; SPEC;

   Sammanfattning : In an abundance of industries, production lines and facilities, a correct indoor climate is an integral part to ensure the quality of the products and also very important for its occupants. To ensure a high quality air climate it is not enough to control the air temperature, air humidity is of at least equal importance. LÄS MER

3. 27. En kvantitativ utvärdering av ett lågenergihus i subarktiskt klimat : – gällande energianvändning, inomhusklimat och fuktvandring

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Författare :Jonathan Gustavsson; [2020]
   Nyckelord :Lågenergihus; subarktiskt klimat; fuktvandring; energianvändning; inomhusmiljö;

   Sammanfattning : Low-energy houses are a good concept for reducing energy use during the building's use. Especially when studies have shown economic profitability in buildings that meet the requirements for the definition of low-energy houses - that the energy performance is at least 25% better than the building standard from the Swedish National Board of Housing, Building and Planning.

   Sammanfattning : Increasing CO₂ emission is considered as the main reason for global warming in the world. One of the reasons for producing CO₂ is using of fossil-based materials in the construction projects. LÄS MER

5. 29. Neural Network Based Model Predictive Control of Turbulent Gas-Solid Corner Flow

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Signaler och system

   Författare :Simon Wredh; [2020]
   Nyckelord :computational fluid dynamics; machine learning; system identification; control theory; multi-phase flow; gas-solid flow; rans; lagrangian particle tracking; neural network; model predictive control; bio-aerosol;

   Sammanfattning : Over the past decades, attention has been brought to the importance of indoor air quality and the serious threat of bio-aerosol contamination towards human health. A novel idea to transport hazardous particles away from sensitive areas is to automatically control bio-aerosol concentrations, by utilising airflows from ventilation systems. LÄS MER
