1. 1. Ventilation for reduced indoor spread of Covid 19 and similar diseases : A literature review focusing on hospital environments

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Cyrus Ourak Pour; [2023]
   Keywords : COVID-19; SARS-CoV-2; Ventilation system; Mixing ventilation MV ; Displacement ventilation DV ; Under floor air distribution UFAD ; Ultraviolet light UV ; HEPA filter; COVID-19; SARS-CoV-2; Ventilationssystem; Blandningsventilation; Deplacementventilation; Luftfördelning under golv; Ultraviolett ljus; HEPA-filter;

   Abstract : Today, a significant portion of individuals’ time is spent indoors, estimated at approximately 90% of their total time. This raises concerns about the transmission of Coronavirus Disease 2019 (COVID-19) instigating Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) and similar viruses and highlights the critical role of ventilation systems in indoor environments, which this study aims to investigate.

3. 2. CFD study of the different inlet configurations and airflows in a room with IJV

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Christos Stiapis; [2022]
   Keywords : Ventilation; CFD; Impinging Jet Ventilation;

   Abstract : A method of providing ventilation using impinging jets (IJV) utilizes stratification while delivering air at a high velocity. As a result of this attribute and the simplicity of its terminal construction, IJV offers an advantage over the well-known Displacement Ventilation (DV) system. READ MORE

4. 3. Ventilation efficiency measurements - a comparison between three supply air methods

   University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Max Henriksson; Henrik Nilsson; [2016]
   Keywords : Ventilation efficiency; air exchange efficiency; local ventilation index; mean age of air; comparison; mixed ventilation; displacement ventilation; Technology and Engineering;

   Abstract : This study compares the two traditional ventilation methods ; mixed ventilation and displacement ventilation, with a new type of dif fuser which attempts to solve the problem with blockage of the diffuser for the displacement ventilation. This new diffuser called Airshower is a product developed by Airson engineering AB whom is also the company where all simulations and tests for this study were performed in a built office space.

5. 4. Analysis of three ventilation systems in an office: Mixing, displacement and confluent jet ventilation system. : Analysis of temperature gradient, tracer gas and thermal comfort.

   University essay from Avdelningen för bygg- energi- och miljöteknik

   Author : Julio J. Peña Malo; Igor Panjkov Zafra-Polo; [2013]
   Keywords : Ventilation systems; mixing; displacement; confluent; confluent jet; thermal comfort; temperature gradient; tracer gas;

   Abstract : Scandinavian countries have always been the first in investigation and development of new ventilation systems. In the last years, engineers from Finland and Sweden are studying a new ventilation system known “Confluent jet ventilation system” which is trying to improve displacement and mixing results.

6. 5. Design of a ventilation system for carbon dioxide reduction in two gym rooms

   University essay from Avdelningen för bygg- energi- och miljöteknik

   Author : Ander Barroeta; [2013]
   Keywords : Ventilation system; Displacement ventilation system; Carbon dioxide;

   Abstract : This project is mainly focused on the improving and design of the ventilation system of two rooms at different levels of a gym (Friskis and Svettis in Gävle, Sweden) to reduce the  concentration to never be higher than 1000 ppm. For this purpose, several field measurements were performed in different locations and situations. READ MORE
