Thesis supervisor: László Czétány
Location of studies (in Hungarian): Department of Building Services and Process Engineering Abbreviation of location of studies: ÉPGET
Description of the research topic:
a.) Background: The ongoing epidemic highlighted the importance of air distribution in preventing airborne infections. Many studies in the past have focused on the topic, for instance, for aeroplane boards or hospital interiors. Nowadays, as a result of globalisation, infections rapidly reach everyday scenes of life, like department stores, shopping malls or office buildings, so this problem is no longer limited to particular environments.
b.) Aim of research: The main goal of the research is to develop a novel air distribution method, which helps prevent the spread of airborne infections according to energy efficiency and reasonable investment costs. There is possibly more than one viable solution, so the different methods should also be compared to each other based on the criteria mentioned above.
c.) Tasks, main items, necessary time:
Literature review and revealing the possible research gaps. (1 semester)
Initial design of the possible system constructions in accordance with the available equipment at the laboratories of the Department. (1 semester)
Preparation for the performing measurements, initial laboratory measurements. (2 semesters)
Numerical simulation and parameter analysis. (1 semester)
Measurements and validation of the numerical data. (1 semester)
d.) Required equipment: personal computer, software licenses, laboratory, measuring equipment.
e.) Expected scientific results: Inclusion of new air distribution method among the ones currently used in Hungary and worldwide. More insight in the effectiveness of the different ventilation methods in partial load operating conditions.
