Numerical and experimental modeling of indoor air quality inside a conditioned space with mechanical ventilation and DX-Air conditioner

الملخص EN

Elevated CO2rates in a building affect the health of the occupant.

This paper deals with an experimental and numerical analysis conducted in a full-scale test room located in the Department of Mechanical Engineering at the University of Technology.

The experiments and CFD were conducted for analyzing ventilation performance.

It is a study on the effect of the discharge airflow rate of the ceiling type air-conditioner on ventilation performance in the lecture room with the mixing ventilation.

Most obtainedfindings show that database and questionnaires analyzed prefer heights between 0.2 m to 1.2 m in the middle of an occupied zone and breathing zone height of between 0.75 m to 1.8 given in the literature surveyed.

It is noticed the mismatch of internal conditions with thermal comfort, and indoor air quality recommended by [ASHRAE Standard 62, ANSI / ASHRAE Standard 55-2010].

CFD simulations have been carried to provide insightson the indoor air quality and comfort conditions throughout the classroom.

Particle concentrations, thermal conditions, and modified ventilation system solutions are a full-scale test room located in the Department of Mechanical Engineering at the University of Technology.
