Thermo-Aeraulic Simulation of Mono Façade Natural Ventilation

Abstract:

Natural ventilation is an energy efficient alternative for reducing the energy use in buildings, achieving thermal comfort and maintaining a healthy indoor environment. Differences in wind pressure along the façade and differences between indoor and outdoor temperatures create a natural air exchange between indoor and outdoor air. These physical processes are complex, and predicting ventilation rates is difficult. This paper presents a method for determining natural ventilation air flow in single-façade thermo-air system by simulating the room using the program TRNSYS 16. Theoretical checking of the airflow obtained by simulation was performed by comparing the thermal response in the room following the simulation, with interior temperatures measured during the experiment.
