Axial fan ventilation system has been investigated in an automative parts factory, during summer. 54 axial were installed on ceiling. For the estimation of the improvement of working environment of the automotive parts manufacturing factory with the axial fan, the distribution of air velocity and temperature are investigated by experimental method. Besides, the surface temperature of the ceiling and windows is measured by thermal camera to investigate the thermal stratification.

For that study, four ventilation strategies have been evaluated in a typical bedroom in a residential building in Singapore : night-time ventilation only, daytime ventilation only, full day ventilation and no ventilation. The impacts of facade on indoor thermal environment have been analyzed too. The results are presented.

This paper demonstrates the potential of using CFD for modelling buoyancy-driven displacement ventilation in complex building structures and also the accuracy that can be expected from that use.

This paper presents a numerical method to predict the actual cooling load provided by the underfloor air distribution system (UFAD), therefore the energy consumption can be achieved.

A good performance of air diffuser is essential for an efficient ventilation and thermal comfort. Because of the Coanda effect and the influence of buoyancy, conventional diffusers cannot introduce effectively the warm air into the occupied zone in winter. So, thermodynamic diffusers have been designed to solve that problem. Both experimental and numerical models have been built, and their performances have been compared with the conventional ones.

That study aims at improving thermal comfort in the carriage of a new developed high-speed train. To figure out the air distribution pattern a CFD method is used and a prototype experiment validates the method.

The authors have tested a combined system of chilled ceiling, displacement ventilation and dessicant dehumidification. Each part is analyzed with its advantages and shortcomings. It appears that the combination of the three parts are consistent on cooling source demand and complementary on indoor comfort.
Their conclusion is that a better Comfort, IAQ and energy saving can be achieved with the association of the three technologies.

In this paper, a theoretical analysis is performed to analyze the effective air exchange rate by fluctuating flow for natural ventilation. A simple model is proposed for the analysis.

A numerical simulation and experimental measures were made on a prototype specially built for that study of a new system of air distribution inside an hospital railway coach.For the air injection into the carriage, high-induction terminal, in particular micro-jets terminal has been employed. Simulations are in adequacy with values obtained with the experimental measures on the prototype.

For that study, a mathematical analysis is applied graphically and quantitatively to investigate the multiple steady state behavior of combined buoyancy and wind driven natural ventilation system.The necessary conditions for that multiple steady states to exist are investigated along with the impact of initial conditions on the final state of the system.
