That study whose aim was to determine mixing coefficients for a two-zone model of displacement ventilation was carried out in 43m2 model room equipped with various heat sources to create realistic convection air flows. The results and conclusions of modeling are presented.

An experimental study was carried out to characterize the hybrid ventilation system in residential apartment in the Porto aera. The results of the field experiments in the summer are presented .

A variety of typical air flow related problems in apartments such as air guiding, contaminant removal, draught problems are presented in this paper along with suggestions to solve those problems. CFD appears a valuable tool to obtain those solutions. Examples are given.

For that study, evaluation has been made by the authors on energy saving effect when total heat exchanger is adopted for detached houses in warm area. Their conclusion is that positive use of cross-ventilation during mid-term and during nighttime in summer season is effective for the reduction of energy consumption

That paper reports field measurement results in kitchens and washrooms in a high-rise residential building. The tracer gas method was applied to understand the removal rate of contaminant. The results lead to a re-consideration of the sizing of exhaust fans.

That study demonstrates the efficiency of longitudinal spiral recuperators, their resistance to outdropping moisture from air-cooled stream. With that type of recuperator, the effect of frosting practically does not occur. The author asserts that a ventilation system with spiral recuperators refunds the capital expenditure within one or two years.

In this paper , a correlation of three parameters (temperature, relative humidity and velocity) in a single index is proposed. That index is called the preservation index in so far as it is a measure of the inside air conditions ability for the maintenance of the required level of preservation for archaeologial artifacts.

A series of experiments were conducted in a thermal chamber room served by displacement ventilation system to investigate the effect of external heat radiation on the vertical temperature profile. The vertical temperature gradient appears clearly dependent on the type of window covers and the specific heat load.

This aim of that study is to evaluate the right time to ventilate and the effectiveness of ventilation for bake-out. A field study has been conducted in residential housing units under different ventilation and heating conditions in order to compare the ventilation strategies for bake-out . Based on the test results, it appears that ventilation during bake-out reduces indoor concentrations of pollutants.

A new mode of ventilation , the intelligent stratum ventilation, where the outlets are located at the side walls at the breathing zone level, is presented in that paper. A CFD study is undertaken and a practical example illustrates this new concept.The results are promising.
