Abstract
Using personalized ventilation systems in office buildings, important energy saving might be obtained, which may improve the indoor air quality and thermal comfort sensation of occupants at the same time. In this paper, the operation testing results of an advanced personalized ventilation system are presented. Eleven different air terminal devices were analyzed. Based on the obtained air velocities and turbulence intensities, one was chosen to perform thermal comfort experiments with subjects. It was shown that, in the case of elevated indoor temperatures, the thermal comfort sensation can be improved considerably. A series of measurements were carried out in order to determine the background noise level and the noise generated by the personalized ventilation system. It was shown that further developments of the air distribution system are needed.

The slight air blown on the chest and headdraught of the occupant besides indoor should airflow distributions obtained for different air terminal devices with low turbulence intensities, it was airflow distributions different air terminal devices with low turbulence intensities, it provide slight coolingobtained sensationfor without draught perception
After analyzing the air velocities and stated that four might be used for the ALTAIR PV system: SAR circular perforated ATD, KV 100, was stated that four might be used for the airflow distributions obtained for different air terminal devices with low turbulence intensities, it
Summary
In European countries, buildings account for 40% of the total energy consumption [1]. Levesque et al demonstrated that, without new climate policies and drastic changes in the energy use, the global final energy need of buildings could increase from 116 EJ/yr in 2010 to anywhere from 120 to 378 EJ/yr in 2100 [7] According to their results, buildings’ energy demand will be dominated by the energy use of appliances, lighting, and space cooling, while the share of heating and cooking decrease. Santamouris analyzed the energy use of buildings assuming three different scenarios: based on low, average, and high future development [8] He predicted a range of the expected cooling energy demand in 2050 assuming various boundary conditions. In the case of properly insulated buildings, even small heat loads may lead to high indoor air temperatures and the cooling energy need increases while the heating energy demand decreases.
