Personal Ventilation: from research to practical use

This paper describes an ongoing demonstration project on the use of personalized ventilationin practice. Several designs of air supply devices for PV were developed, tested and optimisedbased on the efficiency of clean air supply to occupants breathing zone, control functionality,aesthetic, etc. Pilot installation of the PV system in a number of offices was used to gather better experience on the interaction between occupants and the PV system. The second stage of the project includes installation of the system and its performance in an office building.Computer based questionnaire survey on occupants comfort and performance as well as measurement of the indoor environment in the offices will be performed before and after installation of the PV system. Surveys will be performed during the following winter and summer seasons. It is expected that the obtained results will provide knowledge important for future application of PV in practice.
