NUMERICAL STUDY OF PERSONALIZED VENTILATION APPLICATION IN TOLLWAY CHARGING STATION
Split air conditioning system is commonly utilized in tollway charging station for dealing with thermal load. Outdoor air, without conditioning, is introduced passively through small opening window, which is utilized for charging tools. Because of its highly polluted ambient environment, many kinds of contaminants are introduced simultaneously. In order to improve air quality in breathing zone for the staff in an energy efficient way, personalized air is conditioned and distributed separately. Air conditioning and filtration equipments are installed above the roof of the station. Extended air duct is utilized to distribte personalized air. AIRPAK, commerical software of Computational fluid dynamics (CFD) is utilized to simulate flow fluid, age of air and predicted mean vote (PMV). Corresponding boundary conditions are measured in one tollway charging station of Hebei Province. Location of personalized ventilation air terminal devices (PV ATDs) and personalized air flow rate are utilized as variable parameters. According to the simulation results, personalized air flow rate above 54 m3/h can restrain outdoor air invasion effectively so as to diluting indoor contaminants.
