The impinging jet ventilation system (hereinafter referred to as IJV) has been proposed as a new air conditioning ventilation system. Properties of indoor environment with this system using impinging jet are complicated. The present paper reports fundamental properties of indoor air with distributed interior heat generation load assuming an office. The experiment was conducted in the climate chamber of which floor area was 27.0 m2, and basic properties of temperature and CO2 distributions were investigated.

A turbulent jet is the most important flow element in mechanical ventilation. Mixing ventilation is based on the properties of turbulent jets. By entrainment into the jet the ambient air is set into motion. For a jet supplied within a room the enclosure may affect the jet in several ways, through:
Ventilation strategies play an important role of enhancing thermal comfort, Indoor Air Quality (IAQ) andenergy conservation in any conditioned space. Introduced in late 90s, Impinging Jet Ventilation (IJV) isthe system that can utilize stratification, while supplying with high velocity. With this characteristic andthe simplicity of its terminal configuration, IJV has an advantage over well-known DisplacementVentilation (DV) system. In this study, IJV system was investigated for establishing the protocol used inComputational Fluid Dynamics (CFD) simulation.
Introduced in late 90’s, Impinging Jet Ventilation (IJV) is the system that can utilize stratification, while supplying with medium to high velocity. This characteristic makes IJV easy to be controlled and operated, while room Indoor Air Quality (IAQ) can
