Summary

A lower type free-access floor system with less sense of confinement has been attracting attention. An analytical model is proposed for predicting the non-uniformity of supplied air velocity. It was found that the limit of the height at which a uniform supplied air velocity is obtained was 50 millimeters. Moreover, a relation was found whereby the inverse of coefficient of resistance at a diffuser up to a value of 1 is proportional to the maximum non-uniformity.
