E-50 Task/Ambient Conditioning Systems with Isothermal and Non-Isothermal Air Flow : Part 1 Environmental Investigation of Isothermal and Non-Isothermal Task Conditioning Systems

Abstract

Performances of the task/ambient conditioning systems, 3DU^+, PEM, and TU, were investigated in an environmental chamber in Kanto-Gakuin University, Yokohama. 3DU^+ and PEM could diffuse non-isothermal air as task conditioning systems. TU was installed beneath a desk to diffuse isothermal air to occupant bodies. By ventilation performance measurements, differences between ambient and task area were not obvious under task/ambient-conditioned conditions. By detail air velocity measurements, it was found that there were points where air velocities were more than 0.15 m/s.
