D-3 Semi-Personal Air-conditioning System for Sickroom by Displacement Ventilation with Radiant Panel : (Part 11) Validation of Prediction Models of Temperature and Contaminant Concentration Profile

Abstract

This paper shows the theoretical predictions of the vertical distribution of contaminant concentration and based on the calculation of previous study. It is called "developed interface layer model". This model is based on contaminant balance by convection and diffusion. In this model, "interface layer" including the contaminant interface is assumed. There is diffusive transfer of the contaminant across the interface. At the upper edge and lower edge of the interface, the diffusion is not considered and convective flow transfer the contaminant. The stagnation of contaminated air is considered in this model.
