Development of a Personal Air Purifier for Schoolchildren's Chair : (Part 1) Analysis of Fresh Air Contribution Ratio at Breathing Zone by using Armrest Outlet

Abstract

There are many schoolchildren who have a minor chemical sensitivity and cannot go to school just because of the activities take place such as arts & craft or just opening the text book. The solution for those children to go school is to protect them from those chemicals. In this paper will propose a personal air purifier would be effective for the children who have minor chemical sensitivity so that they could go to school and study with their schoolmates. The personal air purifier is able to attach and detach easily to a schoolchildren's chair, which is regularly used in schools. In addition, the air stream from the outlet of the personal air purifier to the breathing zone of the sitting child will be determined.
