Abstract
This study is an analysis of equivalent temperature in its role as an evaluation index used when measuring thermal comfort inside cars. In this report, a new equivalent temperature was deduced by considering the actual heat movement from the body to the environment. This equivalent temperature reflects the convection heat transmission rate, the radiation heat transmission rate, and the kinds of clothing surrounding the human body. The study also clarifies an internal structure of the coefficient that hangs in the constant value and 3 treated paragraphs in equivalent temperatures as outlined by Madsen. After analyzing a range of applications for this equivalent temperature and its effectiveness it is possible to confirm that there is no great difference from other equivalent temperatures as long as it is used within certain environmental parameters.
