Abstract
The purpose of this study is to analyze the effect of cooling by the water atomization in the Shinkansen train base. The temperature of the train base which vehicle is cleaned and is inspected exceeds 40℃ in summer. We established the water atomization in a part of the Shinkansen train base and experimented that changing the quantity of water to grasp the characteristic of the system. The temperature descent by latent heat of water mist was 5℃〜6℃ in favorable term.
