Research Abstract

The aim of this study is to develop a wind hole type cooling system for agricultural facility using slopes in mid-mauntinas regions. We buried a pipe in upper slope of the agricultural vinyl house to cool the facility using air density diference. Yield of tomato of the cooled house is biger than that of uncooled one.
