Design Optimization of Passively Cooled Room

Journal of Energy Engineering, 1992
We consider this paper an actual design implementation of a passively cooled room, employing the night‐cooling roof‐pond method. The main intended application in our case is of cool storage of agricultural products in the region of Northern Thailand. As there have been no roof‐pond systems specifically designed for the storage of agricultural products ...
