| Abstract |
Heat acquirement caused by envelope system and load caused by infiltration of vestibule are large part of total cooling load in refrigerated warehouse. Especially, the vestibule of refrigerated warehouse is a place where infiltration most happens than anywhere else because of different temperature between indoor and outdoor space. Therefore, the load of refrigerated warehouse may sharply decrease when the load of vestibule decreases.
In this paper, we defined the types of vestibule through investigating actual conditions about refrigerated warehouse that operates now. And then, based on this investigation results, we measured change of temperature and figured out thermal characteristics of the type of vestibule by using down-scale model. After that, we found the amount of air change rate in order to estimate the load of air change easily in facility plan. |
