Development of Decision Method for Evaluating the Applicability for Heat Recovery System in Super-Large Complex Buildings
Abstract
Currently, the numbers of super-large complex buildings, which have not only rooms requiring heating but also rooms requiring a cooling load, have increased. Therefore, the applicability of a Balanced Heat Recovery concept (ASHRAE, 2008) in which the system works year-round to recover of all the internal heat before adding external heat, is increasing. By utilizing this type of system, it is possible to maintain a set temperature by supplying small amount of energy into the system. In earlier research, Choi (1995) and Choi et al. (2008) performed similar study for resident buildings and demonstrated the importance of renewable the internal heat energy, and Chen et al. (2011) demonstrated that the heat exchange network synthesis, which is applied in industrial field commonly, can be applied for large public buildings.
