내무생활관의 난방시 쾌적성 향상 방안

The purpose of this study is to find out how a thermal environment for the military barracks can be improved from an inequality of a room temperature and discomfort of the residents with the existing radiator heating. The thermal comfort of a radiator heating and a radiant floor heating are compared and analyzed by means of CFD simulation (Airpak 2.1). The simulations for two cases are conducted : radiator repositioning and the application of a radiant floor heating. The results are as follows: The existing heating that three radiators are installed along the external wall is more comfortable than the radiator repositioning that one radiator is moved to the internal wall. The latter shows low temperature due to the inadequate management of infiltration load. But both of radiator heating is not more comfortable than a radiant floor heating for the military barracks. A radiant floor heating can maintain the comfortable condition owing to a relatively high temperature and uniform room temperature distribution. But, it needs to design a proper perimeter zone to prevent a discomfort of the residents adjacent to the external wall due to cold draft. On the basis of this study, it is suggested that the radiant floor heating system should be adopted for the thermal comfort for the military barracks.
