| Abstract |
The purpose of this study is to find out how a thermal environment for the military barracks can be improvedfrom an inequality of a room temperature and discomfort of the residents with the existing radiator heating. The thermalcomfort 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 floorheating. The results are as follows: The existing heating that three radiators are installed along the external wall ismore comfortable than the radiator repositioning that one radiator is moved to the internal wall. The latter shows lowtemperature due to the inadequate management of infiltration load. But both of radiator heating is not more comfortablethan a radiant floor heating for the military barracks. A radiant floor heating can maintain the comfortable conditionowing to a relatively high temperature and uniform room temperature distribution. But, it needs to design a properperimeter zone to prevent a discomfort of the residents adjacent to the external wall due to cold draft. On the basisof this study, it is suggested that the radiant floor heating system should be adopted for the thermal comfort for themilitary barracks. |
