Chilled beam system has been suggested as an alternative for the conventional air conditioning system. And it is being used in high-performance buildings in Europe and North America. Recently, chilled beam systems have been introduced to several buildings in Korea as well. It is, therefore, necessary to review their energy performance and indoor thermal comfort in correlations with Korean weather. This study used basic VAV(Variable Air Volume) as the HVAC system. The study carried out simulations using EnergyPlus v8.4 to evaluate the changes in energy performance and indoor thermal comfort when using active chilled beam system. The results of the simulation show approximately 22% reduction in annual energy consumption when active chilled beam system was used to replace the VAV system. Also, the evaluation of comfort time ratio, a ratio of the time in which the thermal comfort range was satisfied during the entire air-conditioning time of cooling season, revealed that the thermal comfort time ratio of VAV system was 46%, while that of active chilled beam system was 73%. In conclusion, utilizing active chilled beam system in office buildings helps more energy conservation and provides comfortable indoor thermal environment with less air flow supply. |
