초록

본 연구의 목적은 열환경 제어 시 동적 착의량의 적용 필요성을 확인하는 것이다. 이를 위해 주거용 건물의 실내 열 쾌적성에 대한 비교 분석을 세 가지 제어 방법으로 수행했다: 1) 건구온도(DBT), 2) 고정 착의량 기반 PMV, 3) 동적 착의량 기반 PMV. DesignBuilder를 통해 주거 환경 모델링 및 각 제어 시뮬레이션을 수행하였고 PMV 및 PPD 지표를 통해 열 쾌적성을 분석하였다. 그 결과, DBT 제어 및 고정 착의량 기반 PMV 제어와 달리 동적 착의량을 적용한 PMV 제어는 계절에 상관없이 모든 시간대에서 PMV, PPD의 쾌적 범위를 만족하였다. 이를 토대로 동적 착의량을 반영한 PMV 제어가 기존 다른 제어 방법보다 실제 재실자에게 쾌적한 열환경을 제공할 수 있음을 확인하였다.

The purpose of this study is to confirm the necessity and significance of applying a dynamic clothing insulation for controlling the thermalenvironment. For this purpose, the comparative analysis of indoor thermal comfort in the residential building was conducted with threedifferent control methods: 1) DBT (dry-bulb temperature)-based control, 2) PMV (predicted mean vote)-based controls reflecting the fixedclothing insulation, 3) PMV-based control reflecting the dynamic clothing insulation. DesignBuilder was employed for a residential buildingmodeling and the thermal comfort analysis which was accessed with PMV and PPD (predicted percentage dissatisfied) indicators. As a result,the PMV-based control applying the dynamic clothing insulation satisfied the comfort ranges of the PMV and PPD at all times regardless ofthe season. On the other hand, in the case of the DBT-based control, the average PMV value was out of the comfort range in both seasons,and the PPD value was more than twice that of the PMV-based control reflecting the dynamic clothing insulation. In addition, PMV-basedcontrol reflecting fixed clothing insulation resulted in a slightly cold condition in the morning and at night in both seasons as presentingPMV values below –0.5 and PPD values over 10%. In conclusion, from this study, the possibility was confirmed that the PMV-based controlreflecting dynamic clothing insulation can provide a comfortable thermal environment for the occupants. Therefore, it is necessary to applythe accurate value of the clothing insulation in order to comfortably control the thermal environment, and a follow-up research should beconducted to develop a prediction model of the real-time clothing insulation.
