본 연구는 대한민국의 17개 지역의 냉난방 설계를 위한 외기조건에 대한 2014년부터 2023년까지 10년간 기후변화의 영향을 분석하였다. 환기(외기)부하의 변화 추세를 분석하여 설비용량에 대한 세부적인 영향을 밝혀냈다. 해당분석은 약 3백만 개의 막대한 양의 기상청 공공 데이터를 통계화 하였다. 본 논문의 결과는 기후변화에 의해 온도가 지속적으로 상승하고 있으며 건축물 냉?난방 시스템의 설계용 외기조건의 변화와 외기부하에 미치는 영향도를 정량적으로 확인한 것이며, 향후 기준 변경에 대한 근거자료로 큰 의미가 있을 수 있다. |

This study analyzed the impact of climate change over the 10-year period from 2014 to 2023 on outdoor air conditions for cooling and
heating design in 17 regions of Korea. It examined the trends in ventilation (outside air) load to assess its impact on system capacity. The
dry bulb temperature for cooling design increased in most regions, with 15 regions experiencing an increase at the temperature distribution
with the 1.0% risk rate over the entire period. During the cooling period, at the temperature distribution with the 2.5% risk rate, temperatures
rose by up to 1.7°C in 16 regions. The wet bulb temperature decreased in three cities, leading to a slight reduction in enthalpy. For heating
design, the dry bulb temperature increased in all regions at the 1.0% risk rate for the entire period, and by up to 3.4°C at the 2.5% risk
rate during the heating period. During cooling, ventilation load increased by an average of 19.3% in most regions, but decreased by an
average of 4.1% in three cities and remained unchanged in two cities. For heating, ventilation load decreased in all regions, with an average
of 4.7%. This study quantitatively confirms that temperatures are continuously rising due to climate change. The impact of changes in
outdoor air conditions and ventilation loads on the design of building cooling and heating systems is significant and provides a basis for
future adjustments to codes or standards. |
