A new district cooling system using ice slurry for the uncertain cooling load of the future is presented. The chilled water produced by the absorption chillers is used for the base cooling load. The temperature of the chilled water is reduced by mixing of ice slurry depending on increasing of the cooling load. Finally, IPF of the ice slurry is increased up to 10% at the peak load. The transporting mass flow rate is decreased down to 44.7%, and the diameter of the main pipe is decreased down to 66.7%, but the diameter of the branched pipe is designed as the same size of the chilled water.

최근 겨울철과 여름철에 다양한 냉난방기기의 보급이 급증하여 최대전력에 대한 기온의 영향이 상당히 커지고 있다. 이에 따라 기온의 영향으로 인한 계절성이 급등하여 전력수요 예측결과의 불확실성을 증폭시키고 있다. 그러나 아직까지는 이러한 냉방 및 난방부하의 급증에 따른 계절성 변화에 대한 체계적인 분석 방법이 정형화되어 있지 못하다. 따라서 본 연구에서는 누적기온반응함수, 기온분포함수, 공적분 및 오차수정모형 등을 바탕으로 엄격한 통계적 검증을 거쳐 냉난방부하 추정 방법을 연구하였고, 아울러 관련 결과를 제시함으로써 향후의 전력수급에 안정적 기반을 제공코자 한다.
