지역냉방 용량 증설시 아이스슬러리 시스템의 적용가능성

Applicability of an ice slurry system to the enhancement of the district cooling capacity is studied. The chilled water transporting systems ( ①3 ℃/13 ℃ , ②1 ℃ /13.5 ℃ :Ice bone type=> Ice slurry system), and the district ice slurry transporting system ③ are analyzed in the view of the economic evaluation. The payback periods for the each system are as follows, ①3 ℃/13 ℃=>10.5 year, ②1 ℃/13.5 ℃ ( Ice bone type is replaced by the ice slurry system ) =>10.3 year, ③direct ice slurry transporting system=> 9.7 year. With the same transportation pipe for the chilled water transportation system (①3 ℃/13 ℃), the heat exchanging for the condition ( 1 ℃/13.5 ℃ ) is performed by the extra ice slurry system investment, the capacity is enhanced as much as 25 %, and the payback period for the extra facility is 3.9 years.
