REALIZATION OF HIGH IPF ICE SLURRY FOR DISTRICT COOLING
이윤표,SANG HOON LEE,유호선 대한설비공학회 2010 International Journal Of Air-Conditioning and Refr Vol.18 No.3
The Production of high IPF (ice packing factor) ice slurry was realized. The ice slurry maker which can efficiently produce ice slurry under ice particles in-flowing condition was revised. We removed the stagnant region at the top of the ice slurry maker, thereby high IPF ice slurry was realized. The IPF controller with 6 mm diameter holes could not control IPF in a pipe. This is because ice particles in ice slurry flow exist homogeneously not only at the upper part but also at the bottom part. We changed the hole size at the surface of the IPF controller by means of fine meshes, which, then, increased the IPF in the pipe by 70% when the mesh size was 80 μm or less.
지역냉방용 아이스슬러리 수송시스템의 배관방식에 따른 특성
이윤표,정재동,윤석만 대한설비공학회 2006 설비공학 논문집 Vol.18 No.7
The characteristics of ice packing factor(IPF) at the ice slurry system using one line type are compared with the system using two lines type. The installation space for one transporting line is saved at the one line system. For the one line type, the ice packing factor is reduced along the downstream, but for the two lines type, the ice packing factor is fixed. For the one line system, mass flow rate in the main line is fixed along the downstream, but for two lines system, the mass flow rate in the main line is reduced along the downstream. For one line system, along the down stream after IPF=0, the temperature at the main steam is increased, and the extracted mass flow is increased.The initial IPF, at which the IPF is not arrived at zero upto the final node, is proposed for the B area.
