Abstract
An experimental and numerical study done to design and analysis ice storage in air conditioning system on building with three types of cooling load. The design system was active to produced thermal comfort to the building. The non-operating hours of the building was defining and used to collect ice on the out surface of pipes in the ice storage system. To predict the radius of the formatted ice an enthalpy method used with B.F.C. system used and the results compared with the experimental results from measuring the radius of the ice formatted in a rig build and run with the same boundary conditions. The theoretical results shown good coincident and the small deviation in the magnitude and not the distribution of the results is because we canceled the convection effect. In the operating hours of the building many types of pipes arrangement was examined (parallel and staggered), and many ratios of ( ) L S and ( ) T S in the ice storage. The study shows that the staggered arrangement is better for the three types of cooling load and always gives smaller volume of ice storage. In addition, the study shows that any increase in ( ) L S and ( ) T S cause increasing in the volume of ice storage. In addition, the study shows that the type of cooling load has great effect on the volume of ice storage
