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
