This paper presents the simulation of a solar-powered absorption air condit
ioning system with the absorption pair of lithium bromide and water. An att
empt is made to increase the COP of the system by partitioning a single sto
rage tank into two parts. In the morning when sunshine is low, the upper pa
rt is activated, and in the afternoon, the whole (upper and lower) tank is
connected to the collector. The analysis indicates that it is preferable to
utilize a partitioned water tank rather than the normal stratified water t
ank because the cooling effect can be realized much earlier compared to the
normal stratified water storage tank. Also, the overall cooling efficiency
(cooling load to total solar energy ratio) was found to be higher for the
partitioned storage air conditioning system. (C) 2000 Elsevier Science Ltd.
