Abstract
An experimental study and a theoretical study have been conducted to evaluate the performance for a closed latent heat energy storage system using energy and exergy analyses. The energy storage tank is neither fully mixed nor fully stratified. It may be considered as semistratified. Experiments were performed on sunny winter days in 1996. In this study a complete storing cycle and charging and discharging periods are considered. Energy and exergy efficiencies, total energy and exergy variations, and mean energy and exergy efficiencies are also calculated by using experimental data.

Bibliographical note
Funding Information:The use of phase change materials (PCMs) for therm al energy storage in solar he ating systems has received considerable attention. The motivation for using phase change energy storage (PCES) materials is the reduction in storage volume that can be achieve d compared to sensible heat storage systems. Abhat (1983) reviewed low-temperature PCMs in the temperature range 0] 1208 C and investigated their melting and freezing behavior. The most studied PCMs include Received 14 September 1998, accepted 14 December 1998. This study was supported by the Karadeniz Te chnical University Rese arch Fund.
