Performance analysis of a dual-stack Air-PCM heat exchanger with novel air flow configuration for cooling applications in buildings

The use of phase change materials for buildings cooling is among the most investigated techniques to improve their energy efficiency. This paper presents experimental investigations of a dual-stack latent thermal energy storage system for cooling applications in buildings. The latent energy storage consists of two PCM stacks placed in parallel. Two main design configurations of the storage are investigated based on the use of flow straightening components installed before the PCM stacks.
