Design and experimental evaluation of phase change material based cooling ceiling system

This article deals with the possibility of using PCMs in cooling ceiling systems to reduce significantly air temperature fluctuations and energy demands for cooling. The PCM-based ceiling’s technical design was performed, a prototype realized this research. experimental verification proposed system performed determine actual parameters different operational modes their comparison same without PCM. transient simulations TRNSYS simulation software were also carried out validated experiments. Based on findings, complex application under specific climatic conditions Czechia. work contains comprehensive approach from design, through experiments partial simulations, based an economic evaluation. results show ability solution peaks by up 3.2 °C, while savings can be 27%, depending change rate. These help feasibility systems.
