79 stone. Furthermore, the mass of paraffin required was 23.6 times lower than that of the crushed stone, highlighting the superior energy density of latent heat storage systems. Analysis of the experimental temperature curves revealed that the temperature variation of water and crushed stone can be satisfactorily approximated by a GaussAmp-type function, whereas the temperature evolution of greenhouse air and paraffin is better described by a cubic function. The agreement between the mathematical model and experimental data for greenhouse air temperature reached 98.8%, indicating high model accuracy and reliability. Thus, the latent heat storage system based on modified paraffin T3 demonstrates significantly higher efficiency in terms of specific heat storage capacity. However, the sensible heat storage system using a vertical packed bed of crushed stone offers advantages in terms of structural simplicity, lower cost, and ease of integration into existing greenhouse infrastructures without substantial reconstruction. Therefore, the final selection of a thermal energy storage system should be based on a comprehensive assessment of energy efficiency, material costs, system complexity, and integration feasibility within a given greenhouse application.
