123  Structural compatibility: Paraffin-based modules can be integrated into existing wooden, plastic, or metal frames without corrosion risk [4]. Despite its relatively high melting point, paraffin T3 is a promising material for thermal regulation in agricultural structures. With proper system design—including placement, form, and heating method—it can effectively utilize latent heat to reduce energy costs. Global studies confirm that PCM systems can raise nighttime greenhouse temperatures by several degrees, supporting sustainable agriculture with simple and effective passive technologies [4, 5]. CONCLUSIONS Paraffin T3 is a cost-effective and chemically stable phase change material (PCM) suitable for passive thermal energy storage in agricultural buildings. Its high latent heat capacity enables the reduction of daily temperature fluctuations, improving energy efficiency and microclimate stability in greenhouses and livestock facilities. However, due to its relatively high melting point (~50–55 °C), external heating sources such as solar collectors may be required for effective charging. Despite low thermal conductivity, proper design—using enhanced surface area or additives—can significantly improve performance. Overall, paraffin T3 offers a practical and sustainable solution for agricultural thermal regulation, with further research needed on hybrid PCM systems and integration with renewable energy.
