Thermal Energy Storage in Greenhouses: A Brief Critical Review

Abstract This paper examines modern approaches to the design and modeling of thermal energy storage (TES) systems for solar greenhouses. It is shown that integrating TES with solar collectors helps stabilize the indoor microclimate and reduce fossil fuel consumption. Particular attention is given to the application of phase change materials (PCMs), which offer high energy storage density and the ability to maintain a nearly constant temperature during phase transition. Key factors affecting TES performance are analyzed, including thermal stratification, PCM selection, tank geometry, and heat transfer enhancement techniques (fins, metal foams, nanoparticles). Durability issues are also discussed, such as PCM degradation resistance, sealing, and corrosion resistance of containers. Special emphasis is placed on the use of numerical methods such as the finite difference method, computational fluid dynamics (CFD), and TRNSYS for analyzing transient charging and discharging processes. It is shown that integrated dynamic models enable consideration of interactions among all system components and allow real-time optimization of control strategies.
